Safety Precautions
The machine is only intended for water-wash use.
Do not allow minors to use the machine.
Do not hose down the machine with water.
The machine's door lock must under no circumstances be bypassed.
If the machine develops a fault, this must be reported to the person in charge as soon
as possible. This is important both for your safety and that of others.
The machine is not intended to be used by people (including minors) with reduced
physical or mental capacity or lack of experience and knowledge. Such people must
be instructed in the use of the machine by a person who has responsibility for their
safety. Minors must be supervised to ensure that they do not play with the machine.
All external equipment which is connected to the machine must be CE/EMC-approved
and connected using an approved shielded cable.
Warnings
The service manual contains the following warnings concerning serious personal injury.
Next to each warning is a reference to the page and section where the warning text is located
in the manual.
DANGER
Take care when measuring the motor control system since all components have a
potential difference of approximately 300V in relation to protective earth and neutral.
The components will contain dangerous voltages when the green LED on the motor
control board is on.
The motor control system will remain live for 10-30 seconds after cutting the power to
the machine and the motor has stopped running.

The machines feature an electronic programme
unit with fixed washing programmes that may be
changed using optional accessories. The programme unit also has an in-built self-diagnosis
programme, which increases the possibilities for
quick troubleshooting.
The motor is frequency-controlled and is controlled by an advanced motor control. This allows
precise and flexible control of the motor rpm for
any application.
The machines are supplied to customer specifications with e.g. electric or steam heating or no
heating, and may be connected to various combinations of cold, warm and hard water.

Function
General
2
This section presents a general overview of the functions of the machine.
Most functions are then presented in detailed in separate chapters later on
in this service manual.
The machine is freely suspended, which means the outer drum and motor
are mounted on a supporting ”cradle” that rests on four shock absorbers
for dampening the imbalance in the machine.
The washer drum (inner drum) is belt driven by a motor. This motor is located at the bottom of the machine and is mounted on the cradle with a belt
tensioner. The inner drum is mounted to the outer drum at the rear plate
with two bearings sealed against leakage with sealing rings.
The drain valve is a water-controlled diaphragm valve alternatively, an
electrical drain valve or drain pump.
The door is of sturdy type that is interlocked with a lock module when in
operation.
The control panel contains a program knob for selecting the fixed wash
programs and a display.
The program unit is mounted inside the control panel. Contactor, water
valves, etc., are located at the back of the machine.

The control panel contains a program knob and
a display. The panel can also be equipped with
two preset buttons.
Program unit
The control panel and display are used by:
• the user to select the machine’s fixed wash
programs, to select up to two options for
each wash program and for information on
the wash process and any fault indicators.
• service personnel for navigation and control
of the program unit’s service program.
• programming personnel for setting and program adjustment in the program unit’s software.
4
If present, the preset buttons are used for direct
start of two preset wash programs.
6211
Using information on torque values from the
motor, the weight of each wash is measured
before each wash program in order to adapt the
amount of water used for washing.
4
The program unit controls the water valves, drain
valve and heating via an I/O board in the rear
electrical module. Control signals to external
units, such as detergent pumps or external water
valves can also be engaged here.

The washer drum (inner drum) is belt driven by a
frequency controlled motor. The motor is located
on a motor shelf under the outer drum and has
been arranged with a belt tensioner.
Motor control is microprocessor controlled and
can control the acceleration of the drum, its rpm
and its retardation very precisely.
Motor control communicates with the program
unit through a serial interface.
The machine’s motor and motor control are described in more detail in the section Motor.

The door lock is electromechanical with twin safety breakers. The lock is bi-stable, i.e. the lock
must be given an active signal from the program
unit to lock as well as unlock the door.
7
1
A separate circuit integrated in the program unit
checks and controls the locking and unlocking
of the door through a lock module. The circuit
has separate controls that the drum is empty
and that it is stationary. Through sensors in the
lock module, the circuit checks the door’s closed and locked position. Together with other
controls the program unit conducts, this will
guarantee the door cannot be opened by mistake.
The machine’s door and door lock are described in more detail in the section Door and door
lock.

Description of fault codes and causes
Fault code 01, NO WATER
This fault code is generated by the programming CPU card.
When filling with water, the level specified by the wash program must be
attained within a certain time. This time is normally set to 10 minutes but
can vary depending on the type of machine and the software. If the filling
time eceeds the maximum allowed filling time, fault code 01 will be displayed.
Long filling times can be caused by a blocked filler valve, defective filler
valve, a break in the cable between the filler valve control board, defective
valve control board, leaking level system, etc.
Fault code 02, DOOR OPEN
This fault code is generated by the programming CPU card. The fault code
can only arise during an on-going wash program.
This fault code will be displayed if the input for closed door signals that the
door has been opened during an on-going wash program.
This can be caused by a bad or defective door lock, loose cable to door
lock, problem with door lock edge connection.
Fault code 03, DOOR LOCK FAIL
This fault code is generated by the programming CPU card. The fault code
can arise at program start. If the door lock doesn't lock within a certain
time after program start, this fault code will be shown.
This fault code will also be displayed if the door lock for closed door signals that the door has been unlocked during an on-going wash program.
This can be caused by a bad or defective door lock, loose cable to door
lock, problem with door lock edge connection.
25
Troubleshooting
26
Fault code 04, NTC LOW TEMP
This fault code is generated by the programming CPU card. This fault code
is displayed if the temperature around the NTC sensor is below approx. -9
degrees C.
A low temperature means the resistance in the sensor is too high, above
approx. 23.7 kohm. This can be because the machine has been standing
outdoors, an open circuit in the sensor, a break in the cable to the sensor,
etc.
The resistance should be as shown in the table below:

Fault code 05, NTC HIGH TEMP
This fault code is generated by the programming CPU card. This fault code
is displayed if the temperature around the NTC sensor exceeds +98 degrees C.
A high temperature means the resistance in the sensor is too low, lower
than approx. 350 ohm. This can be caused by a short circuit in the sensor,
break in the cable to the sensor, etc.
Fault code 06, WATER IN MACHINE
This fault code is generated by the programming CPU board. This fault
code may appear only in the case of rapid advance to the end of the
program. The fault code will appear if the level system has not indicated
“empty drum” within a certain time (approx. 3 min). This time may vary
depending on the size of the machine.
Action:
• Check drain for dirt.
• Blow through the level hose and check that it is not blocked and does
not contain any water.
• Check in the service program that the level control is working correctly.
• Adding too much detergent
Troubleshooting
Fault code 07, DRUM OVERFILLED
This fault code is generated by the programming CPU board. The fault
code arises if the drum has been filled with water above a predetermined
level during an on-going wash program. It can be caused by a blocked
level hose, drops of water in the level tube, defective filler valve, defective
electronic filler control, etc.
Action:
• Blow through the level hose and check that it is not blocked and does
not contain any water.
• Check in the service program that the level control is working correctly.
• Check using the service program that all the water valves are working
correctly.
Fault code 08, NO HEATING
This fault code is generated by the programming CPU board. The fault
code means that the temperature is rising too slowly when heating is
active. The limit for this fault code is normally set to a water temperature
increase of approx. 3°C per 10 minutes but can vary depending on the
type of machine and the software.
The fault code can be caused by a defective heater element, a break in the
power supply to the heater element, defective heater contactor, etc.
On machines built for washing mops, it can be caused by too low a level in
the program stage. The lowest level for a mop program in the main wash
with heating is 90 scale units.
27
Troubleshooting
28
Fault code 09, KLIXON
This fault code is generated by the programming CPU board. The fault
code means that the temperature in the motor has been so high that the
klixon breaker in the motor has been triggered. It can be caused by overloading the motor due to an overloaded drum, low rpm for long periods,
defective klixon breaker in motor, short in cable between motor and CPU
board, etc.
Fault code 09, DRUM OVERFILLED
(only in coin operated machines)
This fault code is generated by the programming CPU card. The fault code
is caused by the mechanical level control in the machine, by safety reason
a doubled level system. The fault code arises if the drum has been filled
with water above a level that normaly should have generated fault code 07.
It can be caused by a blocked level hose, drops of water in the level tube,
defective filler valve, defective electronic filler control, etc.
Action: see fault code 07.
Fault code 10, DRUM NOT DRAINED
This fault code is generated by the programming CPU card. The fault code
arises if the water in the drum is not below a predetermined level when a
drain period has been completed in the wash program. It can be caused
by a blocked drain, blocked level hose, a water drop in the level hose, defective level control, restricted drain lines to the machine, too many machines emptying simultaneously into drain pipes that are too narrow, etc.
Action:
• First check the drain installation and that the waste water can flow freely out from the machine without any restrictions.
• Check the drain valve in the machine with regard to dirt.
• Blow through the level hose and check that it is not blocked and does
not contain any water.
• Check in the service program that the level control is working correctly.
Troubleshooting
Fault code 11, UNB. ON AT PROG. START
This fault code is generated by the programming CPU board. The fault
code means that the mechanical imbalance breaker is already active when
the wash program starts. It can be caused by a defective imbalance breaker, mechanical problem making the imbalance breaker always active,
short in the edge connection or cables, etc.
Fault code 12, PROGRAM FAILURE
This fault code is generated by the programming CPU board. This fault
code means that one of the CPU board memories can be defective.
Action:
• Try reloading the software into the machine memory. If this does not
help, the CPU board will have to be replaced.
Fault code 13, NO MOTOR COMM.
This fault code is generated by the programming CPU board. The fault
code arises if the CPU board cannot communicate with motor control via
the communication cable.
Actions:
• Check that there is power reaching the motor control.
• Then check that the indicator LED on the motor control is on. The LED
can be seen by looking down by the motor control edge connections.
• Check also that the communication cable between the CPU board and
the motor control is intact and not damaged. Measure also with a reference instrument to see whether there is contact between all the leads
in the communication cable.
Fault code 14, LEVEL ADJUST
This fault code is generated by the programming CPU board. The fault
code arises if the circuit board’s internal level system has not been calibrated by the manufacturer.
29
Troubleshooting
30
Fault code 15, EMERGENCY STOP
This fault code is generated by the programming CPU board. The fault
code arises if the emergency stop switch has been activated on the machine.
The cause can be inadvertent activation of the emergency stop, defective
emergency stop switch, incorrect or shorted cable, etc.
Fault code 17, DOOR LOCK
This fault code is generated by the programming CPU card. The fault code
arises if the door lock is locked at the start of the wash program, i.e. that
the door is locked although the CPU board has not requested locking. This
fault code will be shown if one try to start a program when the DLCU has
given a fault code.
Fault code 18, START NOT ALLOWED
The machine’s program unit has been disabled by a superior monitoring
system.
Actions
• Get in touch with the supplier of the monitoring system for possible
causes of the monitoring system disabling operation of the wash machine.
Fault code 19, MASTER COMM.
Communication with superior system has been broken. The cause can be
a fault in the network connections, damaged cable, defective monitoring
system, etc.
Action:
• Firstly, contact the supplier of the monitoring system for possible causes of the monitoring system not communicating.
Troubleshooting
Fault code 20, I/O MCU INTERLOCK
This fault code is generated by the programming CPU board. The program
controller has read from the motor control or I/O board that the interlock is
not active. The reason for interlock failure can be a problem with the hatch
lock, damaged motor supply cables or the I/O board with interlock voltage
etc. The most probable fault source is the I/O board.
Fault code 21, I/O COMMUNICATION
This fault code is generated by the programming CPU board. The program unit cannot communicate any longer with one or more I/O boards
in the machine that it has communicated with before. The cause can be a
problem with the machine’s internal communication cables or that one or
more I/O boards have lost their address.
Action:
• (Requires password) Check the machine’s internal communication
cables. Readdress all the I/O boards in the system using the service
program if the cables are not at fault.
Note.
If only one I/O-card in mascine, press the service button on the I/Ocard about 10 seconds or untill the LED goes out. Now I/O.card 1 will be
addressed as No. 1.
Fault code 22, OIL
This fault code is generated by the programming CPU board. The fault
code indicates low oil level in the oil reservoir for the oil lubrication. It can
be caused by a lack of oil, defective sensor, shorted cable, etc.
Action:
• Fill with oil first. If this does not help, check sensor and cables.
31
Troubleshooting
32
Fault code 23, NO I/O ADDRESSED
The fault code means that there is no I/O board addressed in the system
at all.
Action:
• (Requires password) Readdress the existing I/O board from the service
menu.
Fault code 24, CHECKSUM FROM DLCU
This fault code is generated by the programming CPU board. The program
unit has detected a fault in the internal communication in the DLCU-processor.
Action:
• Replace the CPU board.
Fault code 27, LEVEL OFFSET
This fault code is generated by the programming CPU board. The fault
code arises if the level system indicates a level at the start of the wash
program (when the drum should be empty) that exceeds what the program
unit can compensate for automatically. This can be caused by blocked
drain, blocked level hose, a drop of water in the level hose, leaking level
system, defective level control, etc.
Action:
• Check drain for dirt.
• Blow through the level hose and check that it is not blocked and does
not contain any water.
• Check in the service program that the level control is working correctly.
Troubleshooting
Fault code 28, CPU/DLCU LOW LEVELS
The DLCU contains a mechanical level monitor which ensures that there
is no water in the machine when the lock opens. To ensure that the level
monitor functions correctly, the mechanical level monitor is compared with
a nominal value generated by the CPU, which is compared with the electronic level check.
When the water level exceeds the nominal value, a check is made to
ensure that the mechanical level monitor is switched on, and if so, a fault
code is generated.
Reason:
• The level controller can be damaged:
• Cross talk in the level controller electrical system.
• Leakage in the level controller’s air hoses.
• Incorrect nominal value, possibly caused by a fault in the electronic
level controller.
Action:
• Check the level controller function. (Switch-on level = 40 mm, switch-off
level = 15 mm Wg)
• Check the cables and their connections. The voltage across the level
controller should be 0 V when the water level is < 15 mm Wg and 5 V
when water level is > 40 mm Wg.
• Check that the level hoses are not blocked. Blow clean all the hoses in
the level system.
Fault code 31, HEAT SINK TOO HOT
This fault code is generated by the motor control. There is a temperature
sensor (NTC) mounted on the motor control cooling flange next to the power transistors in the output stage. If the temperature of the cooling flange
gets too high (> 90°C) the fault code will be set to protect the transistors.
The cause of high cooling flange temperature can be e.g. a stiff drum in
combination with intensive use and high ambient temperature. There may
also be a fault in the motor (sticking bearings or short circuit in windings,
which impairs the efficiency of the motor). There may also be a fault in the
motor control temperature measuring circuits.
Actions:
• Make sure the drum turns easily.
• Check the value on the fault code counter for fault code 31.
• Check the last 8 motor control fault codes.
• Start a 90°C normal program with load on continuous operation and
measure the temperature of the motor and motor control.
• Replace the defective part.
33
Troubleshooting
34
Fault code 32, MOTOR TOO HOT
This fault code is generated by the motor control. Each time the motor is
started from stationary, the motor control will first measure the resistance
between two phases in the motor. The motor control processor governs
the output transistors so that a determined DC current flows between two
phases in the motor winding. The actuation of the transistors is a measure
of the voltage applied to the winding and the resistance can be calculated using the current and voltage values. The resistance can then be
converted to a temperature since the winding resistance at 20°C and the
temperature coefficient are known. If the average value of the four latest
temperature readings is higher than the maximum motor temperature (e.g.
130°C), the ”Motor too hot” fault code will be activated.
The cause of high motor temperature can be a stiff drum, possibly in combination with intensive use and high ambient temperature. There may also
be a fault in the motor (sticking bearings or short circuit in windings, which
impairs the efficiency of the motor). There could also be a contact fault in
the connectors between the motor control and the motor or a fault in the
motor cable. A fault in motor control temperature measurement circuits
can also occur.
Actions:
• Make sure the drum turns easily.
• Check the value on the fault code counter for fault code 32.
• Check the last 8 motor control fault codes.
• Measure the three phases to the phase resistors on the motor control
motor connector (disconnect motor control and take the reading in the
cable connector) to make sure they are the same.
• Start a 90°C normal program with load on continuous operation and
measure the temperature of the motor and motor control.
• Replace the defective part.
Troubleshooting
Fault code 33, NO INTERLOCK
This fault code is generated by the motor control. The motor control must
be powered with 230V/50 Hz on the interlock input in order to drive the
motor. This signal is confirmation that the door is closed and locked. Motor control receives its commands to rotate the drum from the timer via a
serial communication link between the motor control and timer. Since the
timer also has access to the interlock signal, the timer must never send a
run command to the motor control if the interlock signal is missing. If this
does happen, the ”No interlock” fault code will be activated.
The cause of this fault code being activated can be e.g. a break in the
cable leading the interlock signal to the motor control. There may also be
a fault in the connector in the door lock, which connects 230V/50Hz to the
interlock signal. A fault in the interlock circuits of the motor control can
also set this fault code.
Actions:
• Use a measuring instrument to check that the interlock signal comes on
X302:1-2 when the door lock is activated. Read also bit 1 in the second
bye under ”Motor Status” in the service program (the bits are numbered
from 0 to 7 where bit 0 is on the far right). If bit 1 in the second byte is 1
then the lock is open, while a 0 indicates that the lock is closed.
• Replace the defective part when it has been located.
35
Troubleshooting
36
Fault code 35, MOTOR SHORT CIRCUIT
This fault code is generated by the motor control. The motor control reads
the power consumption of the motor continuously. If the current for some
reason gets too high (= exceeds a certain limit), the motor control will cut
the current to the motor. After the motor has stopped (= tachometer indicates stationary motor), the motor control will attempt to restart it. If the
motor control then detects high motor current again, the ”Short circuit
motor” fault code will be activated. If on restarting after a first short circuit,
the motor control rotates normally, a fault code will not be activated.
This fault code can be activated for a number of reasons:
• Short circuit in motor
• Short circuit internally in motor winding (impaired efficiency, higher current consumption)
• Short circuit in motor cables
• Short circuit in connectors
• Drops of water causing short circuits in the motor connector
• Short circuit in the motor control output transistors
• Bad contact in tacho signal
• Bad contact in interlock signal
Actions:
If the fault is a stable one, it is generally not difficult to locate the defective
unit through resistance measurement and testing with the service program.
Further information can be obtained by studying the contents of ”MCU
FAULT LOGGER”. Study the following:
• SHORT CIRCUIT 2 (specifies how many times fault code 35 has been
active)
• SHORT CIRCUIT 1 (specifies how many times the current limit has been
exceeded. The difference between short circuit 1 and short circuit 2
indicates how many times there has been a short circuit 1 that has not
been confirmed when restarting the motor).
• LAST FAULT CODE N/8 (shows the 8 latest fault codes)
• TACHO CUT-OUT LOW RPM (can give a clue in case of intermittent
faults)
• TACHO CUT-OUT HIGH RPM (can give a clue in case of intermittent
faults)
Troubleshooting
Fault code 36, INTERLOCK HARDWARE
This fault code is generated by the motor control. The motor control must
be powered with 230V/50 Hz on the interlock input in order to drive the
motor. The interlock circuits in the motor control have been split into two
channels so that a component fault in motor control cannot give a false
confirmation that the door is locked. These two channels are checked
against each other. If this check gives an incorrect result, the ”INTERLOCK
HARDWARE” fault code will be activated.
The reason for this fault code being activated can be attributed to a fault in
the interlock circuits in motor control.
Action:
• Replace motor control.
Fault code 37, LOW DC VOLTAGE
This fault code is generated by the motor control unit. The motor control
unit constantly measures the voltage over the mains input. If the voltage
is too low (= falls below a certain limit), the motor control unit will shut off
the current to the motor. Once the motor has stopped (= the tacho sensor
indicates that the motor is stationary), the motor control unit checks to see
whether the input voltage is still low. If it is, a fault code is activated: ”LOW
DC VOLTAGE”.
The reason for this fault code being activated can be low mains voltage or
that the machine’s on/off switch has been operated in an unsuitable manner. Further information can be obtained by studying the contents of ”MCU
FAULT LOGGER”:
• UNDERVOLTAGE 2 (specifies how many times fault code 37 has been
active)
• UNDERVOLTAGE 1 (specifies how many times the voltage has dropped below the limit. The difference between undervoltage 1 and undervoltage 2 indicates how many times there has been an undervoltage 1
without it being confirmed when the motor has stopped).
• LAST FAULT CODE N/8 (shows the 8 latest fault codes)
Undervoltages can be registered even during normal operation. Consequently, a small number of registrations need not mean that there is a fault
in the motor control.
Measure:
• Check that the supply voltage is stable and never drops below nominal
voltage - 10%.
• Check that the fuses and cables are not faulty.
• Check the supply voltage in the network cabling and at the motor control system in the machine.
37
Troubleshooting
38
Fault code 38, HIGH DC VOLTAGE
This fault code is generated by the motor control unit. The motor control
unit constantly measures the voltage over the mains input. If the voltage
is too high (= exceeds a certain limit), the motor control unit will shut off
the current to the motor. Once the motor has stopped (= the tacho sensor
indicates that the motor is stationary), the motor control unit checks to
see whether the input voltage is still high. If it is, a fault code is activated:
”HIGH DC VOLTAGE”.
The reason for this fault code being activated can be high mains voltage
(e.g. power surge). Further information can be obtained by studying the
contents of ”FC FAULT LOGGER”:
• OVERVOLTAGE 2 (specifies how many times fault code 38 has been
active)
• OVERVOLTAGE 1 (specifies how many times the voltage limit has been
exceeded. The difference between overvoltage 1 and overvoltage 2
gives the number of times overvoltage 1 has occurred without it being
confirmed when the motor has stopped).
• LAST FAULT CODE N/8 (shows the 8 latest fault codes)
Overvoltage registrations can also occur if there is a bad contact in the
tacho signal. Check also the following registers:
• TACHO CUT-OUT LOW RPM (number of short tacho interruptions
during wash rpm)
• TACHO CUT-OUT HIGH RPM (number of short tacho interruptions
during extraction rpm)
Action:
• Check the tacho cables if there are many registrations in the TACHO
CUT-OUT registers.
Troubleshooting
Fault code 45, MOTOR NOT FOLLOW
This fault code is generated by the motor control. The motor control must
always receive information on the rotation of the motor from the tacho
sensor in order to rotate. If the tacho sensor is not working, the motor can
rotate for max. 10 seconds during the starting process. After this period,
the ”MOTOR NOT FOLLOWING” fault code will be activated.
Reasons for this code being activated can be:
• Break in the cables between the tacho sensor and the motor control
• Break in connectors in tacho cables
• Break in one of the phases to the motor (cables or connectors). This
fault can be suspected if the motor does not rotate for 10 seconds (the
motor will not start with only two phases).
•Fault in tacho generator
•Fault in tacho circuits in the motor control
Further information can be obtained by studying the contents of ”FC
FAULT LOGGER”. Study the following:
• MOTOR NOT FOLLOWING (specifies how many times fault code 45 has
occurred)
• LAST FAULT CODE N/8 (shows the 8 latest fault codes)
• TACHO CUT-OUT LOW RPM (can give a clue in case of intermittent
faults)
• TACHO CUT-OUT HIGH RPM (can give a clue in case of intermittent
faults)
Action:
• Replace the defective part when troubleshooting is complete.
Fault code 51, CHECKSUM FROM CPU
DLCU has detected a fault in the internal communication between DLCU
and CPU. The DLCU processor will reset itself when the fault has disappeared.
CPU reads the fault message when the program starts and finishes and
generates a fault code, the fault message is ignored between these two
occasions.
Reason:
Strong interference from surrounding equipment etc. can cause fault codes.
Action:
Re-set the fault codes. If the fault codes can not be re-generated or if they
return, rectify the adjacent equipment that causes the interference. If this
does not help, try changing the CPU board, since the interference sensitivity of different CPU boards can vary to some extent.

Troubleshooting

Fault code 52, CHARGE CIRCUIT
DLCU contains an arming circuit that is charged when the door lock coil is
to be activated. For safety reasons, this arming circuit must be discharged
when the door lock coil is not to be activated.
If the arming circuit for operating the door lock is charged when it is not
supposed to be, a fault message will be sent to the CPU processor. If the
fault ceases, the message will not be sent to the CPU.
CPU reads the fault message when the program starts and finishes and
generates a fault code, the fault message is ignored between these two
occasions.
Cause:
• The error can have been caused by overloads and/or defective components in the DLCU, or caused by defective components in the CPU.
Measure:
• If the error cannot be corrected, replace the CPU unit.
Fault code 53, CPU/DLCU HIGHLEVELS
The DLCU contains a mechanical level monitor which ensures that there
is no water in the machine when the lock opens. To ensure that the level
monitor functions correctly, the mechanical level monitor is compared with
a nominal value generated by the CPU, which is compared with the electronic level check.
When a program starts or terminates, a check is made to ensure that the
mechanical level monitor is switched off, and if this is not the case, a fault
code is generated.
Reason:
• The level controller can be damaged:
• Open circuit in the cables for the level controller.
• Blocked air hoses in the level controller system.
Action:
• Check the level controller function. (Switch-on level = 40 mm, switch-off
level = 15 mm Wg)
• Check the cables and their connections. The voltage across the level
controller should be 0 V when the water level is < 15 mm Wg and 5 V
when water level is > 40 mm Wg.
• Check that the level hoses are not blocked. Blow clean all the hoses in
the level system.
Troubleshooting
Fault code 54, TACHO, NO SET SIGNAL
DLCU counts the tacho pulses from the motor in order to guarantee that
the drum is stationary when the door is opened. To ensure that the signal
from the tacho generator is working correctly, DLCU compares the tacho
signal to a default value from the CPU processor, which is due to the CPU
having activated the motor. The tacho signal should always correspond
to the default value and if the tacho signal is present without the default
value, a fault message will be generated to CPU.
The fault message is filtered in such a way that the drum must rotate and
stop twice without the ”should rotate” signal being present before a fault
message is sent to CPU.
The DLCU processor will reset itself when the fault has disappeared.
CPU reads the fault message when the program finishes and generates a
fault code, the fault message is ignored between these two occasions.
Reason:
The fault can be caused by cross talk in circuits in the CPU, or caused by
damaged components in the CPU.
Action:
If the fault returns after a reset, change the CPU.
41
Troubleshooting
42
Fault code 56, SET SPEED DOOR OPEN
DLCU counts the tacho pulses from the motor in order to guarantee that
the drum is stationary when the door is opened. To ensure that the signal
from the tacho generator is working correctly, DLCU compares the tacho
signal to a default value from the CPU processor, which is due to the CPU
having activated the motor.
If the default value is on when the door lock is unlocked, a fault message
will be sent to CPU.
The DLCU processor will reset itself when the fault has disappeared.
CPU reads the fault message when the program finishes and generates a
fault code, the fault message is ignored between these two occasions.
Reason:
The fault can be caused by cross talk in circuits in the CPU, or caused by
damaged components in the CPU.
Action:
If the fault returns after a reset, change the CPU.
Fault code 58, SET SIGNAL NO TACHO
DLCU counts the tacho pulses from the motor in order to guarantee that
the drum is stationary when the door is opened. To ensure that the signal
from the tacho generator is working correctly, DLCU compares the tacho
signal to a default value from the CPU processor, which is due to the CPU
having activated the motor. The tacho signal should always correspond
to the default value and if the tacho signal is not present when the default
value is present, a fault message will be generated to CPU.
The fault message is filtered in such a way that the default value should
have been on for 2 seconds; if this is the case, a check is made that the
pulses from the tacho sensor are present when the default value ceases.
The DLCU processor will reset itself when the fault has disappeared.
CPU reads the fault message when the program finishes and generates a
fault code, the fault message is ignored between these two occasions.
Reason:
• The fault can be caused by breaks in the circuits for the tacho sensor,
or caused by a fault in the magnet in the tacho sensor.
• Collateral damage due to a fault in the motor system.
Action:
• If there is no fault in the tacho sensor or the motor system, and the fault
returns after a reset, change the CPU.
Troubleshooting
Fault code 60, ACTUATOR CIRCUIT
The DLCU processor controls the door lock actuator coil. The DLCU processor checks continuously that the coil is engaged. DLCU can detect a
break in the circuit (>50 kohm) (DLCU cannot detect a short in the circuit).
If there is a break in the actuator circuit, CPU will be notified; the fault
message will disappear if the fault ceases.
CPU reads the fault message when the program starts and finishes and
generates a fault code, the fault message is ignored between these two
occasions.
Reason:
•The fault can be caused by a break in the cables between the hatch lock
and the CPU, or caused by a fault in the hatch lock solenoid.
•Fault or break in the CPU circuits.
Action:
•If the fault returns after a reset, and is not caused by a fault in the hatch
lock or the cables for the hatch lock, change the CPU.

Unbalance detection
When the drum in a drain sequence starts its acceleration from wash
rpm to distribution rpm, the extreme unbalance measurement will start
once about 90% of the distribution rpm has been attained. Subsequently,
during the entire remaining super unbalance measurement, the distribution
time and during the entire subsequent extraction time, the program unit
will detect whether there is any extreme unbalance.
In case of extreme unbalance that can arise if e.g. a spring strut is defective or when washing in sacks, the acceleration will be stopped to wait for
the drum to stop. If extreme unbalance arises during:
a. distribution or during super unbalance measurement, the drain sequence will restart from the beginning. The number of restart attempts can
be changed in the system data but is usually set to 5. The value can
also be changed via configuration 2.
b. extraction, the program will stop and move to the wash sequence after
extraction.

I/O modules
General
Washing machines may be equipped with either one or two I/O modules:
• I/O module 1 controls internal machine functions and is always installed in the machine prior to delivery. It controls outputs to water valves,
waste discharge and heating.
• I/O module 2 is installed as an optional extra, controlling the external
functions of the machine, i.e. inputs from payment and booking systems and outputs to detergent pumps.
The functionality of I/O module inputs and outputs is dependant on the
parameter software downloaded to the machine’s program device. The
function options for the I/O modules are indicated by a letter in the program designation for each module and, together with the article number
of the parameter software, shown in the ARTICLE NUMBER menu of the
service program as per the following example:
Program designation
3A02 CH EL/DS 465H EF
Function options I/O module 1
(internal functions)
Article number shown in the
service program
Function options I/O module 2
(external functions)
432662204 A E
If the second letter (I/O module 2) appears in lower case, it means that the
machine is not fitted with I/O module 2 but the downloaded parameter
software is I/O module 2 enabled.
Program designation
3L02 LG1 CH EL/DS 465H Ae
I/O module 2 is enabled for the
specified function option
Article number shown in the
service program
432662204 A e
If the machine subsequently fitted with I/O module 2, the module will acquire the function option as specified by the second letter once the new
I/O module has been addressed.

The door locks consists of the following:
• Door lock, which contains
- An actuator that locks the door lock and
also has two built-in micro switches, S4a
and S4b. The actuator is bi-stable, i.e., it
has two stable positions: locked door and
unlocked door. The actuator must receive
a pulse to lock and unlock the door lock.
S4a and S4b are both closed when the
door is locked.
- A micro switch S3 that is closed when the
door is closed.
- An emergency opening button that can
be used to open the door lock in an emergency.

Function
The door lock locks the door
When the door is closed (closed door lock switch S3), the programme unit
may request door locking by applying a voltage of 200-240 V on the door
lock controller A31 input X92.
2
The following check is made by the A31 card prior to locking of the door:
• No water in drum - input "level" from level guard B2 is closed = 0 V
• Drum not turning - pulse frequency on input "Tacho" from rotation
sensor B3 less than 0.4 Hz.
When the above conditions are met, the card A1 outputs a closing pulse
on output D0 to the door lock actuator/coil, which then locks the door. The
micro switches S4a and S4b in the actuator/door lock are closed when the
door is locked. These micro switches feed voltage to:
• The output relays on the programme unit card. The relays control the
machine’s drain and water valves as well as heater switch-on.
• Interlock signal for motor control (input X302) that releases the motor
start prevention state.
Programme operation is now possible.

The programme unit requests door unlocking by applying 0 V on input X92
of the door lock controller.

The following check is made prior to unlocking of the door:
• No water in drum - input "Level" from level guard B2 is closed = 0 V
• Drum not turning - pulse frequency on input "Tacho" from rotation
sensor B3 is less than 0.4 Hz.
When the above conditions are met, the door lock controller outputs an
opening pulse on output D0 to the door lock actuator/coil, which then
unlocks the door. Micro switches S4a and S4b now interrupt the actuator/
door lock and the I/O card 1 relays lose all voltage to prevent the motor
from starting (interlock signal on motor controller input X302). The drain
and water valves of the machine are now disabled and the heater and motor cannot be switched on.

Motor
1
The motor is fitted in a bridge carrier under the
outer drum. It drives the washing drum using a
drive belt.
The motor is frequency-regulated and is controlled by a microcomputer control. The various speeds for normal operation, distribution
speeds and extraction as well as acceleration/
retardation can be controlled with a high degree of precision.
The motor winding is protected against overload due to the fact that the motor control unit
monitors the winding resistance of the motor.
The motor is connected directly to the motor
controller via a cable with quick connectors.

The motor control unit is microcomputer controlled and is situated under the top cover of the
machine, right above the outer drum.
Motor control U1
The unit consists of a PCB (mother board) fitted
on a heat sink that does double-duty as part of
the housing.
The cable harness is directly connected to
the PCB, voltage supply input and the voltage
supply to the motor using connectors; the other
cables are connected with flat connectors to the
PCB.
A detailed description of input and output cables
is presented in the section “Function”.
Depending on the machine size, this unit comes
in four different versions. The units have different
sizes in order to be able to control motors of different sizes. Larger machines also have ventilation fans, however the function and connections
are identical.

The motor control communicates with the programme unit via a serial twoway interface. With the help of the motor control, the programme unit can
control not only the instantaneous motor rpm, but also with high precision
the acceleration and retardation of the motor in order to reach the target
rpm. The motor control continuously replies with information to the programme unit PCB regarding the current operating state and sends reports
if an error occurs.

The motor control is also able to deliver the
various instantaneous and output values during
constant speed, acceleration and retardation.
These values are used to calculate the weight of
the loaded laundry and to detect any load imbalances. A separate imbalance switch can also be
connected to the motor control.
The safety system of the machine includes
double detection of the door lock. Both the
programme unit and motor control use different
switches to detect proper door locking. The motor cannot start unless both switches verify the
door is locked.

The drain valve is situated on a flange at the bottom of the outer drum and can be accessed from
the front after removing the front cover.
The drain valve consists of the following principal
parts:
• Lower part with rubber diaphragm.
• Piston and cylinder.
• Pressure plate and recoil springs.

Drain valve
106
Function
2
The drain valve uses the water pressure in the
cold-water inlet to close the valve. A feed hose
is connected between the water inlet and the
control valve.
When the control valve operates (drain valve
should be closed), the control valve opens the
water pressure onto the feed hose, which is connected to the lower part of the drain valve. When
the lower part is filled with water, the lower part
diaphragm pushes up the piston. The piston lifts
the pressure plate against the drain valve rubber
diaphragm, which in turn forms a seal against
the outer drum, effectively closing the valve.

When the drain valve should be opened, the
control valve changes position to allow the water
pressure to the lower part of the drain valve to
close, instead opening the return hose to the
drain. The pressure plate recoil springs pull the
pressure plate back, upon which the piston is
pressed back into the cylinder. The water from
the lower part is fed through the feed hose and
the control valve to the drain.

designed for use with powder and liquid detergent. The compartment is divided into four subcompartments as follows:
1
109
• Compartment 1 - For pre wash with powder
or liquid detergent.
2
• Compartment 2 - For main wash with detergent powder.
• Compartment 3 - Rinse.
• Compartment 4 - Main wash with liquid detergent or, bleaching-agent.
The connections for incoming water are situated
on the rear side of the compartment. Compartments 3 and 4 each have one connector, while
compartments 1 and 2 each have two connectors, one for cold water, the other for warm
water.

Preventive maintenance
Preventive maintenance
To maintain correct and proper functioning and to prevent interruption of
service, the following maintenance scheme should be adhered to.
The maintenance interval should be adapted to how frequently the machine is used.
Daily
• Check the door and door lock:
- Let the door remain open and try starting the machine. The machine
should not start.
- Close the door, start the machine and try opening the door. It should
not be possible to open the door until the drum has stopped turning.
- Check that the door does not leak.
- Clean the door seal, removing any detergent and fluff.
• Check that the drain valve does not leak during the wash cycle.
• Clean out any detergent remaining in the detergent compartment. Rapid
advance through a program and let the water rinse the compartment:
Every third month
May only be carried out by authorized personnel.
• Check that the door does not leak.
• Check the drain valve and remove any fluff.
• Inspect the interior of the machine (during an actual wash cycle to ensure that no leaks are noticed) by:
- Turning of the main power switch of the machine.
- Remove the top cover and the protective front and rear plates.
119
120
Preventive maintenance
- Verify that all internal hoses do not leak.
- Inspect the drive belt. Adjust the tension or replace if necessary.
- Check that water does not leak onto the floor.
- If the heating time is unusually long, check the heating elements. If
the water is very hard, check whether there are lime deposits on the
heating elements. Decalcify the elements if necessary. Adapt the
amount of deliming agent to the manufacturer’s guidelines.
- Never switch on the heating elements when there is no water in the
machine. This will cause the slow-blow fuse to trigger.
- Inspect the shock absorbers and coil springs. (Only EX- and
H-model).
