The programme unit contains a microprocessor
with a number of standard programmes for
normal wash cycles. New programmes,
specially prepared for specific applications, can
be easily programmed by the customer, either
using the control panel on the washing machine
or using a special computer application. The
programmes are then transferred to the
washing machine on memory cards.
5206
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.
The machines are designed for installation in
hotels, laundries, factories, hospitals, various
institutions, etc.

Door lock control A31
The door lock is an electro-mechanical type with
double safety switches. The lock is bi-stable, i.e.,
it needs to receive an active pulse from the
control in order to both lock and unlock the door.
A separate printed circuit board, called door lock
control, can be fitted onto the programme unit.
This board controls locking and unlocking. The
card has separate checks for empty drum and
stopped drum. Together with the checks built into
the programme unit, this guarantees that the
door cannot be opened by a mistake.
The door lock on the machine is described in
detail in section 29. Door and door lock.

The drum assembly is freely suspended by
springs and is allowed to move in relation to the
frame. This means a minimum of vibrations are
transferred to the frame, which implies simplified
installation since the machine need not be placed
on a concrete base.
The machine uses four coil springs between the
frame and drum assembly. Each spring is fitted
to one or two shock absorbers that dampen drum
movement.

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.

Manual
- Verify that all internal hoses do not leak.
- Inspect the drive belt. Adjust the tension or replace if necessary (see
section 30. Motor).
- Check that water does not leak onto the floor.
- If the heating time is unusually long, check the heating elements (see
section 40. Heating). 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.

General information about troubleshooting
The troubleshooting section is used to pinpoint a fault on the machine to a
specific defective component or unit.
If the power supply is interrupted, the programme memory will keep the
select programme in its memory for approx. 3-5 minutes.
Within this time period, the machine automatically restarts after the power
interruption.
Precautions
Only authorized personnel is allowed to troubleshoot the machine.
Prior to commencing troubleshooting, pay close attention to the precautions
in section 1.
If the power is on, be very careful when working on the the machine.
DANGER
Be very careful when measuring the motor controller since all
components have a potential difference of about 300 V compared to
Ground and Neutral.
When the green LED is lit, all components are powered with
dangerous voltage.
When the power supply to the machine is interrupted and the motor
has stopped, the motor controller will does lose power until after 1030 seconds.
Measurements
For information about measurement points, components and voltages,
please refer to the wiring diagrams for the machine.

• I/O cards A11 and A12
Most smaller machines have only one card:
A11. The I/O cards are controlled by the CPU
card via a serial interface. The I/O cards
feature outputs, which, via the communication
card in the rear control unit, control various
machine functions, such as the water valves,
heating connection and drain valve. The cards
also have inputs for emergency stop and door
lock.

The programme unit of the machine consists of
the following parts:
• CPU card A1
The CPU card uses the various control
programmes in the card programme memory
to check all the functions of the washing
machine. The standard programmes are also
stored in the programme memory
(programme numbers 991 - 999) together
with any user-specified programmes.
23

I/O card 2 A12
I/O card 1 A11
CPU card A1
The CPU card controls the display card A2
(display window, control panel and the A3
card reader), I/O cards A11 and A12 and the
motor controller U1 via the serial data
interface.
• Display card A2
The display card receives data from CPU
card A1 about which text to display in the
display window. The display card converts
this data and control the display window in
order that the correct data is shown.
Display card A2
Card reader A3
The display card also senses which keys are
pressed on the keyboard and sends the
received information to the CPU card.
• Card reader A3
Using the card reader, it is possible to copy
washing programmes from the CPU card
memory to a memory card or from memory
cards to the CPU memory.
The memory cards can then be inserted in a
card reader of another washing machine or
in a reader connected to a PC. This allows
copying of washing programmes from one
machine to another or between a PC and
washing machines. The card reader is
connected to the display card A2.

• I/O cards A11 and A12
Most smaller machines have only one card: A11. On some machines,
there is a greater need for outputs, in which case two I/O cards are
used.
The I/O cards are controlled by the CPU card via a serial interface. The
I/O cards feature outputs, which, via the communication cards in the rear
electric box, control various machine functions, such as the water
valves, heater connection and drain valve. On the input connection
blocks of the communication cards, it is possible to connect signals for
control of e.g. the detergent supply.
The cards also have inputs for emergency stop and door lock ACK.

CPU card A1
Fig.

The CPU card controls all functions of the washing machine using various
control programmes in the CPU card memory. The CPU card
communicates with the I/O card, display card and motor controller using a
serial interface.
The following functions are controlled:
• The CPU card controls the water valves, detergent supply, drain and
heating using one or two I/O cards. Depending on the number of
functions to be controlled, the number of I/O cards varies between
different machines.
• The CPU card controls the alphanumeric display window on the display
card.
• The CPU card controls the motor via a motor controller.
To obtain information about the various operations of the washing machine,
the following inputs are used:
• The CPU card has inputs for e.g., temperature sensors.
• The CPU card receives information from the I/O card inputs about door
locking state and any external switches (e.g., Start/Stop and Pause).
• The CPU card has a pressure sensor to which a hose for measuring the
water level in the drum can be connected.
• The CPU card receives information from the display card about which
buttons were pressed.
Note that the CPU card does not contain any removable memory chips. If
the CPU card needs replacement, the correct software for the machine
needs to be programmed in the new card using a laptop with special
software. See the section “Replacing the CPU card”. Personalised washing
programmes can be transferred using a Smart card.

I/O cards
Fig.
The I/O cards are controlled by the CPU card and communicate via a
serial interface. Depending on the need for inputs and outputs, one
programme unit may have one or two I/O cards.
5
All inputs and outputs are switched from the I/O card to the various
functions via the communication cards in the rear electric module.
Each I/O card is connected to a separate communication card: I/O
card A11 uses communication card A21 and I/O card A12 uses
communication card A22.
There are inputs for door lock and external switches (e.g. Start/Stop
and Pause). Signals on these inputs are passed on to the CPU card.
The outputs control water valves, detergent supply, drain and heating.
The voltage supply to the CPU and I/O cards takes place via I/O card
1 A11, which feeds voltage to both the CPU card A1 and a possible I/
O card 2 A12.
Note that if the programme unit uses two cards and one needs to be
replaced, special programming is required. It is necessary to
programme the new card with the correct I/O card number (1 or 2)
using a laptop and special software. See the section “Replacing the I/
O card”.

If you answer Yes (Y):
The machine will not wait for the water to heat,
but will begin to count down the time of on the
wash sequence immediately.
The temperature of the water will, however, still
be monitored and adjusted during filling if the
answer Yes has been inserted for the question
”TEMPERATURE CONTROL OF WATER” (see
next question).
If the answer ”Yes” is in place (Yes is the default)
for the question ”HEATING RELAY ON WHEN
NOT HEATED” (see "Settings 2") the heating
relay (if machine is equipped with one) will switch
on. This means you can heat the water while
wash action is in progress. If you do not want the
heating relay to switch on, you must insert the
answer ”No” for the question ”HEATING RELAY
ON WHEN NOT HEATED”.
If you answer No (N):
The machine will heat the water to the set
temperature before the count down of the wash
sequence begins. The temperature values will be
shown on the display (if you have ”allowed” their
display).
Temperature control of water
Here you determine whether the machine will
monitor and adjust the water temperature during

Water level for quick cool-down
Here you determine the level to which the machine
fills with cold water for quick cool-down.
When you are creating a wash program, in the
module ”COOL-DOWN” there is an option for
programming ”QUICK COOL-DOWN”.
Quick cool-down means that the machine will fill with
cold water to a higher level.
This function is used mainly for reducing the
temperature of the water before it is discharged.
For information on the levels used for the various
machines, see the manual ”Programming, PCS
Program Control Unit”.

Water level after unbalance halt
Here you determine the water level to which the
machine fills after a halt in extraction due to
unbalance.
If the machine’s unbalance-sensing equipment is
activated when extraction begins, that extraction
will halt and a new attempt will begin. If you want
the drum to be filled with water to a certain level
before the drain valve opens and the machine
makes a fresh attempt at extraction, you can set
that level here. Level 0 means that the drum will
not fill.

Middle temperature cool-down
Here you determine the middle temperature for cooldown.
When creating a new wash program you can, to
prevent creasing of the load, use the COOL-DOWN
module to achieve controlled cool-down of the water
in the drum. The cool-down sequence is divided into
two stages:
1 wash temperature to middle temperature
Throughout this stage the machine will monitor
the cool-down rate, to ensure it does not exceed
the cool-down rate set (4°C per minute when the
machine leaves the factory). If the rate set is
exceeded, no water will be added until the mean
value is acceptable again.
2 middle temperature to final temperature
The rate of cool-down is not monitored during this
stage. The valve opens and shuts as you have
programmed it to do.

Under certain circumstances during a wash
program, e.g when the machine starts up again after
a halt in extraction due to imbalance, the machine
cannot find the ”on-time” and ”off-time” values for its
motor action in the current wash program. That is
when it needs to be able to find and use the default
”on-time” and ”off-time” values stored here.

Changes in ”SETTINGS 2” must be approved
by the supplier
The variables which you can change via
”SETTINGS 2” belong to a category which, if they
are changed carelessly or incorrectly, could
jeopardise the machine’s safety system(s) or its
reliability.
For this reason SETTINGS 2 is protected by a
code/password system. Every time you access
SETTINGS 2 you have to obtain a new password
from the supplier.
The system works like this:
• When you open SETTINGS 2, you will see an
eight-digit code. This code will be different each
time you open SETTINGS 2.
• You need to tell the supplier, Sweden exactly
what this code was. Using a special computer
program, they will then ascertain the four-digit
password which unlocks this code, and give it to
you. This password will work only with the eightdigit code you have noted this time.
• Once you have entered the password, you have
access to SETTINGS 2, and can change
functions as required.

Level for over-filled drum
Here you determine the water level at which the
drum will be regarded as over-filled.
Over-filling can occur if a water valve is faulty, or if
you have over-filled the machine manually.
For information on the levels used for the various
machines, see the manual ”Programming, PCS
Program Control Unit”.
Under ”SETTINGS 2” (i.e. later in this section)
there are two functions which influence the way the
machine reacts to over-filling:
”DRAIN TIME WHEN OVERFILL”
(i.e. DRAIN TIME AFTER OVER-FILLING)
If you have the answer N (No) inserted for the
function ”ERROR OVER-FILLED” (described
below, this page), the drain valve will open and
discharge water for the time inserted as a
parameter under ””DRAIN TIME WHEN
OVERFILL”. The level will be checked after that,
and the same sequence will be repeated until
the level is back to normal.
ERROR OVER-FILLED
If you answer Y (Yes): if the drum becomes
over-filled, the machine will stop and the error
message ”MACHINE OVER-FILLED” will be
displayed.
If you answer N (No): the drain valve will open
as described above.

Temperature hysteresis
Here you determine a default value for the
machine’s temperature hysteresis.
The temperature hysteresis can be programmed
individually for each wash program. However,
under certain circumstances, e.g. when the user
has set the temperature manually, the PCU may
not be able to find the temperature hysteresis
values in the current wash program. That is when
it needs to use the default value stored here.
What is temperature hysteresis?
Once the drum has filled with water to the right
level, it is heated to the wash temperature you
have programmed. During the wash the water
will cool down somewhat.
When the water temperature has reached a
lower limit, heating restarts and the water
temperature is brought back up to the correct
level.
Temperature hysteresis is the number of
degrees between the wash temperature and the
temperature at which heating needs to restart.

Temperature step in cool-down
Here you determine the maximum reduction in
temperature per minute during the first stage of
cool-down.
How does cool-down work?
When creating a new wash program you can, to
prevent creasing of the load, use the COOLDOWN module to achieve controlled cool-down
of the water in the drum. The cool-down
sequence is divided into two stages:
1 wash temperature to middle temperature
Throughout this stage the machine will monitor
the cool-down rate, to ensure it does not exceed
the limit value you are determining here. If the
rate set is exceeded, no water will be added until
the mean value is acceptable again.
2 middle temperature to final temperature
The rate of cool-down is not monitored during
this stage. The valve opens and shuts as you
have programmed it to do.

Default values, extraction time
Here you determine how long the machine will
extract at the speeds low, medium and high. Later
in this section you will find the instructions for
programming the actual speeds to be used for low,
medium, high and ”turbo” extraction.
How an extraction sequence works:
In order to extract some of the water from the
load at lower speeds, the drum does not
accelerate to its highest speed immediately.
Instead it accelerates in several steps. This
means that the drum first accelerates to a low
speed level, remains at that for a certain time,
then accelerates to a higher level, extracts at
that speed for a certain time, and so on until it
reaches its final (maximum) extraction speed. If
you program a low extraction speed, the number
of steps at the beginning of the extraction
sequence may be reduced.

Unbalance measurement
Here you determine whether the machine will
calculate unbalance before it accelerates to
extraction speed. Drum unbalance can only be
calculated in washer extractors with suspended
drums. It uses torque data from the motor control
unit to determine whether the imbalance is too
high.
For washer extractors with suspended drums
without frequence control and which have a
separate unbalance switch, the answer to this
question should be No.
If you answer Yes (Y):
The machine will calculate unbalance before
every extraction sequence.
If you answer No (N):
The machine will not calculate unbalance.

Drain open delay
Here you determine whether you want a delay
before the drain valve opens, for example if you
want the drum to have time to gather speed first,
before the valve opens.
The drain module
may be structured according to point 1 (here)
only, according to point 2 only, or a combination
of 1 and 2, according to the way you program.
1 Drain time
The drain will be open. The motor may be at a
standstill, on gentle action or normal action.
2 Distribution time
The drain will be open. The motor runs at
distribution speed. During this time the wash
load will be distributed evenly around the walls
of the inner drum.

Start extract time (i.e. Initial extraction time)
Here you determine the length of time for initial
extraction (if used).
When you are programming the ”main data” for a
wash program you can determine whether the
program is to begin with initial extraction. Initial
extraction is used to spin the load outwards against
the drum walls, which makes it absorb water more
readily on first filling. As a result of this the machine
will not require so much extra filling (repeated
topping up) later (to maintain its required water
level).
There are two other functions affecting initial
extraction which can be programmed under

this section). This function allows you to specify a
speed which the motor must drop below before
water filling can begin.
If these functions are combined, you must ensure
that the ”rollout time” will have ended before water
filling is allowed to begin, regardless of whether the
drum speed has, prior to that, dropped below the
speed specified in ”MAX. SPEED DURING
FILLING”.

Lock test delay
Here you determine the length of time between
when the door is locked and when the check
should be made of the lock’s microswitch.
When the machine commands that the door be
locked, the door lock is activated. The lock
actuates a microswitch which signals whether or
not the door is really locked.
Note that the machine always begins its wash
sequence immediately after the door has been
locked, and that the time you program here will
not affect that. If, when this check is made, the
microswitch should signal that the door is not
locked, the machine will stop and the error
message DOOR UNLOCKED will be displayed.

Time drain to open after over-filling
Here you determine how long the drain valve
should open for if the machine has over-filled,
provided you ensure that the parameter (response)
stored for the function ERROR OVER-FILLED is N
(No) (see below). The drain valve will open for the
time programmed and the level will then be
checked. If the level is still too high, the drain valve
will open again, and so on.
Over-filling can occur if a water valve is faulty, or if
you have over-filled the machine manually.
Also under ”SETTINGS 2” there are two functions
which influence the way the machine reacts to
over-filling:
ERROR OVER-FILLED
If you answer Y (Yes): if the drum becomes
over-filled, the machine will stop and the error
message ”MACHINE OVER-FILLED” will be
displayed.
If you answer N (No): the drain valve will open
as described above.
LEVEL OVERFILL (i.e. DRUM OVER-FILLED)
Here you specify the level at which the drum is
considered to be ”over-filled”.

When a wash program has ended, the text above

If the door is not unlocked within a reasonable

Door open delay for ”motor lost”
Here you determine the length of time during which
the door will be prevented from opening if, (in
machines with frequency control) the MCU loses
control of braking at the end of extraction.
In machines with frequency-controlled motors it is
the MCU which ensures that the motor and drum
are braked smoothly after extraction speed.
If anything should go wrong at this stage so that
the MCU loses control of the braking process
(colloquially referred to as ”motor lost”) the MCU
will inform the PCU. If the program has reached the
final extraction sequence, the PCU will ensure that
the door cannot be opened until the time you
program here has elapsed.

Time delay before door opening
Here you determine the length of time during which
the door will be prevented from opening if the
machine has detected a fault-error and is displaying
an error message. This must give enough time for
the water to empty and drum speed to be reduced.
Please note that the water will not be emptied as a
result of all types of error. In the case of the HIGH
TEMPERATURE error, for example, the door will
remain locked even though the time you have
programmed has elapsed. One reason for this is to
prevent the risk of a fire if the electrical heating
equipment is still switched on and heating.

Upper and lower temperature limits for errors
Here you determine the temperature limits for the
errors HIGH TEMPERATURE and LOW
TEMPERATURE respectively.
If the HIGH TEMPERATURE error is flagged, this
usually indicates an short circuit in the sensor or
wiring. LOW TEMPERATURE usually indicates a
open circuit in sensor or wiring. That is why the
default value for the low temperature limit is -9 C. If
the sensor cools to this temperature, the resistance
from the sensor will be 0 ohms, which corresponds
to a short-circuit.

Default value, extraction time
Here you determine the various speeds (low,
medium and high) for extraction. The instructions
for determining the length of extraction times are to
be found earlier in SETTINGS 2.
How an extraction sequence works:
In order to extract some of the water from the
load at lower speeds, the drum does not
accelerate to its highest speed immediately.
Instead it accelerates in several steps. This
means that the drum first accelerates to a low
speed level, remains at that for a certain time,
then accelerates to a higher level, extracts at
that speed for a certain time, and so on until it
reaches its final (maximum) extraction speed. If
you program a low extraction speed, the number
of steps at the beginning of the extraction
sequence may be reduced.

Start extract speed (i.e. Initial extraction
speed)
Here you determine the speed of initial extraction.
When you are creating a wash program you can
determine (under ”Main data”) whether it is to
begin with initial extraction. Initial extraction is used
to spin the load outwards against the drum walls,
which makes it absorb water more readily on first
filling. As a result of this the machine will not
require so much extra filling later.

extraction which can be programmed under

MAX SPEED DURING FILLING
Max. speed during filling
Here you specify a speed which the motor must
drop below when it is being braked after extraction.
Water filling will not take place until the motor has
slowed to this speed. This function is useful for
frequency-controlled motors.
Another function, intended primarily for motors
without frequency control, is called ”ROLLOUT
TIME” (accessed via SETTINGS 2, described
earlier in this section). ROLLOUT TIME allows you
to specify a time period which must elapse before
water filling starts.
If these functions are combined, you must ensure
that the ”rollout time” will have ended before water
filling is allowed to begin, regardless of whether
the drum speed has, prior to that, dropped below
the speed specified in ”MAX. SPEED DURING
FILLING”.
Rollout time, if activated/
implemented may change the

Imbalance detection
Imbalance can be split into three different types: extreme imbalance
measurement, mechanical imbalance interruption and super imbalance
measurement.
Extreme imbalance measurement
In a drain sequence, when the drum starts its acceleration from washing
rpm to extraction rpm, the extreme imbalance measurement starts when
90% of the distribution rpm has been achieved. After this, for the
remainder of the super imbalance measurement, the distribution time and
throughout any subsequent extraction time, the programme detects
whether extreme imbalance occurs or not.
In the event of extreme imbalance, which can occur if e.g. a spring strut is
damaged or if washing is being performed in sacks, the acceleration is
interrupted and it is necessary to wait for the drum to stop. If extreme
imbalance occurs during:
a. distribution or during super imbalance measurement, the drain
sequence starts again from the beginning. The number of attempted
restarts can be set in the system data, but is usually set to 5 attempts.
This value can also be altered via configuration 2.
b. extraction, the extraction is interrupted and the programme skips to the
next washing sequence after extraction.
Mechanical imbalance interruption (detection via mechanical
imbalance switch)
The same as extreme imbalance, except that if the imbalance switch is
activated during a part of the washing programme that is run at washing
rpm, the drum stops for a few seconds and then automatically starts up
again.

Super imbalance measurement
Super imbalance measurement is the normal imbalance measurement. Its
task is to ensure that the machine is not overloaded during extraction, as
well as to ensure that the number of missed extractions is as small as
possible.
Super imbalance measurement starts a few seconds after the drum has
reached distribution rpm. The delay is there to allow the motor rpm to
Ôsettle down’ so that it is as stable as possible.
The magnitude of the imbalance is measured and compared first with a
fairly low imbalance limit value 1. If the imbalance exceeds this limit value,
the drum is slowed down to a lower rpm in order to achieve redistribution
of the clothes. It then accelerates again without stopping at the distribution
rpm again, after which a new imbalance measurement is carried out. The
number of attempts at limit value 1 may be set in the system data and can
also be altered in configuration 2. The value is normally set at 3.
If the imbalance is below the limit value, extraction starts at the extraction
speed specified in the programme after the distribution time has elapsed.
If the imbalance still does not drop below limit value 1 after three attempts,
the imbalance is instead compared with a slightly higher permitted
imbalance value, limit value 2. If the imbalance exceeds this limit value,
the drum is slowed down to a lower rpm in order to achieve redistribution
of the clothes. It then accelerates again without stopping at the distribution
rpm again, after which a new imbalance measurement is carried out. The
number of attempts at limit value 2 may be set in the system data and can
also be altered in configuration 2. The value is normally set at 2.
If the imbalance is suddenly lower than one of the two limit values, the
extraction starts with the extraction speed programmed in the programme.
The reason for the use of two limit values, both of which produce the same
extraction rpm, is that in order to look after the machine’s mechanism, it is
desirable in the first instance to extract with as low an imbalance as
possible.
In the same way as above, the imbalance is compared with a further two
limit values, limit value 3 and limit value 4. However, each of these gives a
reduced extraction rpm if the imbalance is below the limit value. The
number of attempts at limit values 3 and 4 may be set in the system data
and can also be altered in configuration 2. The value for each is normally
set at 2.

Manual
23. Programme unit

It should be noted that even if imbalances have occurred continually that
are so large that the comparison is made with limit value 4, and the
imbalance suddenly drops below limit value 1, full extraction speed will be
executed.
The distribution time programmed into the drain module does not count
down during the time imbalance measurement is in progress. The
countdown only starts when an approved imbalance value has been
achieved.
In the event that an approved imbalance value is never achieved, the drain
sequence is interrupted, any subsequent extraction is skipped and the next
washing sequence in the washing programme will be executed.
Note that the imbalance measurement is always carried out if the
distribution rpm has been programmed in a drain module. In other words,
irrespective of whether the drain module is followed by extraction or not. If
a drain module is not followed by an extraction, it is necessary to avoid
programming the drain module with distribution rpm as the imbalance
measurement will then be carried out. This takes time, approximately 40
seconds in the best case scenario, although in the worst case scenario, if
limit value 4 has to be used, it can take several minutes.

• Door lock A41 that contains
- an actuator that locks the door lock and
which 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.
- micro switch S3 that is closed when the
door is closed.

• Door lock control A31 that is situated in the
front control unit of the machine. This card
controls the door lock function and whether
the drum is empty and not rotating. It locks

When the door is closed (closed door lock
switch S3), the programme unit may request
door locking by applying a voltage of 200240 V on door lock controller A31 input X92.
The following check is made by the A31 card
prior to locking of the door:

• Drum not rotating - pulse frequency on
input X95 from rotation sensor B3 less than
0.4 Hz.
When the above conditions are met, the card
A31 outputs a closing pulse on output X96 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:

controller.
The following check is made prior to unlocking of
the door:

When the above conditions are met, the door
lock controller outputs an opening pulse on
output 96 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

When the green LED on the motor control card is lit, the components carry dangerous voltages.
The motor control lose all voltage about 10-30 seconds after the

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.

38. Drain valve
1
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
• Rubber diaphragm with drain connection
• Upper part with connection for outer drum
Function
Fig.
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.

Calibrating the weighing equipment
The “Zero calibration” function is used to increase the accuracy of the
weighing equipment. This should be done once a month. See the section
headed “Zero calibration” under “Machine operation”.
If a new scale unit is installed, it must be calibrated as described in the
section ”Calibrate the scale” under ”Machine operation”.
Checking accuracy of weighing equipment display
Twice a year you need to check that the weighing equipment is displaying
the accurate weight, with the aid of an object of known weight. If the
weighing equipment does not show the real weight of this object, you will
need to follow the “Zero calibration” procedure, a function in the Clarus
software. Follow the instructions under “Zero calibration” in the “Machine
operation” section of the manual. If this is unsuccessful, the weighing
equipment will have to be recalibrated using the “Calibrate the scale”
function, as described under “Machine operation”.
If the weighing equipment has a fault
Follow the troubleshooting procedure under the heading “Fault-finding,
weighing equipment”.
If you cannot rectify the problem with the help of that section, make a note
of the weighing equipment version number before you contact the service
department.
To find the weighing equipment version number, access the service
program, select “Scale adjustments”, then “Read version number”.

• If more than one load cell is faulty, the faulty cells can be identified using
a multimeter on the scale unit weight-totalling board to check each cell in
turn, as follows:
- Remove the four screws on the scale unit cover.
- Check that the four load cell cables are connected to the scale unit.
- Measure the voltage at the connectors on the weight-totalling board,
between terminal 2 and 3 for each load cell. The normal value for an
unladen machine is approx. 3-5 mV (DC). A value different from this
indicates that the load cell is faulty.

Possible causes:
The option “DISPLAY WEIGHT ALLOWED” may be switched off (have the
answer “No” alongside) in “Settings 1”. Possible fault in communication
with CPU board or display. The fault can also be in the scale unit.
Fault-finding procedure:
• Check in “Settings 1” that the option “DISPLAY WEIGHT ALLOWED”
has “Yes” alongside.
• Check that the cables/wiring for CPU communication and power supply
are connected to the scale unit and in good condition.
• If the washer extractor appears to be working normally apart from the
absence of weight parameter display, try replacing the scale unit as
described under “To replace the scale unit”.
If you suspect that the weighing equipment is not displaying accurate
weight value.
Probable cause:
Probably a faulty load cell.
Fault-finding procedure:
• Place an object of known weight at one corner on top of the washer
extractor. Check the weight shown on the display. Move the weight to
each of the other corners of the machine in turn, checking the display
each time. If one corner is different from the others, this will reveal
which load cell is faulty.
• Check that the load cell in question is mechanically unobstructed, free
of anything which could affect its normal functioning.
• Replace the load cell as described under “To replace a load cell”.
