been selected, the countdown will begin and the display will indicate it. The LED stops flashing and
remains lit for the whole duration of the programme.
Pause: by pressing the button again, the current programme is interrupted and the display or the
corresponding LED starts flashing. During the pause phase it is possible to open the door only if the
machine is not during the heating phase, the water level is not high and the drum is not moving.
During the pause it is possible to modify the programme as follows:
- the OPTIONS of the cycle can be modified before the phase by which they have to be performed
- the SPIN can be modified before the final spin
To re-start the programme press the START/PAUSE button again.
4.5
Functions of the buttons
The washing programmes and the functions of the single buttons vary for the different models, since
they are determined by the configuration operation of the appliance.

ª This option cannot be selected for DELICATES, WOOL and HAND-WASH cycles.
ª The movements during the washing phase change from vigorous to normal.
5.3.6 Short (daily)
ª Modifies the structure of the washes in the COTTON and SYNTHETICS programmes in order to obtain
good washing performance with a very short cycle (optimization for small loads).
5.3.7 Very short
ª Modifies the structure of the COTTON, SYNTHETICS and DELICATES programmes in order to obtain
short washing times (optimization for small or lightly-soiled loads).
ª Reduces the number of rinse cycles (one less).
ª Increases the water level in the remaining two rinse cycles.
5.3.8 Economy / Energy label
ª Modifies the structure of the COTTON 40°/50°/60°/90° - SYNTHETIC FABRICS 50°/60° programmes in
order to reduce energy consumption.
ª Reduces the washing temperature in 90°/60°/50° programmes, while for the 40° programme the
temperature is increased by 4°.
ª Increases the duration of the wash phase.
5.3.9 Sensitive
ª Adds a rinse in the COTTON – SYNTHETIC FABRICS.
ª During the cotton cycles the movements pass from vigorous to normal.
ª Eliminates the intermediate spins except from the last two which are reduced.
5.3.10 Extra rinse
Adds two rinses in the COTTON, SYNTHETICS and DELICATES cycles.
Eliminates the intermediate spin cycles, with the exception of the last rinse, which is reduced to 450 rpm.

ª Modifies the structure of the COTTON - SYNTHETICS– DELICATES programmes to obtain washing
time very short (optimization for small or lightly-soiled loads).
ª Reduces the no. of rinses (one rinse less).
ª Increases the water level of the other two rinses.
ª Corresponds to the SHORT- VERY SHORT cycles on the basis of the configuration of the appliance.
5.3.18 Temperature adjustment
ª Used to select the washing temperature compatibly with the limit temperature for the cycle.
ª Can be used during the cycle selection phase: the temperature can be modified only if the heating phase
has not started (in pause mode).
5.3.19 “Exclusion of the buzzer”
In models with the buzzer it is possible to exclude
the acoustic signal during the selection or at the
end of the cycle, but the alarm remains on.
ª Press buttons no. 1 and no. 4 (or no. 5)
simultaneously to deactivate the buzzer for 2
seconds; this option will be memorised until it
will be deactivated with the same procedure.
5.3.20
Delayed-start time
• Models with digit
ª It is possible to select, during the programme selection phase, a delayed start from 30 minutes up to 23
hours () 30’) 60’) 90’) 2h) 3h...) 23h) 0h).
ª During the delay phase, the time decreases every hour up to 2h, then by 30minutes.
ª To start the cycle immediately, after the delay time began: press the Start/Pause button, cancel the
delay time by pressing the relative button and press Start/Pause again.
• Models with led
ª Insert a pause before the start of the programme, the delay time is indicated by the corresponding LEDs.
ª To start the cycle immediately, after the delay time began: press the Start/Pause button, cancel the
delay time by pressing the relative button and press Start/Pause again.

Display (some models)
The display shows the following information:
Ö three flashing digits, when the appliance is switched on.
Ö the duration of the washing programme, which appears after selecting it. This time corresponds to
that necessary for the maximum load for every type of programme. After starting the programme, the
time diminishes (and updates) by every minute.
Ö the end of the programme indicated by a "0" (when it is possible to open the door).
Ö the delayed start, selected by the relative button. After pressing the START/PAUSE button, the
countdown starts and the delayed time diminishes by every hour. In the last 2 hours diminishes by
30min.
Ö an alarm code, indicating anomalies in the functioning of the machine.

Control of water level in tub
The water fill is carried out in two phases:
• level fill: is controlled by the closure of 1st level pressure switch in full position
• time fill: the duration is calculated by the electronic to fill the set quantity.
The different levels are determined by the model configuration and depend on the type of tub used.

MAIN CIRCUIT BOARD
Ö The circuit board receives signals relative to the cycle settings via the control/display board. The buttons,
the LEDs and the display are also mounted on this board which is connected to the programme selector.
Ö The board also powers all the electrical components (solenoid valves, washing motor, drain pump,
heating element, door interlock).
Ö The board controls the temperature of the washing water via an NTC sensor, as well as the speed of
rotation of the washing pump according to the signal received from the tachometric generator.
Ö It checks the water level in tub via the level pressure switch and the safety one.

Configuration of

Description of the
cycle
The main circuit board features an EEPROM memory (external to the microprocessor) which stores in
memory data relative to the configuration, description of the cycle, cycle status in case of a power failure,
and any alarm conditions.
The configuration data (entered in the factory using a computer with a DAAS interface) determine the
functionalities of the appliance (number and type of programmes, options, LEDs etc).
The overall structure of the microprocessor memory on the main PCB is subdivided into three sections:
ROM
This area of memory contains the software with the general instructions that control the operation
of the appliance, such as those of the electrical components and alarms. The ROM is set up by
the manufacturer of the microprocessor, and cannot be modified.
RAM
This part of memory contains all the variables used during the execution of the wash programme,
which are written in dynamic format. The RAM can be read using a DAAS interface.
EEPROM This area of memory contains:
→ the data necessary to restart the appliance in case of a power failure;
→ the parameters for the wash cycle, such as water fill level, speed and type of motor movement,
and the temperature during the various phases of the wash cycle. Once written, this data is
protected and, normally, can be read only using a DAAS interface;
→ data relative to the configuration of the appliance, such as the speed of the final spin phase,
the volume of the tub, the type of washing system, etc. This data may be entered either via a
DAAS interface or via the control/display board.
7.2
Power supply and programme selection
The main board (3) is powered by the
interference suppressor (1) and by the
closure of the contacts of the main switch
(2). The affected connectors are J6-2
(neutral) and J10-1 (line).
The control/display board (4) is powered at
5V by the main board: through the
programme selector (5) it is possible to
select the programme. The selection of the
options / start is performed through the
board buttons (4).
The buzzer (if featured) (6) is powered by
the display board.
7.3
Door interlock
There are two types of door interlock:
• voltmetric with PTC: it is always necessary to wait from 1 to 3 minutes before opening the door.
• instantaneous: the door can be opened as soon as the cycle ends.
7.3.1
Voltmetric interlock with PTC
1. Suppressor
2. Main switch (button or
programme selector)
3. Door interlock
4. Main PCB
5. Door pilot lamp closed
• Operating principle
ª When the washing programme is started by pressing the START/PAUSE button, the bi-metal PTC
(contacts 3-5) is powered by the triac on the PCB (J6-2 connector): after 2 – 4 seconds, this closes the
switch (5-4) which powers the electrical components of the appliance (only if the door is closed).
ª The door interlock prevents aperture of the door while the appliance is in operation.
ª At the end of the washing programme, the PCB disconnects the interlock from the power supply, but the
door remains locked for 1 to 2 minutes (PTC cooling time).
Door locked” pilot lamp
ª Certain models feature a pilot lamp which lights to indicate that the door is locked. This pilot lamp
switches off when the door can be opened.
7.3.2
Instantaneous door interlock
1. Suppressor
2. Main switch (button or
programme selector)
3. Door interlock
4. Main PCB
5. Door pilot lamp off
• Operating principle
ª When the appliance is switched on, the ON/OFF switch closes and the bi-metal PTC (contact 4-2) is
powered; the door, however, is not locked.
ª When the programme starts (START/PAUSE button), the PCB transmits a 20 msec voltage signal to
contacts 4-3 of the solenoid valve (J10-2 connector of the board) (at least 6 seconds must elapse after
switching on); this signal locks the door and, at the same time, closes the main switch (contacts 4-5)
which powers all the components in the appliance.
• At the end of the programme, the PCB transmits two 20 msec signals (at an interval of 200 msec).
- the first signal does not release the door.
the second signal (which is transmitted only if the system functions correctly) releases the door
interlock and at the same time the contacts of the main switch are opened.
•
ª
-
Conditions necessary for door release
Before transmitting the door release signals, the main PCB checks for the following conditions:
the drum must be stationary (no signal from the tachometric generator)
the water level must not be higher than the lower edge of the door
the temperature of the water must not exceed 40°C.
• Automatic release device
ª In the event of a power failure, if the appliance is switched off, or if the solenoid should malfunction, the
bi-metal PTC cools over a period of 1 to 4 minutes, and then releases the door.
• “Door locked” pilot lamp
ª Certain models feature a pilot lamp which lights to indicate that the door is locked. This pilot lamp
switches off when the door can be opened.
7.4
Control pressure switch for water level in the tub
Control of the water level is performed by a two or three-level pressure switch which functions as follows:
•

Phase A:
The phase during which the initial fill takes place:
1. Water fill until the anti-boiling pressure switch closes on FULL.
2. Water fill until the 1st level pressure switch closes on FULL: the delivery of the solenoid is
calculated during this phase.
3. Water fill for time Q, which varies according to delivery and cycle phase.
Phase B:
If the 1st level pressure switch returns to EMPTY, a supplementary fill is performed until the
pressure switch returns to close on FULL. This phase may be followed by a further timercontrolled fill.

to the EMPTY position.
7.9
Water Control (not in all models)
The Water Control system is a sensor located in contact with the base frame. The sensor detects water leaks
inside the machine (not only during normal operation, but also when the unit is off and plugged in) and starts
the drain pump.

Water Control
Besides supporting the various components on the appliance (drain pump, recirculation pump, shock
absorbers, etc.), the base frame is designed to be a container that collects any water leaks that may occur
(from the tub, from a tube or pipe, etc.). These leaks are directed into an area where a float is installed.
When this float is raised by water, it actuates a microswitch that starts the drain pump. When the switch is
tripped, an alarm is also signalled (if the machine is switched on).
Important: When replacing the drain pump or tube, arrange
the tube so that it doesn’t interfere with the float.

7.12 Power supply to motor
The PCB powers the motor via a triac. The direction of rotation is reversed by switching of the contacts on
the two relays (K2-K3), which modify the connection between the rotor and the stator.
In certain models (1200-1600rpm), a third relay (K4) is used to power the stator (full or half field) according
to the spin speed
The speed of rotation of the motor is determined by the signal received from the tachometric generator.
During the spin phases, the microprocessor, depending on the software configuration, may perform the antifoam control procedure (if featured) and the anti-unbalancing control procedure.
7.13 Anti-foam control system
The anti-foam control procedure (if featured) is performed via the anti-boiling pressure switch (AB).

Spin
FUCS
Spin with little foam: if the contact of pressure switch AB closes on FULL, the spin phase is
interrupted; the drain pump continues to operate and, when the contact returns to EMPTY, the spin
phase is resumed.
Spin with excessive foam in the tub (critical situation): The control system detects whether the
pressure switch commutates 5 times to FULL. In this case, the spin phase is skipped, and a one-minute
drain cycle is performed with the motor switched off; in the case of a washing phase, a supplementary
rinse is added.
7.14 “FUCS” (Fast Unbalance Control System)
rpm
The control procedure for unbalanced loads is performed dynamically, before each spin cycle, as follows:
ª The phase begins at a speed of 55 rpm; the speed can never fall below this threshold, otherwise the
check is repeated.
ª At intervals of 300 ms, the balance is calculated and compared with predetermined limits. If the value is
less than the lower limit, the speed of the drum is increased by a certain value depending on the
transmission relation between motor pulley/drum; if the unbalancing is higher, it is decreased by the
same value. The reduction in the speed of the drum distributes the washing correctly; this procedure is
repeated until the wash load is completely balanced.
ª Correct balancing of the wash load is achieved at a speed of 115 rpm, after which the spin cycle begins.
Real speed
Selected speed
The Unbalancing Control function takes place in different phases: each phase is characterized by:
ª an unbalancing index (0-1-2-3)
ª an unbalancing threshold value (ex: 350, 650, 850, 1200rpm)
ª a time out (max. time)
• Ending of the FUCS balancing phase
The phase is ended when:
ª The drum rotation speed is 115 rpm (or 85rpm in some cases of unbalancing index). In this case the
spin is performed.
ª In some cases the optimal balancing value is not reached: a reduced spin is performed depending on
the unbalancing.
ª In the worst case, in which all phases are not sufficient to reach a minimum balancing value, the spin is
not performed.

8 DEMO Mode
A special cycle has been created for demonstration of the operation of these appliances in retail outlets
without connecting the appliance to the water supply. In this way, the salesman can select any programme;
after starting the cycle by pressing START, the appliance will perform certain phases only, and will skip
those which cannot be performed (water fill, drain, heating).
The cycle takes place as follows:
ª the door locking device is actioned in the normal way (i.e. the door remains locked while the appliance is
in operation, and can be opened at the end of the cycle or in pause mode)
ª motor: all low-speed movements are enabled, while the pulse signals and the spin cycle are excluded
ª the water fill solenoids and the drain pump are disabled
ª display: since the phases of the cycle take place in rapid succession (1 second of the demo cycle is
equivalent to 1 minute of the actual cycle), the time-to-elapse decreases by 1 unit per second.
Remember that the time-to-elapse does not always correspond to the actual cycle time
ª alarms: for reasons of safety, the following groups of alarms remain enabled: E40 (door closed), E50
and E90 (communication between the boards/configuration).
8.1
Demo mode setting
ª Switch the appliance off
ª Press buttons 1 and 5 simultaneously and then, holding them down, switch the appliance on by rotating
the programme selector of two positions clockwise
ª Hold buttons 1 and 5 down until the LEDs start flashing (about 5 seconds).
8.2
Exiting demo mode
ª To exit demo mode, switch the appliance off.
9 DIAGNOSTICS SYSTEM
9.1
Access to diagnostics system
Using a single procedure, it is possible to access to the diagnostics system. After accessing this function, the
following operations can be performed:
ƒ control of the operation of each of the components in the appliance
ƒ read / cancel the alarms
The diagnostics cycles are available only if the communication between the main PCB and the display board
is correct; moreover there should not be configuration errors of the appliance.
To access:
1. Cancel the set programme and switch the appliance off.
2. Press buttons 1 and 2 simultaneously and then, holding them down, switch the appliance on by rotating
the programme selector of one position clockwise.
In the first position the function test of the buttons and the corresponding LEDs is performed; by rotating the
programme selector clockwise the operation diagnostics of each component and the reading of the alarms
is carried out.
9.2
Exiting diagnostics system
ª To exit the diagnostics system switch the appliance off, on and then off again.
9.3
Phases of the diagnostics test
Independently of the type of selector, after activating the diagnostics system, the operation diagnostics of
the different components and the reading of the alarms can be performed, by rotating the selector
clockwise.
In models with digit the code of the selector position is displayed for a second.
In the diagnostics cycle all alarms are activated. If during the cycle operation an alarm occurs, the appliance
blocks and the LEDs (and the display) flash indicating the relative code.

10 ALARMS
10.1 Displaying the alarms to the user
Control of the alarm system can be configured; according to the model, therefore, some or all of the alarms
may be displayed to the user.
Normally all the alarms are displayed to the user except for:
- E10 – water fill
- E20 – drain water
- E40 – door closure
- E90 – configuration
The alarms are active during the execution of the washing programme; except for the alarms relative
to the configuration and power/frequency supply which are displayed also in the selection phase.
The door can normally be opened (except where specified) when an alarm condition has occurred on
condition that:
• The level of the water in the tub is below 1st level
• The temperature of the water is lower than 55°C
Certain alarm conditions require that a drain phase be performed before the door can be opened:
• Cooling water fill if the temperature is in excess of 65°C
• Drain until closure of both pressure switch contacts (1st level and anti-boiling safety system) on EMPTY
within a maximum of 3 minutes.
10.1.1 Alarms displayed during normal operation
The type of alarm condition is displayed to the user by the repeated flashing of the END
OF CYCLE LED (0.4 seconds lit, 0.4 seconds off, with an interval of 2.5 seconds
between sequences). This LED is featured on ALL MODELS, though configured in
different positions.
If, for example, the user should forget to close the door, the
control system will detect alarm E41 about 15 seconds after the
start of the cycle; the cycle remains in PAUSE mode and the
display, if featured, would display E40.
Simultaneously the LED end-of-cycle flashes repeating the
sequence indicated in the table.
The four flashing indicate the first of the two digits of the alarm
E41 (the alarms relative to a same function are grouped by
families).
In this case, once the door has been closed, it is sufficient to
press the start button to start the programme.

10.2 Reading the alarm codes
In order to read the last alarm code memorized in the EEPROM on the PCB:
• Enter diagnostics mode
• Irrespective of the type of PCB and configuration, turn the programme
selector clockwise to the tenth position.
10.2.1 Displaying the alarm
The alarm is displayed by a repeated flashing sequence of the two LEDs (0.4
seconds lit, 0.4 seconds off, with an interval of 2.5 seconds between sequences).
The buzzer (if featured) will sound “bips” in synchronization with the flashing of
the LEDs.
• END OF CYCLE LED → indicates the first digit of the alarm code (family)
• START/PAUSE → indicates the second digit of the alarm code (number
within the family)
These two LEDs are featured on all models (though they are configured
differently), and flash simultaneously.
Notes:
• The first letter of the alarm code “E” (Error) is not displayed, since this letter is common to all alarm
codes.
• The alarm code “families” are shown in hexadecimal; in other words:
→ A is represented by 10 flashes
→ B is represented by 11 flashes
→ ...
→ F is represented by 15 flashes
• Configuration errors are shown by the flashing of a series of LEDs.
10.2.2 Examples of alarm displays
Example: Alarm E43 will display the following:
• On the display, if featured, E43
• The sequence of four flashes of the End-of-cycle LED indicates the first number E43;
• The sequence of three flashes of the Start/Pause LED indicates the second number E43;

10.2.3 Operation of alarms during diagnostics
All alarms are enabled during the components diagnostics phase. Moving the selector to pass from one
control phase to the other, the appliance exits the alarm condition and performs the selected phase (if the
alarm does not occur again).
10.3 Notes about some alarms
ƒ Configuration alarms
ª E91: the error is indicated by the flashing of all the LEDs, E90 is displayed on the display, if
featured
ª E92: the error is indicated by the flashing of the LEDs placed over the buttons, E90 is displayed on
the display, if featured
ª E93: the error is indicated by the flashing of the phase/warning LEDs, E90 is displayed on the
display, if featured
ª EB1-EB2-EB3 alarms: in case of problems with the power supply, the machine remains in alarm
condition till the frequency or the power supply voltage returns to correct values or the appliance is
switched off. “EB0” alarm family is displayed and it is not possible to enter the diagnostics or to use
“alarm fast display” mode: the alarm complete can be read only when the abnormal situation
terminated.
ƒ
E51- E52 alarms: during the diagnostics test all alarms are displayed: normally, moving the selector to
pass from one control phase to the other, the appliance exits the alarm condition and performs the
selected phase. This does not happen for the E51 alarms (motor power triac short-circuited) and E52
(no signal of motor tachometric generator): the only possibility to exit from the alarm condition is to
switch the appliance off.
10.4 Rapid reading of alarm codes
The last alarm code can be displayed even if the programme selector is not in the tenth position
(diagnostics) or if the appliance is in normal operating mode (e.g. during the execution of the washing
programme):
ª Press buttons 1 and 5 simultaneously for at least 2 seconds: the LED switch off and then display the
sequence of flashes indicating the alarm.
ª The alarm sequence is displayed for the time in which the buttons are hold down
ª The reading system is the same as that indicated in paragraph. 10.2
ª During the time the alarm is displayed, the appliance continues to perform the cycle or, if it is in the
selection phase, it keeps in memory the options previously chosen.
10.5 Cancelling the last alarm
It is good practice to cancel the last alarm, after reading the alarm code to check whether the alarm re-occurs
during the diagnostics control after the reparation of the appliance.
1. Select diagnostics mode and turn the programme selector to the tenth position (reading of alarm)
2. Press buttons 1 and 5 simultaneously.
3. Hold buttons 1 and 5 down (about 2 seconds).
