1 PURPOSE OF THIS MANUAL
The purpose of this manual is to provide service engineers who are already familiar with the repair procedures
for traditional washing machines with information regarding washing machines fitted with the EWX13611
(P6-P3.0) and EWX11831 (P6-P3.0) electronic control systems.
Previous platforms (electronic/mechanical) used a safety pressure switch that checked the minimum water level
in the tub, below which the supply to the heating element was interrupted.
The current electronic appliances manufactured use a heating element with thermal fuses (inside its branches)
as safety, which interrupt if the water level drops below the minimum level permitted.
The incorporated NTC probe contacts have a 2.5 mm pitch.
The manual deals with the following topics:
General characteristics
Control panel and compatibility between washing programmes and options
Settings: Demo, Diagnostics
Alarms
Technical and functional characteristics
Access
1.1
Low consumption mode
In order to reduce electricity waste when the cycle is not running, the appliances on this platform are designed
to enter consumption reduction mode:
1.1.1 P6 P3.0 with universal mo to r (EWX13611)
“Stand-Off” mode
When the appliance is switched off at the ON/OFF button, it is in the “Stand-Off” or “virtual” off status. The LEDs
and the LCD screen are turned off and the buttons are disabled, although the main circuit board and certain
electrical components are electrically powered.
You have to unplug the appliance to cut off the power supply
“Auto-off” mode
If, after 5 minutes, during the programme selecting phase or after the end of the cycle, the appliance receives
no further instructions, it is automatically turned off (for energy savings in conformity with the standards on
energy consumption).
All the settings are stored so that when the appliance is turned back on, the programme is ready or if the autooff mode was triggered after the end of the cycle, the user can see that the cycle ended normally, and can
restart it if necessary.
You have to unplug the appliance to cut off the power supply
If an alarm goes off when a wash programme is running, the automatic turn off is disabled showing the alarm.

1.1.2 P6 P3.0 with three-phase motor and Inverter (EWX11831)
Some appliances are fitted with a circuit (in the main circuit board) called Zero Watt (0 Watt with an actual
consumption
~
50 mW) which cuts off the power supply to the appliance:
a. When you press the ON/OFF button to turn off the appliance, the Zero Watt circuit is triggered and cuts off
the supply voltage after a few seconds, just long enough to secure the washing machine (motor off, door
locked, etc…), the cycle and any options selected are reset, so that the next time the appliance is turned on,
it is ready to perform the programme.
(To open the door, you will have to wait one or two minutes for the door safety lock to be released.)
b. If, after 5 minutes, during the programme selecting phase or after the end of the cycle, the appliance
receives no further instructions, it is automatically turned off and the Zero Watt circuit which cuts off the
supply voltage is triggered (for energy savings in conformity with the standards on energy consumption).
All the settings are stored so that when the appliance is turned back on, the programme is ready or if the
auto-off mode was triggered after the end of the cycle, the user can see that the cycle ended normally,
and can restart it if necessary.
If an alarm goes off when a wash programme is running, the automatic turn off is disabled showing the alarm.
The appliances which are not equipped with the Zero Watt (0 Watt) circuit in: “Stand-Off” or “Auto-off” mode,
see para. 1.1.1.

2 WARNINGS
Any work on electrical appliances must only be carried out by qualified personnel.
Before carrying out wo rk on the appliance, use suitable instruments to check that
the power supply system in the house is fully efficient. Fo r exampl e: ref er to the
indications provided/illustrat ed in the <<metratester>> co urse at the address
(http:// electrolux.edvantag e.n et ) on the Elect rolux Learning Gateway portal.
On completing operations, check that the applian ce has been rest ored to the same
state of safety as when it came off the assembl y li ne.
If the circuit boar d has t o be han dled/rep laced, use t he ESD k it (C od. 405 50 63-95/4) to av oi d
static electricity from damaging the circuit board, see S.B. No. 599 72 08-09 or consult the
course <<Electrostatic charges>> at the address (http://electrolux.edvantage.net) on the
Electrolux Learning Gateway portal.
This platform is no t fitted wit h an ON/OFF switch. Before you access int ernal
components, take th e plug out of the socket t o cu t the power su pp ly.
Make resistance measurements, rather than direct vol t age and current measurements.
Warning the senso rs lo cat ed in the di splay board could be at a potential of 220 Volts.
When replacing the heatin g element, replace it with one th at has
the same characterist ics (2 thermal fuses) in order no t to
compromise the safety o f the appliance. NEVER remove/switch
the NTC sensors betw een heati ng elemen t s.
Always empty the appliance of all the water before laying it on its side
(see the relevant paragraph).
Never place the appli ance on its rig ht side (electronic control syst em sid e) :
some of the water in the deterg ent di spen ser cou ld leak onto the electrical/electronic
components and cau se these to bu rn.
When replacing components, please refer to the code shown in th e list of spare parts
relating to the appli ance.
Do not place any kind of container under the appliance to catch any drip s of wat er.
Make sure you wear gloves, becau se parts of the cabinet are sharp.

3.3.2 Control panel configuration
The washing programmes and the functions and the various touch sensors vary according to the model,
since these are determi ned by the configuration of the appli ance.
3.3.2.1 Programme configuration
The table below lists the parameters that can be used to define the washing programmes.
Types of fa br ic
Cotton/linen, Synthetic fabrics, Delicates, Wool, Hand-wash,
Shoes, Jeans, Duvet, Silk.
Special programmes
Cotton/linen + pre-wash, Soak, Miniprogramme, Easy-Iron,
Conditioner, Rinse, Drain, Spin, Economy.
Temperature
Normal, Minimum, Maximum: the initial temperature is the one
proposed for the washing programme.
Spin
Normal, Minimum, Maximum.
Options (Normal/Possible)
Rinse Hold, Pre-wash, Extra rinse, Easy-Iron, Economy (energy
label), Normal, Super quick, Reduced spin speed, No spin.
Programme phases
Pre-wash, Wash, Rinses, Spin, Delayed start.
3.3.2.2 Sensors – LEDs
The function of each touch sensor is defined via the configuration of the appliance (the data and images are for
guidance only).
The touch sensors are positioned under the silk-screen printed symbols on the control panel (circled here in red).
A light touch on the centre of the symbol is enough to activate/deactivate the function linked to the sensor with
the switching on/off of the relative Led confirming that the enabling/disabling has taken place.
At the same time as the enabling/disabling of options, the cycle duration time is updated via the digits (styling
P3.0 only).
You need to keep your finger pressed down for a longer period of time with the Start/Pause sensor to confirm
both the cycle’s start and pause, in order to avoid unwanted starts or accidental pauses.

Every time you touch a sensor, you need to lift your finger up by a centimetre and half a second needs to
elapse before touching it again, otherwise the electronic system does not recognise that the sensor has been
touched for a second time.
The sensors used for adjusting the: Temperature, Spin, delayed Start and Time Manager have a continued
variation of values as long as your finger is in contact with the sensor.
3.3.2.3 Buttons – Sensors – LEDs
Button no. 1: ON/OFF – ON
Press it to turn the appliance on, at the same time the buzzer will sound a tone (if enabled), the LEDs of the first
four touch sensors (S1÷S4) will light up from the bottom up, then the LEDs relating to the following will stay on:
the main programme, the recommended spin speed and temperature.
The operation of the ON/OFF depends on the configuration of the main circuit board.
It can cut the appliance off from the electricity mains completely (0 Watt circuit) or
set the appliance to low energy consumption mode (without 0 Watt circuit) in which
case you will need to take the plug out of the socket to cut off the electricity supply
completely.
Press the ON/OFF button to cancel the chosen programme.
To switch the appliance off, hold down the button for 1 second, at the same time the
buzzer will sound a tone (if enabled), all the LED will switch off, all the options
selected and any programme that is running will be cancelled.
Sensor no. 1: PROGRAMMES
The programmes are associated with the second sensor, combined with eight LEDs (L1÷L8).
As soon as the appliance is switched on, the first LED at the top corresponding to the
main programme lights up.
To the left of each LED, there is a description of the programme and each time the sensor
is touched, the LED underneath it lights up, so the programme selection occurs from the
top down; once the last programme has been reached, if you touch the sensor again, the
selection returns to the top, i.e. the initial programme.
The selected programme is shown by the LED beside the description silk-screen printed
on the control panel lighting up.
For a quicker selection, hold your finger down on the sensor for longer.
Sensor no. 2: TEMPERATURE
The temperature is associated with the second sensor, combined with five LEDs (L9÷L13).
The initial temperature displayed is that set for the chosen programme.
By touching the sensor you can lower the temperature. Once this has been reached the
selection starts again from the highest available one for the selected programme.
The selected temperature is shown by turning on the LEDs near the silk-screen printed
value on the control panel.
The temperatures available are: 90 °C, 60 °C, 40 °C, 30 °C, cold cycle.
The initial temperature set for each programme is configurable;
For a quicker selection, hold your finger down on the sensor for longer.

Sensor no.5: START/PAUSE
This sensor has the START/PAUSE function, used to start up a washing programme,
after selecting the washing cycle and required options; it can also pause a cycle that
has already started: to allow you to change selected option or open the door (if the
temperature conditions or water level allow for this).
The cycle re-starts if you touch the sensor again.
The (L24) LED combined with this sensor flashes slowly: in the selection phase, during
the pause and at the end of a cycle with water in the tub.
It stays lit when a cycle is running and turns off when the cycle has ended and the door
is unlocked.
While other sensors when touched immediately change from selected to de-selected,
in the case of this sensor, more time is needed to avoid unwanted cycle start ups
or pauses.
In the event of an incorrect selection by the end user, such as: an option that is not
compatible with the selected programme or that has been made after the programme
has commenced, this is indicated by three quick red flashes. The same LED is used to
notify the user of any specific problems with the appliance. The buzzer does not play
any particular tune.
Sensor no.6:- DELAYED START (configurable)
This sensor works as the DELAYED START and it is combined with the three
LEDs (L25÷L27) that surround it.
Touch it in sequence to choose from one of the three delayed start options: 3 h6 h-9 h with the related LED coming on.
In order to reset the delay time, reach the maximum delay time and the next time
the sensor is pressed the delay time is cancelled and no LED is lit up, or if the
delayed start has already been set, put the appliance on PAUSE and reset the time
as described earlier.
Indicator LEDs
In addition to lighting up when their functions have been enabled, in combination with the red
LED of the START/PAUSE sensor, they notify the end user of any specific problems with the
appliance that may be solved without having to call for technical assistance (see page 26).
Padlock:
When the related LED (L28) is lit, it indicates that all the sensors are disabled to prevent
children from altering, starting or pausing the cycle.
When enabled, touch any sensor and the LED flashes three times to remind the end user
that the appliance is locked.
Use the combination of two sensors (touch for approximately 5 seconds) illustrated in the figure below to
enable/disable this option.

Extra Rinse:
When the related LED (L29) is lit up, this indicates that the option is enabled (it lights up during
the washing and rinse cycles, and it remains switched off during the drain and spin cycle).
The option remains enabled even after the appliance has been turned off (for subsequent
programmes).
Use the combination of two sensors illustrated in the figure below to enable/disable this option.
Door loc k :
When the related LED (L30) is lit up, the safety device prevents the door opening and
switches off when the door can be opened.
Flashes when the device is about to unlock the door (with door interlock with PTC,
which needs one/two minutes to open).
3.3.2.4 Buzzer
This comprises a multi-tone buzzer and sounds in the following cases:
When the machine is turned on and off it emits two different tunes.
When a sensor is pressed it emits a short “Click”
When the cycle ends this is indicated by a special sequence of “three long beeps” repeated at intervals of
15” for a total of 2 minutes. The sequence can only be stopped by opening the door in appliances where the
instant door safety device with micro-switch is fitted.
In the event of a malfunction in the machine this is indicated by a special sequence of “three short beeps”
repeated 3 times at intervals of 15” for a total of 5 minutes.
All appliances are fitted with the buzzer, and leave the factory with the option enabled. To disable it use the
combination of sensors.
The volume level is set in the factory and cannot be adjusted by the user.
When the buzzer is disabled (using the combination of sensors) it only emits the short “Click” and the sequence
of “three short beeps” when an alarm is triggered.
During the programme selection phase, the buzzer can be enabled/disabled with a sensor combination (which
may be silk-screen printed on the control panel or described in the instruction manual), but the alarm signalling
remains enabled.
To enable it, touch the sensors simultaneously for 3 seconds. A short beep will confirm that it has been
enabled, whereas two short beeps will confirm that it has been disabled.

Sensor no .6 : THE CYCLE FINISHES IN (Finish In)
This sensor allows the end user to programme in how many hours’ time the
washing cycle will finish.
In detail, the cycle start can be delayed so as to have the cycle end at the desired time.
You can select from a minimum of 3 hours to a maximum of 20 hours.
The first time you press the sensor, the display indicates 3 hours and the related
LED (26) lights up to indicate the option is enabled. The next time you press it,
the time increases by 1 hour, up to a total of 10 hours. The increase is of 2 hours
every time you press the button for the range between 10 and 20 hours.
If the display indicates 20 hours, the next time you press the sensor, “Finish In”
will be disabled and the washing cycle time will be displayed and the LED (26)
will switch off.
For a quicker selection, hold your finger down on the sensor for longer.
Setting an option after selecting “Finish In”
“Finish In” must be enabled after an option has been selected (if necessary) and before you start the cycle. If
the end user, after setting “Finish In”, modifies the programme settings, “Finish In” will be disabled, the LED (26)
will flash once and the display will once again indicate the washing cycle time.
“Finish In” after touching the START sensor
Once you have selected the programme and the option (if necessary) and set “Finish In”, the washing cycle
starts when you touch the START sensor; the appliance door is locked and the countdown begins, and is
indicated on the display at one-hour intervals until the start of the washing cycle. Once the “Finish In” time is up,
the display indicates the amount of time necessary to perform the washing cycle, starting the countdown of the
cycle with one-minute intervals, until the end of the cycle.
If the appliance is paused during the countdown of the “Finish In” option to change the option and including “Finish
In”, the delay time is deleted and “Finish In” is disabled; touch the sensor and the display will indicate “error”.

5 DEMO MODE
A special cycle is designed to demonstrate the operation of these appliances in shops, without connecting them
to the water mains. This way, any one of the programmes can be selected and, once the start button/sensor
has been pressed/touched (START/PAUSE), the appliance will only perform some of the phases of the
programme, skipping those which cannot be performed (water fill, drain, heating).
The cycle takes place as follows:
The door lock is enabled as usual (door locked during operation, possibility of opening it at the end of the
cycle or when paused).
Motor: all low speed movements are enabled, the pulses and spin are disabled.
The water fill solenoid valves and the drain pump are disabled.
Display: as the cycle phases are very fast (one second in the demo cycle corresponds to approximately one
minute in the actual cycle) the end time decreases by 1 unit per second. Bear in mind that the end time
does not always correspond to the actual cycle time.

7.2.5 Rapid reading of alarms
It is possible to display the last alarm even if the selector is not in the eleventh diagnostics position or the
machine is in normal operation (e.g. while a washing programme is in progress):
→ Touch the START/PAUSE sensor and the nearest option sensor simultaneously (as if you were entering
DIAGNOSTIC mode) and hold for at least 2 seconds: the LCD display shows the last alarm.
→ The alarm will continue to be displayed until a sensor is touched.
→ The alarm reading system is as described in para. 7.2.
→ While the alarm is being displayed, the appliance continues to perform the cycle or, if in the programme
selection phase, it stores the previously selected options.
7.2.6 Deleting the last alarm
It is good practice to cancel the alarms stored:
after reading the alarm codes, to check whether the alarm re-occurs during the diagnostic cycle
after repairing the appliance, to check whether it re-occurs during testing
N.B. With this operation all the alarms stored are deleted.
P3.0 P6
Enter the diagnostic mode (para. 6.1).
Using sensor S1, select the position in which the LED lights up to display the alarms.
Simultaneously press the START/PAUSE sensor and the nearest option sensor (as shown in the diagram).
Keep your finger above the sensors (for approximately 5 seconds) until for styling P3.0 the display shows
“E00”, while for styling P6 the START/PAUSE LED stops flashing.
