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 EWX11831 and
EWX14931 electronic control system (SERIES 7/8/9).
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 (EWX11831 and EWX14931 platform) use a heating element
with thermal fuses (inside its branches) for safety, which interrupt in case of temperature overload caused by the
water level dropping 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
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.
“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.
“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 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.
You have to unplug the appliance to cut off the power supply
“Zero Watt”mode
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.

2 WARNINGS
Any work on electrical appliances must only be carried out by qualified personnel.
Before carrying out work on the appliance, use suitable instruments to check that
the power supply system in the house is fully efficient. For example: refer to the
indications provided/illustrated in the <<metratester>> course at the address
(http://electrolux.edvantage.net) on the Electrolux Learning Gateway portal.
On completing operations, check that the appliance has been restored to the same
state of safety as when it came off the assembly line.
If the circuit board has to be handled/replaced, use the ESD kit (Cod. 405 50 63-95/4)
to avoid 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 not fitted with an ON/OFF switch. Before you access internal
components, take the plug out of the socket to cut the power supply.
Make resistance measurements, rather than direct voltage and current
measurements.
Warning the sensors located on the display board could be at a potential
of 220 Volts.
When replacing the heating element, replace it with one that
has the same characteristics (2 thermal fuses) in order not
to compromise the safety of the appliance. NEVER remove/
switch the NTC sensors between heating elements.
Always empty the appliance of all the water before laying it
on its side (see the relevant paragraph).
Never place the appliance on its right side (electronic control system side):
some of the water in the detergent dispenser could leak onto the electrical/
electronic components and cause these to burn.
When replacing components, please refer to the code shown in the list of
spare parts relating to the appliance.
Do not place any kind of container under the appliance to catch any drips of water.

3.2.2.4 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 button 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.
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 keys.
The volume level is set in the factory and cannot be adjusted by the user.
When the buzzer is disabled (using the combination of keys) 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 by pressing key combination
(which may be silk-screen printed on the control panel or described in the instruction manual), but the alarm
signalling remains enabled.
