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 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
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.

Programme phases:
The three icons shown have the following meanings, respectively:
Wash/Prewash/Steam
Rinse
Spin
They are lit during the setting phase to display which phases are included in the programme.
During the programme the icon for the phase in progress flashes, and when the phase has ended it remains lit continuously. The same applies when the machine is in pause during the cycle. The Wash/Prewash/Steam icon also lights up during the steam phase, in appliances which feature this programme.
Padlock:
The icon lights up when the child lock is on. It indicates that all the buttons are disabled to prevent children from modifying, starting or pausing the cycle; Press any button or turn the selector dial during its activation and the icon will flash.
To enable/disable this function, a key combination needs to be pressed. It may be silk-screen printed on the control panel or described in the instruction manual.
Door closed sensor:
Lights up when the safety device stops door opening and switches off when the door can be opened. Flashes when the device is about to unlock the door.
Washing programme time:
This appears after a washing programme has been selected. This time corresponds to the time required for the maximum wash load for each type of programme. After the programme has started, the time decreases (and is updated) minute by minute.
Delayed start:
Selected using the related button. After the START/PAUSE button is pressed, the countdown starts and the delay time decreases hour by hour, from a delay of 20 hours up to 2 hours ( 30 60 90 2h 3h... 20 h 0h). During the last 2 hours, it decreases by 30 mins at a time.
During delayed start, the icon remains permanently lit.
Selection incorrect:
Displays the flashing message Err, for one second. Appears on selecting option that is incompatible with the programme selected, or when the selector is turned while a cycle is running.
The information described below also appears on the LCD:
Technical Support - DMM 13/106 599 77 23-65 Rev. 03

4.2.1.6 Weight sensor (where featured)
Series 8
Series 9
During the programme selection phase, the weight sensor can be enabled/ disabled by pressing a key combination as shown in the figure.
Appliances fitted with the weight sensor (inserted inside a shock absorber) are designed - thanks to the LCD display - to inform the user of the weight of the laundry inside the drum while at the same time suggesting the quantity of detergent to pour into the dispenser provided. For it to operate, the appliance needs to be turned on and in selecting phase with the door open. When the laundry is being placed inside the drum, the LCD displays the weight in kg with an accuracy of half a kilogram. The exact sequence to have the correct weight information is as follows: The appliance must be turned off and the drum must be empty. Turn the washing machine on, select the programme, choose the options, and if the door was closed on starting, open it. The LCD displays the maximum declared weight for the selected programme and 0.0 kg the weight of the laundry inside the drum (empty drum). At the same time the laundry is placed in the drum, the LCD display updates the digits relating to the time until the end of the programme.
In the event of an overload in a programme (Cottons), the LCD display will continue to show the maximum weight without warning that the load is excessive. Whereas in other programmes (Synthetics, delicates, special programmes and in particular the drying programmes) if the weight exceeds by only 1 kg or more, the symbol “MAX” will begin to flash, together with the weight of the maximum load allowed.
In some cases, you will have to take some laundry out so that the symbol MAX and the maximum weight allowed stop flashing and to guarantee optimum washing performance.
Once the laundry has been loaded, close the door, the LCD display cancels all the weight details and displays the quantity of detergent to be poured into the dispenser.
The representation consists of: a measuring cup, a number and the symbol for the percentage. The number displayed represents the percentage detergent to pour into the dispenser, considering 100% to be the quantity required for the maximum load for the chosen programme (value that remains fixed even in the case of an overload).
Once the detergent has been poured in, and the START/PAUSE button has been pressed, the washing cycle will begin. The information about the weight of the laundry and the percentage detergent disappears and will not be displayed again.
