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 EWM/WD10931 electronic control system. Previous platforms (electronic/mechanical) used a safety pressure switch which controlled the minimum water level in the tub, beneath which the supply to the heating element was interrupted.
2 WARNINGS Any work on electrical appliances must only be carried out by qualified technicians. Before servicing an appliance, check the efficiency of the electrical system in the home using appropriate instruments. For example: refer to the indications provided/illustrated in the <> course at the address (http://electrolux.edvantage.net) on the Electrolux Learning Gateway portal.

3.1.4.3 Sensors 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.
3.1.4.4 Sensors – LEDs and LCD The functions of each button are defined by the configuration of the appliance. Button no. 1: ON/OFF – ON This button is always included in all three stylings. Press it to turn the appliance on, at the same time the buzzer will sound a tone (if enabled), all the LEDS around the selector dial will light up for an instant and the LCD display stays off (figure above).
Sensor no. 3: SPIN SPEED This is related to the part of the LCD display in which the washing cycle spin speed is shown. The starting speed shown on the LCD display is the one set for the programme selected.
LCD The information described below also appears on the LCD: Washing Machine The three icons shown have the following meanings, respectively: Wash 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. Padlock: The icon lights up when the “child lock” is on.
End of cycle: End of the programme is indicated by a permanently lit zero (when the door can be opened). Appliance stopping with water in the tub, at the end of Programmes with the RINSE HOLD option, this is displayed by a permanently lit zero. The LED indicating the door remains on and the LED of the START/PAUSE sensor is turned off. The washing machine continues to operate, rotating the drum once every 2 minutes. Alarm code: Indicates an anomaly during operation of the machine.
3.1.4.5 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 an appliance malfunction, this is indicated by a special sequence of “three short beeps” repeated three times at 20” intervals for 5 minutes.

Sensors – LEDs and LCD The functions of each button are defined by the configuration of the appliance. Button no. 1: ON/OFF Description: see Button no. 1 on page 14 Sensor no. 2: TEMPERATURE See description on page 14 The only difference from the TC3 version is the representation of the cold cycle, which is represented by the cold symbol by two dashes and S2 to replace the Digits. Sensor no. 3: SPIN SPEED This is related to the part of the LCD display in which the washing cycle spin speed is shown.
Sensor no. 11: STORING A PROGRAMME This sensor is located beneath the sensor used to adjust the spin speed, allowing the user to store or recall a customised programme. When the selected programme has been optimised with the desired options, it can be stored in the memory, by touching the related sensor for approximately 3 seconds. The buzzer “beeps” once, and simultaneously the LCD display shows flashing, to confirm the saving. This operation must be performed before you start the wash cycle.
LCD The information described below also appears on the LCD: Programme phases Padlock Door closed sensor Hot Water: It lights up when the possibility of filling water through the related solenoid valve is enabled. Washing programme time Delayed Start: Selected on the related sensor. After START/PAUSE or the sensor is touched, the countdown starts and the delay time decreases hour by hour, from a minimum delay of 2 hours to a maximum of 20 hours ( 30’ 60’ 90’ 2hrs 3hrs... 20h 0h).
Extra-rinse: Appliances which do not feature the sensor and related LED for the Extra rinse option can enable/disable this option by pressing a sensor combination (which may be silk-screen printed on the control panel or described in the instruction manual). This option is enabled/disabled during programme selection and is confirmed by the related symbol being turned on/off. The option remains enabled even after the appliance has been turned off (for subsequent programmes).
4.2.2 Time Manager and Eco Manager The Time Manager is an option available in programmes for Cotton, Synthetics and Delicates and it is teamed with the Eco Manager. During the washing programme selection phase, the icons shown below light up in the display, if the selected programme manages it. The Time Manager is represented on the right-hand side of the LCD display, and it consists of: eight segments surrounding the clock and three digits, which indicate the duration of the washing cycle.
4.2.2.1 Time Manager summary table This table shows: the Time Manager levels and the corresponding icon shown on the LCD display depending on the fabrics.
5 DIAGNOSTICS SYSTEM 5.1 Accessing diagnostics The operations listed below must be carried out within 7 seconds. TC3 TC2 Do not start the procedure with your fingers over the combination sensors 1. Switch on the appliance using the ON/OFF button. The first LED lights up. 2. Touch the START/PAUSE and the nearest option sensor simultaneously (as shown in the figure). 3. Hold your fingers over the sensors until the LEDs and symbols begin to flash in sequence (approximately 3 seconds).
5.3 Phases of the diagnostics test 5.3.1 TC3 – TC2 styling Irrespective of the type of PCB and the configuration of the programme selector, after entering the diagnostic mode, turn the programme selector dial clockwise to perform the diagnostic cycle for the operation of the various components and to read any alarms. Concurrently, a selector control code is shown on the LCD display, which indicates for two seconds the description in the last column of the table below.
8 9 - Door safety interlock - Wash solenoid valve, if the water in the tub is not enough to cover the heating element - Motor (55 rpm clockwise, 55 rpm anti-clockwise, 250 rpm pulse) Door closed Check for leaks Water level above the from the tub heating element - Door safety interlock - Drain pump - Motor up to 650 rpm then at maximum spin speed (**) Door closed Water level lower than anti-boiling level for spinning Drain, calibration of analogue pressure switch and spin Door closed Check the correc
5.3.1 ALARMS 5.4 Displaying the alarms to the user When a problem occurs in the appliance, the LCD display shows a “WARNING”: In stylings TC3 and TC2 with a code (in the three digits, where the time until the end of the cycle is represented). In styling TC1, a message is shown (in the text line). This information ceases to be displayed when the problem is repaired/solved. The buzzer then emits a sound (three short “beeps”every 20” for 5 minutes). This does not occur for alarm EH0.
5.5 Reading the alarms The last three alarms stored in the FLASH memory of the PCB can be displayed: 5.5.1 TC3 – TC2 styling Enter the diagnostic mode (para. 7.1). Irrespective of the type of PCB and configuration, turn the programme selector knob clockwise to the eleventh position, the last alarm will be displayed. To display previous alarms, touch the sensor closest to the START/PAUSE sensor in sequence (as shown in the figure). To return to the last alarm, touch the START/PAUSE sensor. TC3 TC2 5.
5.7 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. TC3 TC2 1. Enter the diagnostic mode (para. 7.1). 2. Turn the selector clockwise until the eleventh LED lights up. 3. Touch the START/PAUSE and the nearest option sensor simultaneously (as shown in the figure). 4.
6 OPERATING TIME COUNTER Using a specific procedure, the operator can display the total operating time for the appliance, which is counted from the moment it is first switched on. The unit can count up to a maximum of 6,550 hours of operating time. Only the operating time of normal programmes (and not diagnostic cycles) is counted. The actual operating time for the cycle is counted (which does not include pauses, delayed start time, rinse hold time and soaking phases).
7 OPTIONS 7.
7.2 Description of options Rinse hold During the cycle the intermediate rinses and spins are performed. Stops the appliance with water in the tub before the final spin cycle. To drain the water, simply press the START/PAUSE button to run the drain and spin cycles. Pre-wash Adds a pre-wash phase at the start of the cycle with water heating to 30°C (or cold, if selected). In COTTON and SYNTHETICS cycles, performs a short spin before passing on to the washing phase.
Easy-iron In COTTON programmes: - adds three rinse cycles - eliminates intermediate spin cycles - performs a pulse spin phase before the final spin - adds an “untangling” phase after the spin cycle In SYNTHETIC FABRICS programmes: - it reduces the heating temperature in 50/60°C cycles to 40°C - increases the wash time - prolongs the cooling phase at the end of the wash phase - adds one rinse cycle - adds an “untangling” phase after the pulse spin cycle Hot & Cold Water (only for TC3 styling with pre-set co
