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 and EWX11831 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 Models with universal motor (EWX13611 board)
"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 Models 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 W ARNINGS
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.
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 to avoid static electricity from damaging the circuit board,
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 in the display board could be at a potential of 240 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. Make sure you wear gloves, because parts of the cabinet are sharp.

The washing programmes and the functions and the various touch sensors vary according to the model, since these are determined by the configuration of the appliance. 3.3.2.1 Programme configuration
The table below lists the parameters that can be used to define the washing programmes. Types of fabric Special programmes Temperature Spin Options (Normal/Possible) Programme phases Cotton/linen, Synthetic fabrics, Delicates, Wool, Hand-wash, Shoes, Jeans, Duvet, Silk. Cotton/linen + pre-wash, Soak, Miniprogramme, Easy-Iron, Conditioner, Rinse, Drain, Spin, Economy. Normal, Minimum, Maximum: the initial temperature is the one proposed for the washing programme. Normal, Minimum, Maximum. Rinse Hold, Pre-wash, Extra rinse, Easy-Iron, Economy (energy label), Normal, Super quick, Reduced spin speed, No spin. 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. 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. S1 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. S2 L13 L9

Sensor no. 3: SPIN SPEED (configurable) The function of the third sensor is dedicated to the spin speed selection, combined with the five LEDs (L14÷L18) above; the related speed is silk-screen printed beside them on the control panel. The initial spin speed is that set for the chosen programme. Touch the sensor to reduce the spin speed, indicated by the LED near the silk-screen printed value on the control panel lighting up at the same time to confirm your selection. Once the lowest speed has been reached, you can, if you wish, select "Rinse hold" and the related LED beside the symbol silk-screen printed on the control panel lights up. The next selection will be the highest speed available for the selected programme. For a quicker selection, hold your finger down on the sensor for longer. The speeds that can be combined with the five LEDs are shown in the following table. S3 L14
L18
The recommended intermediate spin speeds are: 800 rpm for the following programmes: Lingerie, Duvet, Shirts, Sport, Fast wash., Silk, etc... 1,000 rpm for the Easy-Iron option 1,200-14,00 rpm for synthetic fabrics, delicates If you select the "Rinse hold" option when the cycle ends, the related LED flashes to remind the end user to drain the water before opening the appliance door. With the "Easy-Iron" option, the spin speed is reduced to 1000 rpm even if the spin speed selected is higher; if the option is deselected, the speed automatically returns to the chosen value. Sensor no. 4: OPTIONS (configurable) The function of the fourth sensor is dedicated to the choice of option to combine with the programme, combined with five LEDs (L19÷L23), beside which the name of the related option is silk-screen printed on the control panel. Touch the sensor when no option has been enabled (all the LEDs are switched off) to light up the first LED relating to the most important option in the list. Continue your selection to light up the subsequent LED (from the top down) and the previous one is switched off, all the way to the last option at the bottom. The next time you press the sensor all the LEDs will remain switched off. You can only select one option per programme, as no combinations are possible. For a quicker selection, hold your finger down on the sensor for longer. The following options can be combined with the first three LEDs (at the top): Time Save Heavy duty Easy Iron Rinse & Spin Drain & spin L19

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(L26)works as the DELAYED END. Touch it in sequence to choose delayed end options: 3 h-to 20h 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.

Extra Rinse: When the related LED (L27) 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 lock: When the related LED (L28) 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.

ALARMS
7.1 Displaying user alarms
7.1.1 General Description
The alarms are enabled during the execution of the washing programme. With the exception of alarms associated with the configuration and the power supply voltage/frequency, which are also displayed during the programme selection phase. The door can normally be opened (except where specified) when an alarm condition has occurred, on the condition that: The water in the tub is below a certain level. The water temperature is lower than 55 °C. The motor has stopped. Certain alarm conditions require a drain phase to be performed before the door can be opened for safety reasons: Cooling water fill if the temperature is higher than 65 °C. Drain until the analogue pressure switch is on empty, during a max. 3-minute interval.
WM317

7.1.2
Types of Alarms
When a problem arises with the appliance, "WARNING" appears on the LCD screen, represented by a code (three digits, indicating the time required for the cycle to end). At the same time the buzzer gives off three short "beeps" every 20" for a period of 5 minutes. Once the fault has been repaired the buzzer does not give off any "beeps" and the selected programme appears on the LCD screen. Alarms E9x and EHx show the entire code with the red LED + yellow LED, only alarm EHx is not accompanied by the buzzer sounding.
The alarms displayed to the user are listed below and can also be eliminated by the user: E10 Water fill difficulty (tap closed) E20 Drain difficulty (filter dirty) E40 Door open EF0 Excessive detergent (if displayed) E91 No communication between the display board and the main board.Switch ON/OFF E92/E93/E94 Main board not configured correctly. EF0 Water leakage (Aqua Control System) It is displayed to the user, but technical assistance is required to resolve it. EH0 Voltage or frequency outside the normal values It is necessary to wait for power supply voltage and/or frequency to restore nominal conditions. The alarms are enabled during the execution of the washing programme. With the exception of alarms associated with the configuration and the power supply voltage/frequency, which are also displayed during the programme selection phase. The door can normally be opened (except where specified) when an alarm condition has occurred, on the condition that: The water in the tub is below a certain level. The water temperature is lower than 55 °C. The motor has stopped. Certain alarm conditions require a drain phase to be performed before the door can be opened for safety reasons: Cooling water fill if the temperature is higher than 65 °C Drain until the analogue pressure switch is on empty, during a max. 3-minute interval.

7.2.2 Behaviour of the alarms during diagnostic testing All alarms are enabled during diagnostic testing of the components.
7.2.3 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.
WM317
29
7.2.4 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
S1
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.
N.B. With this operation all the alarms stored are deleted.

8 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). The precision of the counter is 30 seconds per programme. Only whole hours of operation are counted (1hr and 59 min. = 1 hr).
8.1 Reading the operating time
The operations listed below must be carried out within 7 seconds.
S1
Switch on the appliance using the ON/OFF button Use sensor S1 to select the position which lights up the fifth LED. Simultaneously press the START/PAUSE button and the nearest option sensor (as shown in the diagram). Keep your fingers over the sensors until the hours of operation appear on the display (at least 5 seconds).
8.2 Display of total operating time
This time is displayed with a sequence of two digits at a time: the first two digits indicate thousands and hundreds, the second two digits indicate tens and units. For example, if the operating time is 6,550 hours, the display will show the following sequence: Phase 1 For two seconds It displays: Hr Phase 2 For two seconds, the following digits are displayed: thousands (6) hundreds (5). Phase 3 For the next two seconds the following digits are displayed: tens (5) units (0).
At the end of phase three (after the tens and units are displayed), the cycle is repeated. To return to normal mode, either: switch off the appliance, press a key.
