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 (P3.0) electronic control system

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 With universal motor

“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 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

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 (Code 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 in 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. It is strictly forbidden to 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.

3.2.2.1 Programme configuration

The table below lists the parameters that can be used to define the washing programmes.

3.2.2.2 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 center 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.

Technical Support - MDM 9/84 599 78 10-24 Rev.01

Page 10

Every time you touch a sensor, you need to lift your finger up by a centimeter and half a second needs to elapse

L13

before touching it again, otherwise the electronic system does not recognize 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.

3.2.2.3 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. Press the ON/OFF button to cancel the chosen programme. To switch the appliance off, hold down the button for 1 second, the buzzer will at the same time sound a tone (if enabled), all the LEDs 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.

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.

The recommended intermediate spin speeds are: 800 rpm for the following programmes: Lingerie, Duvet, Shirts, Sport, 14 min., Silk, etc…

1,000 rpm for the Easy-Iron option 1,200 rpm for synthetic fabrics, delicates, wool

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 1,000 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) above, 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): Super Quick

Easy Iron Intensive Pre-wash Daily Half-load Soak

The two LEDs (at the bottom) are combined with: Rinse Only – performs the last rinse cycle for the selected programme. If “Extra Rinse” is set, two or more rinse

cycles are added (depending on the configuration)

Spin/Drain – performs the spin cycle for the selected programme, if the selected option is “No Spin” it only drains

off the water.

 Sensor no.5: START/PAUSE

L24

L26

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.

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 and it is related to LED (26). 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 oneminute 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”.

 Padlock When the related LED (L25) 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 (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.

The following information also appears on the display:  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. When the time is less than an hour, the initial zeros are not displayed.

 End of cycle End of the programme is indicated by a permanently lit zero

(when the door can be opened).

 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.

 Alarm code Indicates an anomaly during operation of the machine. Simultaneously to the displaying of the code on the LCD display, the LED above the START/PAUSE sensor flashes

 Calculate amount of washing Only for appliances with PROPORTIONAL programmes

After starting the washing programme the dot starts to flash. At this point the washing machine calculates the amount of washing inside the drum. When this phase ends the dot lights up fixed and the three digits display the programme time.

3.2.2.5 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 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

L28

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.

 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).

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 regularly (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.

6.1 Displaying user 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:

 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.

10.3.1 General characteristics

1 Wheel 2 Rotor 3 Stator

The pump, which drains the water at the end of the various washing cycle phases, is centrifugal and is activated by a synchronous motor. The rotor consists of a permanent magnet and the direction of rotation can be either clockwise or anticlockwise. It can turn by approximately a quarter of a revolution without turning the wheel. Consequently, if a foreign body is stuck in the wheel, the rotor can perform small movements clockwise and anticlockwise until the foreign body is released. The flow rate of these pumps is approximately 18÷20 l/min, and the maximum head is 90 cm. above ground level. Fitted with overload cut-out.

Important Synchronous pumps, when powered on empty (disconnected from the water circuit), may not start in some cases because their very construction makes them need an antagonist torque on the wheel to allow the rotor to move in one of the two directions. The pumps should therefore only be tested once fitted to the appliance, after a little water has been filled.

The drain pump is powered by the main circuit board through a triac, as follows:

 For a pre-determined period (and an alarm might be displayed - see table of alarms).  Until the electronic pressure switch closes on empty, after which the pump is actuated for a brief period or

passes to the subsequent phase.

The electronic pressure switch is an analogue device that controls the water level in the tub, used in models with electronic control system, and it is directly connected to the main PCB.

1. small pipe

2. core

3. oscillating coil

The pressure switch is connected via a pipe to the pressure chamber. When water is introduced into the tub, this creates a pressure inside the hydraulic circuit that causes the membrane to change position. This in turn modifies the position of the core inside the coil, thus changing the inductance and the frequency of the oscillating circuit. The PCB recognizes how much water has been introduced into the tub according to the frequency.

Operating frequency variation according to the quantity of water in the tub.

The instantaneous door interlock allows the door to be opened as soon as the drum stops, if the conditions described hereafter are met.

 When the programme starts (start/pause button) the main circuit board sends a voltage pulse, lasting 20 msec.,

to the solenoid valve (2) (at least 6 seconds should have passed since turning it on), which moves the cam (4) to a locking position; the blocking pin (5) is pushed, locking the cursor (8), which moves behind the ratchet (2) to prevent it from turning, locking the latch inside the lock (see subsequent figures); simultaneously the main switch contacts are shut (6).

Page 39

 When the programme ends or the Start/Pause button is pressed, the circuit board sends two additional

20 msec pulses (200 msec apart):

 The first pulse moves the cam (4) by another position, without releasing the pin (5).  The second pulse (which is only sent if everything is in working order) moves the cam (4) to another position,

which causes the pin (5) to return to its position and therefore release the interlock; the contacts of the main switch are simultaneously opened.

Solenoid protection A PTC is connected in series to the solenoid to limit the current (and therefore any overheating) in the following

cases: main circuit board Triac short circuit many consecutive pressings of the start/pause button (more than 5 times)

Appliance door/door open conditions Before pulses are sent to release the door, the PCB checks for the following conditions: The drum must be stationary.

The water level must not be higher than the lower edge of the door. The temperature of the water must not be higher than 40º C.

10.7.2.1 Mechanical operation

1 Hake 2 Ratchet

When the appliance door closes, the latch (1) fits inside the ratchet (2).

Which, turning on itself, hooks onto and locks the ratchet in place.

If the appliance is switched off or paused and the appliance handle is pulled, the latch is released from the ratchet (2), effortlessly, whereas if the START/PAUSE button has been pressed, the cursor (8) - being locked - does not allow the ratchet to turn (2) so the fastening latch is locked for the entire wash cycle.

10.7.3 Manual opening of the appliance door:

Door safety interlock

Previous instantaneous door safety interlocks released the lid automatically, in the following cases:

 Power failure  The appliance being turned off at the ON/OFF button (before the wash cycle ended)

Whereas, in case of malfunction:

 of the solenoid valve  main PCB faulty

the appliance had to be turned off to release the lid (by unplugging it from the mains supply). Because inside they had a PTC bi-metal which allowed the lid to be opened after cooling, between 55 seconds and 4 minutes.

The new device (since it does not have a PTC) in the case of the above malfunctions is fitted with a manual opening system, which allows the door to be opened following the instructions below:

Before proceeding with the manual opening of the appliance door, check: 1 That the drum is stationary.

2 If the water is above the lower level of the appliance door, drain off the water; if possible set a drainage

programme (see point 4) or unplug the appliance from the mains socket, disconnect the main drain pipe, lay it

on the ground and drain off the water (see point 5). 3 If the water is not above the lower level of the door, then it can be opened manually. 4 Unplug the appliance from the socket. 5 Activate the manual opening system.

To access the manual opening, proceed as follows: Remove the worktop (see para. 50). Press the plastic arch placed above the door safety device twice (shown by the dotted arrow) in order to trigger the

cam which leverages and releases the cursor to allow the latch to be removed from the ratchet.

Voltage on motor

10.8.1 General characteristics

Collector motors are fitted on appliances with a spin speed of between 600 and 1,600 rpm.

1. Stator

2. Terminal board

3. Collector

4. Tachometric generator magnet

5. Tachometric generator coil

6. Brush

10.8.2 Operating principle

The stator winding is connected in series to the rotor winding (serial excitation). Every section of the rotor winding is connected to a pair of collector blades (also referred to as a switching device). The electrical contact between the collector and the fixed circuit is made by two static brushes on the collector blades. The speed of rotation of the motor is proportional to the supply voltage, supplied by an electronic control. This type of motor is also referred to as “universal” because it can be powered by either alternating or direct current.

10.8.2.1 Motor speed control

 This is achieved by an electronic control, by varying the voltage (V) applied to the motor.  The method adopted is the “phase partialization” command of the TRIAC. The TRIAC is an electronic

bidirectional switch. Closing of the circuit between A1-A2 (anodes) occurs when there are appropriate starting pulses on gate (G).

Technical Support - MDM 41/84 599 78 10-24 Rev.01

Page 42

10.8.2.2 Direction of rotation of the motor The direction of rotation of the motor depends on how the windings of the stator and rotor are connected to one

another. This connection is made by the circuit board relay contacts.

Clockwise rotation Anti-clockwise rotation

EC Electronic control P Overheating cut-out (motor) S Stator M Rotor T Tachometric generator TY Triac K3.4 Inversion relay

10.8.2.3 Tachometric generator

The speed of the collector motor, like all motors with serial excitation, depends on the load; so the speed decreases as the load increases. This makes it necessary for the power supply voltage to the motor, and therefore its speed, to be constantly controlled by an electronic speed control. A tachometric generator, consisting of a magnet secured to the shaft and a coil, generates a voltage depending on the speed of the rotor, which is sent to the electronic control. All the electronic controls have a protection system, which is more or less sophisticated, to avoid the operation of the motor in the event of a failure in the tachometric generator.

10.8.3 Power supply to motor

The PCB powers the motor via a TRIAC switch; the direction of rotation is reversed by switching the contacts on the two relays (K1-K2), which modify the connection between the rotor and the stator. In certain models, a third relay (K3) is used to power the stator (full or half field) according to the spin speed. The motor speed is controlled by the signal from the tachometric generator. During the spin phases, the micro-processor performs the anti-foam and the anti-balancing check procedure.

10.9 Anti-foam control system

The anti-foam control procedure is performed using the electronic pressure switch.  Spin with little foam: if the pressure switch senses a “full” level, the spin phase is interrupted, the drain pump

continues to operate and, when the pressure switch senses “empty”, the spin phase is resumed.

 Spin with excess foam in the tub (critical situation): the control system detects whether the electronic

pressure switch switches 5 times to full (five spin interruptions). If this occurs, the spin phase is skipped, and a one-minute drain cycle is performed with the motor stationary and, in the case of a washing phase, a supplementary rinse is added.

10.10 Solenoid valves

1. Main electronic circuit board

2. Door safety interlock

5. Pre-wash solenoid valve

6. Wash solenoid valve

10.10.1 General characteristics

This component introduces water into the detergent dispenser and is controlled electrically by the main circuit board via Triac. The level of water in the tub is controlled by the analogue pressure switch.

1. Water inlet

2. Solenoid valve body

3. Filter or needle trap

4. Flow reducer

5. Coil

6. Spring

7. Moving core

8. Rubber

9. Membrane

10. Water outlet

10.10.2 Operating principle

When idle, the core, pushed by a spring, keeps the central hole of the membrane closed and so the latter hermetically seals access to the water inlet duct. When the coil is powered, the core is attracted, releasing the central hole of the membrane. Consequently the valve opens.

10.10.3 Mechanical jamming of the solenoid valve

The solenoid valve may jam open without being actuated (which will cause flooding if the pressure switch controlling the water level does not trip). If this occurs, the electronic control system (which continuously monitors the flow sensor) will lock the door, start the drain pump and display an ALARM simultaneously.

10.10.4 Low water pressure

If the flow sensor does not generate a signal during the water fill phases, even though power is being supplied to the solenoid valve, the cause of this condition may be a closed water tap or clogged filter on the solenoid valve (with ensuing low water pressure). If this occurs, only a WARNING will be displayed and the cycle will continue for five minutes, after which time an ALARM will be signaled.
