Electrolux EWM1000 PLATFORM Front Load Washing Machine Fault Diagnostics – error codes display details.

 

ACCESS TO THE DIAGNOSTIC CYCLE

1.Switch off the appliance.
2. Press and hold down the START/PAUSE button and any one of the OPTION buttons simultaneously.  Horizontal version, while for vertical version pushbuttons are 2 and 3.
3. Holding down both buttons, switch the appliance on by turning the program selector one position clockwise.
4. Continue to hold down the START/PAUSE button and the OPTION button horizontal version, while for vertical version pushbuttons are 2 and 3, until the LEDs begin to flash (at least 2 seconds).
5. To exit the diagnostics system switch the appliance off, on and then off again.
IMPORTANT: The position of the START/PAUSE button varies according to the model, and is therefore not always the same.

Rapid reading of alarms
The last alarm can be displayed even if the program selector is not in the tenth position (diagnostics) or if the appliance is in normal operating mode (e.g. while the washing program is in operation)

1. Press START/PAUSE and any one of the option buttons simultaneously for horizontal version, while for vertical version push-buttons are 2 and 3, for at least two seconds: the LEDs first switch off, and then display the flashing sequence corresponding to the alarm condition.
2. The alarm sequence continues as long as the two buttons are held down.
3. While the alarms are displayed, the current cycle being performed continues or, if the appliance is in the program selection phase, the options previously selected remain in memory.

Cancelling the last alarm

1. Access alarm reading mode (tenth selector position)
2. Press and hold down START/PAUSE and any one of the option keys simultaneously for horizontal version, while for vertical version push-button are 2 and 3.
3. Hold the START/PAUSE and OPTION button down until the LEDs begin to flash (about 5 seconds)

Phases of the diagnostics test
After accessing the diagnostics cycle, and irrespective of the type of control board fitted to the appliance (i.e. vertical or horizontal buttons) and the configuration of the selector, turn the program selector clockwise to perform the diagnostics cycle for the various components and to read the alarms.  All the alarms are enabled during the diagnostics cycle.

[In most cases, this time is sufficient to check the heating function. However, the time can be increased by repeating the heating phase without draining the water: pass for a moment to a different phase of the diagnostics cycle and then back to the heating check phase (if the temperature is higher than 80°C, heating does not take place).]

Reading the alarms
Proceed as follows to read the last alarm condition stored in the EEPROM on the control board:
> Access diagnostics mode.
> Irrespective of the type of control board and configuration, turn the programme selector clockwise to the tenth position.
Displaying the alarm
The alarm is displayed by a repeated flashing sequence of the two LEDs (0.4 seconds ON, 0.4 seconds OFF, with a pause of 2.5 seconds between each sequence). The buzzer (if featured) sounds a series of “beeps” in synchronization with the flashing of the LEDs.
> END OF CYCLE indicator  >> indicates the first digit of the alarm code (family)
> START/PAUSE >> indicates the second digit of the alarm code (number within the family).  These two LEDs are present on all models (though configured in different positions) and flash simultaneously.

> The first letter of the alarm code “E” (Error) is not displayed since it is the same for all alarm codes.
> The alarm code families are expressed in hexadecimal form. In other words:
>> A is represented by 10 flashes
>> B is represented by 11 flashes
=> ...
>> F is represented by 15 flashes
> Configuration errors are displayed by the flashing of all the LEDs (user interface not configured).

Examples of alarm display
Example: Alarm E43 (problems with the door safety interlock triac) will be displayed as follows:
> four flashes of the END OF CYCLE LED indicate the first digit E43
> three flashes of the START/PAUSE LED indicate the second digit E43

Status of alarms during the diagnostics cycle
All the alarms are enabled during the components diagnostics test.

Table of alarms codes EWM1000

Notes concerning certain alarm codes Configuration alarms > E93 - E96  If these alarms are generated (when the appliance is switched on), operation of the appliance is blocked and all the LEDs light. The diagnostics procedure cannot be accessed; the only option is to switch the appliance OFF (by turning the selector to position “0”). > E94: For this alarm code, only the family for alarm “9” is displayed; the diagnostics procedure cannot be accessed, and the “rapid alarm display” function cannot be used.
> EB1,EB2, EB3  In the event of problems with the mains power supply, the appliance remains in alarm mode until the mains frequency or voltage are restored to the correct value or the appliance is switched off (by turning the program selector to “0”). The family of alarm “B” is displayed; the diagnostics procedure cannot be accessed, and the “rapid alarm display” function cannot be used. The complete alarm code can be read only when the abnormal situation has ceased.
> E51 - E52  During the diagnostics test, all the alarms are displayed. Normally, when the program selector is turned from one test phase to another, the appliance exits the alarm condition and performs the phase selected. This does not take place in the case of alarms E51 (power triac on motor short-circuited) and E52 (no signal from the tachymetric generator on the motor): in these cases, the only option to exit the alarm condition is to switch the appliance OFF by turning the selector to position “0” (reset).
