Common Questions
17 totalHow do I prevent drainage issues?
Regularly check and clean the drain pump filter to prevent blockages and ensure the drainage system is not blocked. This maintenance task helps avoid drainage problems during operation.
How do I access the diagnostic cycle on my Electrolux washing machine?
Press and hold down the START/PAUSE button along with a neighboring OPTION button, switch off, then turn on by rotating the program selector clockwise until the LEDs start flashing (at least 2 seconds). The first position will test button functionality while moving further positions activate component diagnostics.
What does the E11 error code indicate and how should I proceed?
E11 signifies difficulty in filling water due to several issues like low water pressure, improper fitting of drain or fill pipes, faulty solenoid valve, etc. The cycle pauses with door locked; check for these issues.
Why does my washing machine show error E43 and how can I fix it?
E43 denotes problems related to the safety interlock triac circuit. This often requires professional service intervention as it involves potential electrical issues that could be dangerous without proper knowledge (Refer diagnostic table for exact causes).
What should I do if water leaks during the wash cycle?
Error E35 suggests possible faults including leaking circuits, incorrect valve positioning or blockages affecting drainage mechanism. A safety drain operation continues attempting to correct this issue for a period.
How can I reset the configuration errors in my washing machine?
Configuration alarms such as E93 indicate incorrect setup data which needs specific corrections that might require professional intervention since these cannot be self-corrected (Refer to troubleshooting guidelines provided for steps).

INTRODUCTION
The purpose of this Service Manual is to provide a simple and clear description of the procedure to be followed by service engineers when confronted by problems identified by the various alarm codes generated by appliances with the EWM1100 electronic control system.
Depending on the configuration of the appliance, the alarm codes may be displayed partially or completely to the user (the alarm codes are generally displayed partially). The diagnostic system can be used by service engineers for the following purposes:
♦ To read the alarms
♦ To cancel alarm conditions stored in memory
♦ To test the operation of the appliance

In the first position, the cycle tests the operation of the buttons and the relative LEDs. If the selector is turned clockwise, the cycle performs the diagnostics for the various components and reads the alarm codes.|
#### 4.2 Exiting the diagnostic system
→ To exit the diagnostic system, switch off, switch on and switch off again the appliance.
#### 4.3 PHASES OF THE DIAGNOSTIC CYCLE
Irrespective of the type of PCB and the configuration of the programme selector it is possible, after entering diagnostic mode, to perform diagnostics on the operation of the various components and to read the alarms by turning the programme selector clockwise. All the alarms are enabled during the diagnostic cycle.
|Position of selector
|Position of selector
|Components activated|Conditions of operation|Function tested| |---|---|---|---|---| |1||- All the LEDs light in sequence
- When a button is pressed, the corresponding LED lights (and the buzzer may sound)
|Always enabled|Operation of the user interface| |2||- Door safety interlock
- Washing solenoid valve
|Door locked Water level lower than antioverflow level Maximum time 5 minutes|Water ducted through washing compartment| |3||- Door safety interlock
- Pre-wash solenoid valve
|Door locked Water level lower than antioverflow level Maximum time 5 minutes|Water ducted through pre-wash (bleach) compartment| |4||- Door safety interlock
- Washing and pre-wash solenoid valves
|Door locked Water level lower than antioverflow level Maximum time 5 minutes|Water ducted through conditioner compartment| |6||- Door safety interlock
- Wash solenoid (if the water in the tub is below 1st level)
- Heating element
|Door locked Water level > 1st level Maximum time 10 minutes or up to 90°C (*)|Heating|
|7||- Door safety interlock
- Wash solenoid (if the water in the tub is below 1st level)
- Motor (55 rpm clockwise, 55 rpm anti-clockwise, impulse at 250 rpm)
|Door locked Water level > 1st level|Check for leaks from the tub| |8||- Door safety interlock
- Drain pump
- Motor up to 650 rpm then at maximum spin speed (**)
|Door locked Water level lower then antiboiling level for spinning|Drain and spin| |9||- Only for top-loaders with drum positioning system:
- Door safety interlock
- Motor (25 rpm)
- Drain pump
|Door locked Water level lower then antiboiling level Maximum time 2 minutes|Test for positioning of drum|
(*) In most cases, this time is sufficient to check the heating. However, the time can be increased by repeating the phase without draining the water: pass for a moment to a different phase of the diagnostic cycle and then back to the heating control phase (if the temperature is higher than 80°C, heating does not take place).
(**) The check at the maximum speed occurs without control of the FUCS and no clothes have to be
inserted inside the appliance.
5 ALARMS
#### 5.1 Displaying the alarms to the user
The alarms displayed to the user are listed below:
Door open Drain difficulty (dirty filter) Water fill difficulty (closet tap)
AEG Version
The alarms are represented through the flashing of the yellow LED, which is above the START-PAUSE button, and can be solved directly by the end user.
####### Other versions
The alarms are represented through the flashing of the red LED, which is inside the START-PAUSE button, and can be solved directly by the user.
|| |---|
|| |---|
The alarms listed below, instead:
Water leakage (Aqua Control System) Low electric voltage Irregular frequency of the electric network
are displayed to the user, but for their solution it is necessary the intervention of the Service. The alarms are enabled during the execution of the washing programme, with the exception of alarms associated with 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 condition that:
Certain alarm conditions require that a drain phase be performed before the door can be opened for safety reasons:
#### 5.2 Reading the alarm codes
It is possible to display the last three memorised alarms in the FLASH memory of the electronic board:
|| |---|
AEG Version: The alarm is displayed by a repeated flashing sequence of the START / PAUSE button with yellow and red light (0,5 seconds on, 0,5 seconds off with a 2,5 second pause between the sequences).
|| |---|
|| |---|
|| |---| ||
These two LEDs are featured in all models.
Other versions: The alarm is displayed by a repeated flashing sequence of the START / PAUSE button with red and green light (0,5 seconds on, 0,5 seconds off with a 2,5 second pause between the sequences).
These two LEDs are featured in all models.

#### 5.3 Rapid reading of alarm codes
The last three alarm codes can be displayed even if the programme selector is not in the tenth position (diagnostics) or if the appliance is in normal operating mode (e.g. during the execution of the washing programme):
→ Press and hold down START/PAUSE and the nearest option button (as to enter the DIAGNOSTICS), for at least two seconds: the LEDs initially switch off, and then display the flashing sequence indicating the last alarm.
→ To display the previous alarms press the left button of the START/PAUSE button sequentially.
→ To return to the last alarm, press the START/PAUSE button.
→ The alarm sequence continues as long as the two buttons are held down.
→ The alarm reading system is as described in paragraph 5.2.1.
→ While the alarms are displayed, the appliance continues to perform the cycle or, if in the programme selection phase, maintains the previously-selected options in memory.
#### 5.4 Cancelling the last alarm

#### 5.6 Notes concerning certain alarm codes
Configuration alarms E93: If these alarms are generated (when the appliance is switched on), operation of the appliance is blocked and all the LEDs light The diagnostic procedure cannot be accessed; the only option is to switch the appliance OFF (by turning the selector to positio
Configuration alarm E94: For this alarm code, only the family for alarm “9” is displayed; the diagnostic procedure cann display” function cannot be used.
Alarms EH1-EH2-EH3: In the event of problems with the mains power supply, the appliance remains in alarm mode until the mains frequency or voltage restored to the correct value or the appliance is switched off (by turning the programme selector to “0”). The family of alarm procedure cannot be accessed, and the “rapid alarm display” function cannot be used. The complete alarm code can be read only w situation has ceased.
Alarms E51- E52: During the diagnostic test, all the alarms are displayed. Normally, when the programme selector is turned from one test phase the appliance exits the alarm condition and performs the phase selected. This does not take place in the case of alarms E51 (po circuited) and E52 (no signal from the tachometric generator on the motor): in these cases, the only option to exit the alarm c OFF by turning the selector to position “0” (reset).
