INTRODUCTION
1.1
Purpose of this manual
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 EWM2100 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
1.2
Procedure
1. Identify the type of control system (page 6/7) and access the diagnostic cycle
(See page 8).
2. Read the alarm code stored in memory (page 12) and refer to the instructions for the
corresponding alarm code, page 15-19.
3. Cancel the alarm stored in memory (page 14).
4. If access to the diagnostic cycle is not possible, refer to the section “Access to
diagnostic system impossible” (page 20).
5. If the main PCB is replaced, check that there are no burned parts (see page 91).
6. After any repair, always check the operation of the appliance using the diagnostic cycle
(page 9).
7. Cancel any alarms stored in memory during the diagnostic procedure (page 14).

(*) 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:
ª Door open
ª Drain difficulty (dirty filter)
ª 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 its shape depends on the styling) and can be solved
directly by the user;
The alarm listed below:
ª EF0 – Water leakage (Aqua Control System)
for its solution it is necessary the intervention of the Service.
While for the alarm:
ª EH0 – Voltage or frequency out of nominal values
It is necessary to wait that the voltage and/or the frequency of the electric line reset the nominal
conditions.
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:
•
•
•
The level of the water in the tub is below a certain level
Water temperature lower than 55°C
Motor stopped
Certain alarm conditions require that a drain phase 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 time.

5.2
Reading the alarm codes
It is possible to display the last three memorised alarms in the FLASH memory of the electronic board:
• Enter diagnostic mode (par. 4.1)
• Irrespective of the type of PCB and configuration:
turn the programme selector clockwise (version with knob) pushing button P1 (version INPUT)
to the tenth position.
•
The last alarm is displayed.
•
To display the previous alarms, press sequentially the left button of the START/PAUSE button (as
represented in figure).
•
To return to the last alarm, press the START/PAUSE button.
5.2.1
Alarm displaying
AEG Version:
The alarm is displayed by a repeated flashing sequence of the LED placed above
the button START / PAUSE with yellow and red light (0,5 seconds on, 0,5
seconds off with a 2,5 second pause between the sequences).
• LED indicator START / PAUSE with yellow light → indicates the first digit of
the alarm code (family).
• LED indicator START / PAUS with red light → indicates the second digit of
the alarm code (internal number of the family).
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).
• LED indicator START / PAUSE with red light → indicates the first digit of the
alarm code (family)
• LED indicator START / PAUSE with green light → indicates the second digit
of the alarm code (internal number of the family)
These two LEDs are featured in all models.

Notes:
• The first letter of the alarm code “E” (Error) is not displayed, since this letter is common to all alarm
codes.
• The alarm code “families” are shown in hexadecimal; in other words:
→ A is represented by 10 flashes
→ B is represented by 11 flashes
→ ...
→ F is represented by 15 flashes
• Configuration errors are shown by the flashing of all the LEDs (user interface not configured).
5.2.2 Examples of alarm display
Example: Alarm E43 (problems with the door interlock Triac) will display the following:
• the sequence of four flashes of the START / PAUSE button with red light (version AEG LED yellow
•
light), indicates the first number E43;
the sequence of three flashes of the START / PAUSE button with green light (version AEG LED red
light), indicates the second number E43;

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.
→ 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
It is good practice to cancel the last alarm:
•
after reading the alarm code, to check whether the alarm re-occurs during diagnostics;
•
after repairing the appliance, to check whether it re-occurs during testing.
1. Select diagnostic mode.
2. Turn the selector (version with knob) or push button P2 (version INPUT) to the tenth
position (reading of alarm).
3. Press and hold down START/PAUSE and the nearest option button (as represented in
figure).
4. Hold down the buttons till the LEDs stop to flash (at least 5 seconds).
N.B. With this operation all the memorised alarms are deleted.

Notes concerning certain alarm codes
ƒ
Configuration alarms E93: If this alarm is generated (when the appliance is switched on), operation of the appliance is blocked, the LEDs placed above or
inside the START/PAUSE button start to flash displaying the complete codification (family plus alarm), the display shows the alarm code on condition that
the configuration part of the display is ok.
The diagnostic procedure cannot be accessed; the only option is to switch the appliance OFF.
ƒ
Configuration alarm E94: all LEDs placed above or inside the START/PAUSE button start to flash displaying the complete codification (family plus alarm)
and the code is displayed.
It is not possible to enter the diagnostics or to use the mode “rapid displaying of the alarm”.
ƒ
Alarms EH1(Eb1)-EH2(Eb2)-EH3(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 (programme selector on “0”). The family of alarm “b or H” only is
displayed if the problem occurs during the normal operation of the appliance, while the family plus the alarm are displayed if the problem occurs at the
switching on, through the flashing of the LEDs placed above or inside the START/PAUSE button. At the same time the code is represented also in the display.
It is not possible to enter the diagnostics or to use the mode “rapid displaying of the alarm”: the complete alarm can be read only when the abnormal situation has
terminated.
ƒ
Alarms E51- E52: During the diagnostic test, all the alarms are displayed. Normally, when the programme 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 shortcircuited) and E52 (no signal from the tachometric 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) or pushing the ON/OFF button (INPUT styling).

1) Check the connector blocks (wiring)
and check for detached or bent
terminals.
P = motor protector
R = rotor S = stator
T = tachometric generator
2) Check for traces, residue or deposits
of water or detergent on the motor and
identify the source.
3) Check for windings or other parts that
may be grounded or poorly insulated.
Use a tester with a minimum scale of
40 MΩ: between each terminal and the
casing, this should read ∞ (fig. 10).
4) Check each winding against the values
shown in the table below (fig. 11).
