1 INTRODUCTION
1.1 Purpose of this manual
The purpose of this manual is to explain, simply and schematically, the steps any Technician must take
when faced with the problems indicated by the various alarm codes on appliances with electronic control in
the EWX11831 series, THE INSPIRATION RANGE TC4-TC3 version
Depending on the appliance configuration, the alarms may be entirely or partially displayed to the user:
the latter solution is usually adopted.
The diagnostics system is used by Service Technicians to:
Read alarms
Delete the alarm stored
Test the appliance operation
1.2 Cautions
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 (Cod. 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 on 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. NEVER
remove/switch the NTC sensors between heating elements.
Always empty the appliance of all the water before laying it
on its side.
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.
The resistance values of the components shown in this S.M. are purely indicative
(relating to a sample appliance with new components).
For the actual value of the component, please refer:
to S.B. 599706597 for motors, while for the other components, please consult S.M.
599728903 “Component Characteristics”.
Do not place any kind of container under the appliance to catch any drips of
water.

1.3 How to proceed
1. Identify the type of control in question (page 7) and access the diagnostic cycle. (see page 8)
2. Read the alarm stored (page 13) and consult the instructions regarding the “alarm codes”, page 14÷18.
3. Delete the alarms stored. (page 13)
4. If you are unable to access the diagnostic mode, consult the chapter entitled “The diagnostics system
cannot be accessed”. (page 19)
5. Should the main electronic circuit board need to be replaced, make sure there are no burns.
(see page 69)
6. After all interventions, check the appliance is operating correctly using the diagnostic cycle. (page 9)
7. Delete any alarm that may have been stored during the diagnostics operations. (page 13)

2 APPLIANCE CONTROL PANELS
These are the stylings available at the time of printing of this Service Manual. Others may be developed in
future.
3 PROGRAMMING/UPDATING THE MAIN BOARD
Any programming / updating / diagnostics operation carried out with the
board inserted in the machine and the mains plug disconnected from the
socket.
If one of these operations is accidentally carried out when plugged in to the
socket, on completing the operation, the appliance will remain turned off
when restarting; disconnect the plug from the socket and wait at least
40 minutes before starting up the appliance (any operation will only create
further delay).
In the Service Notes the main circuit board (587) is identified with two spare parts codes:
Code 973 914… identifies the pre-programmed board.
Code 132… identifies the unprogrammed board.
The circuit board can be programmed/updated using the Sidekick application.
For further information, please refer to the instructions provided/illustrated in the course entitled << Guide
to Sidekick >> at the address (http://electrolux.edvantage.net) on the Electrolux Learning Gateway portal.
To update/program the main board, insert the Sidekick connector in
the position shown by the red arrow:

(*) 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 A.G.S. and no garments must be inside the appliance.

4.4 ALARMS
4.4.1 Displaying the alarms to the user
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.
This does not occur for EH0 alarm.

For its solution, the intervention of a Service engineer is required
The other alarms are displayed by a code
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
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.

4.4.2 Reading the alarms
The last three alarms stored in the FLASH memory of the PCB can be displayed:
enter the diagnostic mode (para. 4.1)
Irrespective of the type of PCB and configuration, turn the programme selector knob
clockwise to the eleventh position and the last alarm is displayed.
to display previous alarms, touch the sensor closest to the START/PAUSE sensor in
sequence (as shown in the figure)
To return to the last alarm, touch the START/PAUSE sensor.
4.4.3 Rapid reading of alarms
The last alarm can be displayed even if the programme selector is not in the eleventh position (diagnostics)
or if the appliance is in normal operating mode (e.g. during the execution of the washing programme):
→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.
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.
4.4.4 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
N.B. With this operation all the alarms stored are deleted.

4.6 Notes on the behaviour of certain alarms
Configuration alarm E93: when this alarm rings (when turned on) the machine blocks and the alarm code appears on the display, provided the relevant
configuration part is intact.
It is not possible to access diagnostics mode and the only available option is to turn the appliance off.
Configuration alarm E94: and the code can be viewed from the display.
The diagnostics mode cannot be accessed and the “quick alarm viewing” mode cannot be used.
Alarms EH1-EH2-EH3: in the event of problems with the supply voltage, the appliance remains in alarm status until the mains frequency or voltage returns to
acceptable values or the appliance is switched off (ON/OFF button). Only the “H” alarm family is displayed if the problem occurs while the appliance is
working normally, the code is shown simultaneously on the display.
The diagnostics mode cannot be accessed and the “quick alarm viewing” mode cannot be used: the alarm can only be read in full when the situation has
normalised.

Run the diagnostic cycle and fill all the trays with water (phases 2,3,4,5,6)
Are all the trays filling with water?
6 TROUBLESHOOTING BASED ON ALARM CODES
E11
E11: Water fill difficulty during washing
E11
Maximum water fill time for every level of the pressure switch
(the time is reset every time the level is achieved)
Checks to perform:
Repair the drain circuit and repeat the
diagnostic cycle to check for any further alarms.
Repair the water circuit of the pressure switch
and repeat the diagnostic cycle to check for
any further alarms.
Replace the main circuit board and repeat the diagnostic cycle to check for anyfurther alarms.
Is the drain pipe positioned
correctly and not causing the siphon
effect? (fig.1)
Is the pressure switch's water circuit
efficient (leaking/clogged)? (fig. 2)
Check whether the tap is open, if the water
pressure is too low and make sure the tubes are
connected and not kinked
Is one or are all the solenoid valves not
working?
Replace the solenoid valve and repeat the
diagnostic cycle to check for any further alarms.
Is the resistance measurement of the solenoid
valve approximately 3.5÷4.5K? (Measure it
directly on the solenoid valve without wiring)
-(see fig. 3)-
Replace/repair the wiring and repeat the
diagnostic cycle to check for any further alarms.
Reconnect the connector and measure
approximately 3.5÷4.5Kon the solenoid valve
wiring connector on the circuit board side (fig.4):
Between J18-1 and J18-3 wash
Between J18-4 and J18-6 pre-wash
Between J20-1 and J20-3 third solenoid valve
Between J20-4 and J20-6 hot water
Is the solenoid valve wiring ok?
Replace the main circuit board and repeat the
diagnostic cycle to check for any further alarms.
Repair the water circuit and repeat the
diagnostic cycle to check for any further alarms.
