Reading The Alarm Codes; Displaying The Alarm; Examples Of Alarm Displays - Electrolux washing machine Service Manual

10.2 Reading the alarm codes

In order to read the last alarm code memorized in the EEPROM on the PCB:
•
Enter diagnostics mode
•
Irrespective of the type of PCB and configuration, turn the programme
selector clockwise to the tenth position.

10.2.1 Displaying the alarm

The alarm is displayed by a repeated flashing sequence of the two LEDs (0.4
seconds lit, 0.4 seconds off, with an interval of 2.5 seconds between
sequences).
The buzzer (if featured) will sound "bips" in synchronization with the flashing of
the LEDs.
• END OF CYCLE LED → 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 featured on all models (though they are configured
differently), and flash simultaneously.
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 a series of LEDs.

10.2.2 Examples of alarm displays

Example: Alarm E43 will display the following:
•
On the display, if featured, E43
•
The sequence of four flashes of the End-of-cycle LED indicates the first number E
•
The sequence of three flashes of the Start/Pause LED indicates the second number E4
