10.6  Electronic control 

 
The electronic control is made up of: 
 
 

1.  Main electronic circuit board 
2.  Control/display circuit board 

 
 

The control/display PCB contains: the selector used to select the washing programme, the LCD display to show 
information on the programme, but buttons used to adjust the temperature, the spin speed and optionally to 
select an option, the START/PAUSE button and finally the ON/OFF button. 
The commands acquired by the display board (by turning the selector, selecting an option, etc...) are sent to the 
main circuit board, which powers all the electrical components (cold water solenoid valve, drain pump, heating 
element, door safety interlock, etc.) and: 

 

It controls the level of water via the analogue pressure switch. 
It controls the state of the door. 
It controls the speed of the motor. 
It controls the temperature of the wash water via the NTC probe inserted in the heating element. 
It controls the voltage and frequency of the power supply and ensures they are close to the rated ones. 
It controls the flow of water through the solenoid valve via the flowmeter. 
 
At the same time it controls their operation to guarantee proper performance of the washing cycle. 
 

10.6.1  Programming/Updating the main circuit board  

 

 

 

Any programming/updating/diagnostics operation carried out with the board 

installed on the appliance 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

 

<< 

Sidekick Guide

 

>> at the link (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:
