Electronic Control; Programming/Updating The Main Circuit Board - Electrolux EWX13611 Service Manual

Electronic control

10.7
The electronic control is made up of:
1. Main electronic circuit board.
2. Control/display circuit board.
3. INVERTER motor control board where featured
(not shown in the figure).
The control/display PCB contains: the display (where featured), to display the programme information; the touch
sensors, to adjust the temperature, the spin speed and possibly select an option, the START/PAUSE button,
the ON/OFF button and lastly the LEDs which (when lit) indicate the selections made.
The commands acquired by the display board are sent to the main circuit board, which powers all the electrical
components (cold water solenoid valve, drain pump, heating element and door safety device, etc.) and concurrently:
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 (where featured).
To guarantee proper performance of the washing cycle.

10.7.1 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:
