20 TECHNICAL CHARACTERISTICS
20.1 Electronic control
The electronic control is made up of:
1. Main circuit board
2. Control/display circuit board
The control/display circuit board acquires the commands for cycle set-up. This board includes:
buttons, LEDs, display (where featured), programme selector and temperature control (where featured).
The commands acquired by the display board are sent to the main circuit board, which powers all the electrical
components (solenoid valve, wash motor, drain pump, heating element and door safety device).
•
It controls the temperature of the washing water via the NTC probe inserted in the heating element.
•
It controls the motor rotation speed using the signal from the tachometric generator.
•
It controls the level of water via the analogue pressure switch.
20.1.1 Programming/UPDATING THE MAIN CIRCUIT BOARD
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:
Technical Support - DMM
1
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).
