10.7 Electronic control
The electronic control consists of:
1. Main circuit board.
2. Control/display circuit board.
3. INVERTER motor control board (not shown in the
figure, positioned at the bottom right of the
appliance seen from the rear).
The control/display PCB contains: the selector dial, to select the washing programme, the LCD display, to
display the programme information; the buttons to adjust the temperature, the spin speed and possibly
select an option, the Start/PAUSE button and lastly the ON/OFF button.
The commands received by the display board (by turning the selector dial, selecting an option, etc…) are
sent to the main circuit board, which powers all the electrical components like: cold and hot water solenoid
valves, motor control board, Inverter, drain pump/valve, heating element, door safety interlock, drum light.
It controls the level of water via the analogue pressure sensor.
It controls the state of the door.
It controls the speed of the motor.
It controls the temperature of the washing 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 measures the flow of water through the solenoid using the flow meter.
It simultaneously controls their functioning to guarantee the correct performance of the washing cycle.
