motor control board - Inverter, drain pump, circulation pump - where featured, heating element, door safety interlock,
drum light).
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 washing water via the NTC probe inserted in the heating element.
-
It controls the voltage and frequency of the electricity supply, making sure they are close to nominal values.
-
