Theory of Operation
Pressure Switch
The pressure switch is located in the top, right-front corner of the washer. This switch senses the water
level in the drum. The control signal from the pressure switch is sent to the Module Board and is used to
determine the amount of water introduced into the drum during the wash cycle.
