Pressure Switch

Pressure Switch

The pressure switch is located in the top right rear corner of the washer. (Fig. 3-7)This switch senses water level in the wash tub. The control signal from the pressure switch is sent to the Central Control Unit and is used to determine the amount of water introduced into the wash tub during the wash cycle.

The pressure switch also senses the suds level in the wash tub. If excessive sudsing occurs, the washer starts an auto- matic suds routine. The display will show the word “Sud”. The automatic suds routine adds additional rinse and drain operations until the suds level is reduced.

If an overfill condition is detected by the pressure switch, the CCU will turn on the drain pump and attempt to stop filling.
