PRESSURE SWITCH
The pressure switch is located in the top right
rear corner of the washer. 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 automatic 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 pres-
sure switch, the CCU will turn on the drain
pump and attempt to stop filling.
