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 Cen-
tral 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.
