Pressure Switch Caution (Not recommended by Factory!)
preset adjustment voids all factory water usage specifications.
The pressure switch sets the water level in the washer. As the water level rises, it compresses the air in
the pressure switch hose. When the washer reaches the desired water level, the compressed air in the
pressure switch hose opens the contacts in the switch, shutting off the water. When at the empty level,
the pressure switch contacts are closed allowing the machine to either spin or fill with water. The 1/4"
screw in the middle of the switch adjusts the water level. Counter clockwise will lower the water level, and
clockwise will increase the water level. Before making any adjustments of the pressure switch, drain the
tub and blow the hose clear of possible water bubbles which can cause erratic pressure switch operation.
