Pressure Switch
The pressure switch is a water valve safety device.
It is located under the tub at the right, front corner.
A clear plastic tube, (the pressure switch hose), runs
from the fl oat switch, around the fi ll funnel, and to
the sump.
As the dishwasher basin fi lls with water, the air
pressure in the pressure switch hose increases.
Normally, the electronic control regulates the
amount of time the water fi ll valve remains open. If
the water fi ll valve remains energized, the overfi lling
of the basin increases the air pressure in the
pressure switch hose, causing the pressure switch to
open the circuit to the electronic control and closing
the circuit to the drain pump. The drain pump then
empties the water in the sump.
7. Label and disconnect the three wires from the
pressure switch. Remove the pressure switch.
6. Turn the fl oat switch clockwise to align the
mounting tab vertically with the mounting
hole and remove the pressure switch from the
dishwasher frame.
