Pressure Sensor
The pressure sensors purpose is to sense the
level of water in the tub when a cycle is being run,
or if the washer is sitting idle.
The pressure sensor cannot be replaced by itself
if it malfunctions or is damaged. The complete
control board will need to be replaced, as the
sensor is mounted directly to it.
The view
shown is how
it's mounted
with the
backsplash
opened laying
on its face.
The pressure sensor can be tested by either
using Test 10 in the Service Mode, or by checking
the output DC voltage of the pressure sensor at
the control board.
To measure the output DC voltage, connect the
meter probes between pin 3 and pin 4.
Depending on how much water is in the basket
will determine what output DC voltage will be
read according to the chart.

Accidentally shorting between pin 2 and pin 3 will
cause the board to shut down, but it will not be
damaged.
