accessing the pressure switch.
To check the pressure switch at the
component terminals, perform the following
steps.
Unplug washer or disconnect power.
Disconnect the wire connector and hose
from the pressure switch.
Set the ohmmeter to the R X 1 scale.
Touch ohm meter leads to terminals 21 &
22, continuity will be read without water in
the washer. As water enters the washer
the next switch to close is Suds Level

11 & 14. The next switch to close is the
Wash Level read at terminals 21 & 24.
Finally if water were to rise high enough,
