COMPONENT TESTING
Before testing any of the components, perform the following checks:
•Control failure can be the result of corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary through- out test procedures.
•All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms-
•Check all connections before replacing com- ponents, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.
•Resistance checks must be made with power cord unplugged from outlet, and with wiring harness or connectors disconnected.
•Unless stated otherwise, make all resis- tance checks by disconnecting the compo- nent connector at the Central Control Unit (CCU).
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
PRESSURE SWITCH
2.Disconnect the hose and wire connector from the pressure switch.

1.Unplug washer or disconnect power.
3.Set the ohmmeter to the R X 1 scale.
4.Touch the ohmmeter test leads to the
pressure switch connector pins shown below. The meter should indicate 0 Ω for each measurement.
