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-
per-volt DC, or greater.
• 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
Refer to page 4-13 for the procedure for servic-
ing the pressure switch.
1. Unplug washer or disconnect power.
2. Disconnect the hose and wire connector
from the pressure switch.
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.
