COMPONENT TESTING
Electrical Shock Hazard
Disconnect power before accessing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
B
efore 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
throughout 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.

C
heck all connections before replacing
components, looking for broken or loose
wires, failed terminals, or wires not pressed
into connectors far enough.
Resistance checks must be made with pow-
e
r cord unplugged from outlet, and with wir-
i
ng harness or connectors disconnected.
Unless stated otherwise, make all resis-
t
ance checks by disconnecting the compo-
n
ent connector at the Central Control Unit
(CCU).

Refer to page 4-6 for the procedure for ac-
cessing the inlet valve.
T
o check the inlet valve solenoids at the
component terminals, perform the following
steps.
1.
Unplug washer or disconnect power.
2. Disconnect the solenoid connectors from
the inlet valve terminals.
3.
Set the ohmmeter to the R X 100 scale.
4. Touch the ohmmeter test leads to the
cold and hot water connector terminals.
The meter should indicate between 750
and 850 Ω.
INLET VALVE SOLENOIDS

To check the inlet valve solenoids at the CCU,
perform the following steps.
1.
Unplug washer or disconnect power.
2. Disconnect the inlet valve solenoid con-
nector VCH7 (see page 4-5) from the
CCU.
3.
Set the ohmmeter to the R X 100 scale.
4. Touch the ohmmeter test leads to the fol-
lowing connector pins. The meter should
indicate between 750 and 850 Ω.
