SECTION 4. ELECTRICAL COMPONENTS & TESTING
ELECTRICAL TESTS
Warning - Always shut off
electrical power to the
washer before beginning
any service repair
procedures.
Grounded Components
When performing service diagnostics,
replacements and repairs, always check to
determine whether all ground wires
linking panel and components are
reattached if removed.
Water Valve Test
The water valve test is similar to the test
outlined in the 16008373 manual, except,
to check the ohm resistance of thermistor,
pull the P3 wire harness connector off the
machine control and locate the P3(6) and
P3(7) leads in the connector on the
machine control board. Note the
thermistor has been relocated on the
valve to the outlet of the valve. (See
Figure 4-1)
The thermistor is on NTC and will drop in
resistance when the temperature
increases.

following procedure.
