Service Diagnostics and Procedures

Control Board Diagnosis
(Some measurements require power and others require the unit not to be powered.)

Water Heater

The unit uses a 120-volt, 1200 watt heater to heat
the water during the wash cycle. To check the
heater, unplug the gray wire on P12 and using an
ohmmeter, check for 12 ohms between the gray
Ω
wire and Neutral. If 0 ohms are read, check the
Ω
wiring to the heater. If the wiring is correct, replace
the heater. The heater can also be tested in the
Diagnostic mode (see page 12).
