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 Ω ohms between the gray
wire and Neutral. If 0 Ω ohms are read, check the
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).
