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).
