Water Heater - Viking FDB451 Service Manual

To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.
(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 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).
