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.

Circulation Motor
The 200 Series Dishwasher uses a single
speed, capacitor assist wash motor. Voltage
between P5-1 and P5-2 should be 120 VAC
when the motor is activated. If voltage is not
present, verify wiring. If voltage is present and
the motor is not running, check the capacitor
and motor windings for proper readings.
Note: Testing the circulation motor can be
achieved in the diagnostic mode.
Fill Valve
The dishwasher uses a ll valve to ll the
machine with water. Verify as the valve is
energized 120 VAC is present between P6-3
and P10-1. If voltage is present and no water
enters, check the water supply and shut off
valve to make sure water is being supplied to
the unit. If water is present, unplug the wires
to the ll valve and using an ohmmeter, check
for approximately 1.1k Ω ohms at the coil. If
0 Ω ohms are read, replace the ll valve (see
Fill Valve Disassembly procedure, page 31).
Note: Testing the ll valve can be achieved in
the diagnostic mode.
