Motor Start Circuit (Wash and Rinse Cycle)
t. Check the voltage as shown in Figure 33 Position "C,"
NOTE:
Momentary voltage wilt be noted at the instant voltageis appfiad to motor run windin_
, tf novoltage is noted at Position "C" at the instant voltage is applied to motor run winding and a slight humming
noise is heard from the motor; turn the dishwasher off, and remove Blue-Yellow lead wire from terminal "S"
on the start relay..Move the lead on the voltmeter from the white wire to the blue-yellow lead that you removed
from relay. Make a continuity check of this circuit. An open circuit indicates a defective timer or an open wire
in this circuit. If this circuit is "good," the relay is defective.
If voltage is continuous at Position "C" for 2 to 3 seconds, then turn the dishwasher off and remove the
blue-yellow lead from the start relayoCheck continuity between terminal "S" and "L" on the relay, A reading
indicates stuck contact and the relay must be replaced. When this condition is encountered, the motor wi, run
for 8 to 10 secondsbefore the overload protector opens the motor circuit.
4. If voltage is present at Position "C," and the motor hums but will not start, the start winding is open and the
motor must be replaced_
Motor 5tart Circuit (Drain Cycle)
To check the drain start circuit, advance the timer to the drain cycle and repeat the procedure described for the
wash start circuit with exceptions noted below:
