.
Restart. the dishwasher. Voltage at Position "A" indicates voltage to motor-run winding° If the motor does not
"hum," (attempt to start) the run winding is probably open. A continuity check (power off and coupler separated)
between the blue and white motor lead should indicate low resistance. If an open circuit is indicated, replace
the motor.
3. If no voltage at "A," (Figure 3!), then check for voltage at the output side of timer as shown in Figure 32
Position "B."
4. Continuous voltage at BLU-ORG terminal indicates that timer switch is OK, and the trouble is in the start relay,
wiring, or wiring connections.
If there is no voltage at the BLU-ORG terminal check for voltage at the input side of timer,. (Refer to wiring
diagram for the correct timer terminaL)If power is found at the input terminal then the diner is at fault. If
voltage is not present at input terminat, then problem is somewhere in circuit ahead of timer.. Trace circuit for
cause and make the necessary repairs,.
