SECTION 4: TROUBLESHOOTING

COMMON PROBLEMS (DOMESTIC UNITS)

Problem: Machine runs with door open.

1.Door switch shorted. With machine off, open doors, and with both wires to door switch unplugged, measure continuity between wires on switch. If there is continuity, replace the switch.

2.Faulty wash relay (wash relay contacts welded closed). Turn machine off, if wash relay doesn't release, replace contactor.

3.Faulty control relay. With power off, remove WHITE/RED & BLACK/YELLOW wires from control relay terminals #9 & #6. If there is continuity, replace relay.

Problem: Low pumped water pressure.

1.Water level is too low. Increase fill time on cam timer, or decrease drain timer, or increase incoming water pressure.

2.Sump strainer clogged. Clean strainer.

3.Wash arms clogged. Clean arms and jets.

4.Obstruction in pump housing or wash manifold. Disassemble and clear.

5.Pump impeller worn or broken. Replace the pump impeller.

Problem: Sanitizer pump doesn't run during the cycle or through the use of the prime switch.

1.Loose motor terminal wire. Tighten connections.

2.Faulty sanitizer pump motor. If you read 120V at the sanitizer motor terminals during the sanitizer feed cycle, replace the motor.

Problem: Machine keeps tripping the service breaker.

1.Power supply shorted to ground. Check for loose wires or burned connections.

2.Faulty door switch or detergent safety switch. Check for loose or wet connections at switch and at wire connectors. Bypass switch to verify that switch is problem; replace if required.

3.Pump impeller jammed. Clear impeller.

4.Wash pump motor faulty. Check motor voltage and amp load. If amp load is over 12 amps, replace the motor.

5.Circuit breaker is too small. Replace with properly sized breaker. Refer to the data plate.

Problem: Machine will not drain.

1.Loose wire connection. Tighten wires to timer drain microswitch.

2.Drain hole/strainer obstructed. Clear obstructions.

3.Not enough time to drain. Adjust fill cam on timer and/or the drain cam.

4.Drain linkage binding. Repair drain parts.

5.Faulty drain microswitch on timer. With power off and the drain cam on the timer in the home position, remove the WHITE/YELLOW wire from the microswitch.

6.Faulty drain microswitch on timer. Measure the continuity between the ORANGE wire on the microswitch and the tab that the WHITE/ YELLOW wire is attached onto. If there is no continuity, replace the microswitch.

7.Drain solenoid defective. Check for voltage at solenoid valve during the drain cycle. Replace if voltage is present.

Problem: Sanitizer pump runs continuously.

1.Shorted sanitizer microswitch on cam timer. If there is not 120V between the ORANGE and GREY wires on the sanitiza- tion pump motor microswitch when switch is out of the home position, replace the switch.

2.Shorted prime switch. If there is not 120 volts between GREY and WHITE/RED wires to prime switch, replace the switch. Sanitizer pump does not run during the cycle, but runs when primed.

3.Loose or broken wire. Tighten connections to microswitch.

4.Faulty sanitizer microswitch on cam timer. When sanitizer cam is in home position, measure voltage between ORANGE and GREY wires on the microswitch. If 120V, replace switch.
