TROUBLESHOOTING TEST PROCEDURES

Test #1 - 120 VAC Electrical Supply

Check for 110-125 VAC to the control board.

1. With the washer off but connected to the AC outlet, measure the AC voltage between Pins 2

and 1 at connector P5.

2. If 110-125 VAC is present, continue with the remaining Troubleshooting Tests as needed. If

voltage is not present, check circuit breaker or fuse box, power cord connection at outlet and

washer.

Test #2 - Water Inlet & Dispenser Solenoid Valve Test

This test checks for 110 - 125 VAC to these valves, the electrical connections to the

valves, and the valves themselves.

A: Check the relays and electrical connections to the valves.

1. See the Service Tests and perform the

Water Inlet and Dispenser Valve Test. Each step in

the test activates a group of valves. The table shows where voltage measurements are to be

checked for each valve. The voltage should be from 110 VAC to 125 VAC.

2. If no voltage is present at any of these test points and the voltage at the wall outlet is normal

(See Test No. 1), the control board has a faulty relay. Replace the control board.

If this test is OK, go to B.

B: Check the individual solenoid valves.

1. Unplug the washer and disconnect connectors P5 and P6 from the control board before check-

ing the resistance. Make the checks at contacts shown.
