TROUBLESHOOTING TESTS
120VAC Electrical Supply
1.Check for 120VAC on the power cord connection to the line filter. If no AC power is present, replace the power cord.
2.Check for 120VAC on the line filter connection to the machine controller. If no AC power is present, replace line filter.
3.Check for 120VAC to the control board. With the washer off but connected to the AC outlet, measure the AC voltage between Pins 4 and 2 at connector P16.
•If 120VAC is present, continue with remaining Trouble Shooting Tests as needed.
•If voltage is not present, check circuit breaker or fuse box, power cord connection at outlet and washer.
Water Inlet and Dispenser Solenoid Test
This test checks for 120VAC to the water inlet and dispenser valves, the electrical connections to the valves and the valves themselves.
1.Check the electrical connections to the valves.
2.If any valve solenoid does not activate, measure the voltage across the pins as shown in the following table. The voltage should be equal to the incoming line voltage.
P13 - Pin # | P13 - Pin # | Function |
|
|
|
1 | 9 | cold water valve |
|
|
|
2 | 9 | hot water valve |
|
|
|
3 | 9 | detergent dispenser valve |
|
|
|
4 | 9 | fabric softener dispenser valve |
5 | 9 | bleach dispenser valve |
|
|
|
6 | 9 | fresh water valve |
|
|
|
3.If no voltage is present at any of these test points and voltage at the wall outlet is normal, the control board has a faulty relay. Replace the control board.
4.If voltage measurements are correct, check the individual solenoid valve. Unplug the washer and disconnect connector P13 from the control board.
5.Check the resistance at the contacts shown in the following table. If resistance is outside of range, replace the complete water inlet and dispenser assembly.
