Operating and Over Fill Pressure Switch Test
Check the hose connections between each pressure switch in the console and the pressure dome
attached to the tub.
If hose connections are good, check the Operating Pressure Switch as follows:
•
Press HEAVY DUTY then START to start a cycle. Let the unit fill and see if the operating
pressure switch turns off the water.
•
Check the voltage across Pins P and V of the operating pressure switch. If 12VDC is present,
the water level switch has opened the switch.
•
If no voltage is present and the water has filled the tub to a visible level (above the nutate
plate), stop the cycle and replace the operating pressure switch.
If hose connections are good and the Operating Pressure Switch is good, check the Overfill
Pressure Switch as follows- NOTE - PERFORM THE FOLLOWING STEPS IN THIS ORDER:
•
Pull the hose off the Operating Pressure Switch so that the washer can fill beyond the operating
switch trip point.
•
Press HEAVY DUTY then START to start a cycle. Let the unit fill and see if the overfill pres-
sure switch will trip.
•
Check the voltage across pins P and V of the overfill pressure switch. If 120VAC is present,
the water level has opened the switch. This should also shut off the water inlet valves and give
an FL indication on the 7-segment display.
•
If no voltage is present and the water has filled the tub to an overfill level, stop the cycle and
replace the overfill pressure switch. Drain out the water by starting an EXTEND SPIN
cycle. Do not allow the wash plate to nutate under water.
Drain/Recirculation Test
Perform the following checks if the unit fails to drain or recirculate.
•
Check that there is power to the washer.
•
Check that the pump connection (P5) to the motor controller is properly installed.
•
Check pump motor windings and wiring harness by removing the connector (P5) from the
motor controller board.
Recirc to Neutral
10 - 12
Ω
P5-3 (RD/BU) to P5-1 (WH)
Drain to Neutral
10 - 12
Ω
P5-2 (TN/YL) to P5-1 (WH)
Recirc to Drain
20 - 25
Ω
P5-3 (RD/BU) to P5-2 (TN/YL)
•
If the winding measurements are much higher than shown above, a problem exists in the
motor winding or in the connection between the motor controller and the motor. Check the
resistance at the pump motor.
If the resistance is not within this range, check for continuity between the connector and the
sensor.
