If there is too much water or foam in the washer, the overflow contact on the pressure switch closes.
If the valves are open, they automatically close and the drain pump is switched on for at least 30
seconds. To unlock the door, press POWER.
- Check the drain hose and make sure it is not plugged or kinked.
- Unplug washer or disconnect power; if water still flows into the washer, the water inlet
valve must be replaced.
- Make sure that all wire harness connections to the drain pump, pressure switch, water inlet
valves, and CCU (VCH7, DP2, PR6, and DI6 cavities) are not broken or with wires detached,
and that connector internal pins are visible.
- Check continuity from the following components:
A) Water inlet valve connectors (double and single) and the CCU (VCH7 and DI6 cavity connectors)
B) Pump connector wires to CCU (DP2 cavity connector)
C) Pressure switch connector wires to CCU (PR6 cavity connector).
- If the continuity diagnosis failed, the Main Harness must be replaced.
- Check the resistance of the inlet valve (double & single). See page 7.
- Make a visual inspection on the inlet valve to identify scratches on its plastic structure.
- Check the resistance to the drain pump. See page 7.
- Disassemble the housing pump from the pump motor.
- Check that the impeller is not detached from the motor shaft or is misaligned from
the pump shaft.
- Check the pressure switch for proper operation. Remove hose from pressure switch.
Dislodge any debris buildup in the hose inside the outer tub. Debris inside the hose will
not allow the switch to sense a pressure change.
- Check pressure switch operation. Remove pressure switch. Blowing air through the opening,
the two internal switches are heard one by one.
- Make continuity test to the Pressure SW. See page 7.
- Plug in washer or reconnect power.
- Verify the washer operation by performing the Diagnostic Test cycle. See page 5.
- After the diagnostic test has finished, unplug washer or disconnect power and wait 15 seconds
WATER TEMPERATURE SENSOR ERROR
If the water temperature sensor (NTC) value is out of range (23°F to 217°F
[-5°C to 103°C]) during the water-heating step of the WASH cycle.
- Unplug washer or disconnect power.
- Make sure that connections to water heater & CCU (TH2 & HE2 cavities)
connectors are not broken or with wires detached, and that connector internal
pins are visible.
- Check continuity from the water heater sensor (black wires) to CCU
(TH2 cavity) connector.
- Check the resistance of heating element. See page 7.
- Check the resistance of the water sensor. See page 7.
- Verify the washer operation by running the Diagnostic Test cycle. See page 5.
- After the diagnostic test has finished, unplug washer or disconnect
power and wait for 15 seconds.
