GE Top Load Washer Not Draining: Troubleshooting Guide -... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) controls the drain pump motor by sending 120V AC when the water level sensor and lid switch confirm conditions are met. Voltage paths must be complete.

Symptoms:

The GE top load washer fills with water and completes the wash cycle, but the water remains in the tub. The washer does not proceed to the drain or spin cycle.

Possible Causes:

Clogged drain pump filter
Kinked or blocked drain hose
Faulty drain pump motor
Defective lid switch
Failed pressure switch
Malfunctioning main control board (MCU)

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Inspect the drain hose for kinks or obstructions. Remove the hose from the drain standpipe and check for clogs.
3

Locate the drain pump (typically at the bottom rear of the washer) and access the drain pump filter. Clean the filter of any debris.
4

Using a multimeter, check for 120V AC at the drain pump terminals during the drain cycle. If voltage is present but the pump isn't running, the pump motor is likely faulty.
5

Check the lid switch for continuity using a multimeter. The switch should show continuity when the lid is closed. Replace if faulty.
6

Test the pressure switch for proper operation. Use a multimeter to verify the switch changes state when the tub is empty versus full.
7

If all other components test good, the main control board (MCU) may be defective and require replacement.

Safety Warning:

Always disconnect the power supply to the appliance before performing any repairs. Use caution when working with electrical components. High voltage can cause serious injury or death. Follow Lock Out Tag Out (LOTO) procedures.

Prevention:

Regularly clean the drain pump filter every 3-6 months to prevent clogs. Avoid overloading the washer to prevent excessive lint buildup.

Expert Tip:

Some GE washers have a diagnostic mode. To access, typically you press and hold Start/Pause and then press Power On. Follow the service manual sequence for the specific model to initiate diagnostics and check error codes.
