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

Technical Background:

The MCU controls the entire wash cycle, including the drain pump operation. The MCU receives input from the water level sensor and lid switch. If the water level sensor indicates water is still present, or if the lid switch is open, the MCU will prevent the drain pump from activating. The MCU sends 120V AC to the drain pump to activate it.

Symptoms:

The GE top load washer fills with water and washes clothes, but then fails to drain the water. The clothes remain wet in the tub, and the washer does not proceed to the spin cycle. The user may hear a humming noise, or no noise at all, during the drain cycle.

Possible Causes:

Clogged drain pump filter
Kinked or blocked drain hose
Defective drain pump
Failed lid switch
Faulty water level sensor
Malfunctioning MCU (Main Control Unit)

Solution:

1

Unplug the washer from the 120V AC outlet and turn off the water supply.
2

Inspect the drain hose for kinks, clogs, or improper height (should be 30-96 inches above the floor). Disconnect the hose and flush it with water.
3

Locate the drain pump (usually at the bottom rear of the washer). Access it by removing the rear panel using a 1/4-inch nut driver.
4

Check the drain pump filter for debris. Remove the filter and clean it thoroughly.
5

Use a multimeter to check the drain pump for continuity. A reading outside the expected range (typically 10-20 ohms) indicates a faulty pump. Replace if needed.
6

Verify the lid switch is functioning correctly. With the washer unplugged, use a multimeter to check continuity when the lid is closed. Replace if faulty.
7

If the above steps fail, the MCU may be faulty. Replacement should be done by a qualified technician.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any repairs. Use proper lockout/tagout (LOTO) procedures to prevent accidental energization. Be aware of high voltage (120V AC) when testing electrical components.

Prevention:

Regularly clean the drain pump filter (every 3 months) to prevent clogs. Avoid overloading the washer, as excessive lint can contribute to drain pump blockages. Inspect the drain hose periodically for kinks or damage.

Expert Tip:

Some GE washers have a service mode that allows you to manually activate the drain pump. Consult the service manual for your specific model to access this mode and test the pump's functionality.

Frequently Asked Questions

•Where is the drain pump filter located on my GE top load washer?

The drain pump filter is typically located at the bottom front or rear of the washer. You'll need to remove an access panel to reach it. Refer to your washer's user manual for the exact location and removal instructions.

•How do I test the water level sensor?

Testing the water level sensor usually requires a multimeter and some knowledge of its specific resistance values at different water levels. Refer to the service manual for the correct testing procedure and resistance ranges. It often involves disconnecting the sensor and measuring resistance across specific terminals as you manually adjust the water level.

•What is the proper drain hose height?

The drain hose should be installed so that the top of the hose is between 30 and 96 inches above the floor. This prevents siphoning and ensures proper drainage. If the hose is too low, the washer may continuously drain, and if it's too high, it may not drain effectively.
