GE Washer Error Code E23: Drain Pump Motor Failure... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) controls the drain pump motor via a relay. The MCU monitors the drain pump motor's current draw. If the current draw is out of range (either too high or too low), the MCU will generate an E23 error code. Voltage is supplied via a 120V AC circuit through the control board to the drain pump motor.

Symptoms:

The GE washer displays an E23 error code. The washer may not drain properly, leaving water in the tub. The drain pump may not be running or may be making unusual noises. The wash cycle may stop prematurely.

Possible Causes:

Drain pump blockage with debris (lint, socks, etc.)
Faulty drain pump motor
Wiring harness issue between the MCU and drain pump
Defective MCU (Main Control Unit) relay for the drain pump
Clogged drain hose restricting water flow
Voltage supply issue to the drain pump

Solution:

1

Unplug the washer from the power outlet.
2

Locate the drain pump (typically at the bottom rear or front of the washer) and inspect for any visible obstructions.
3

Disconnect the drain hoses from the pump. Check for clogs in the hoses.
4

Use a multimeter to test the drain pump motor windings for continuity. A reading of infinity or near zero indicates a faulty motor. Refer to the tech sheet for specific resistance values.
5

Inspect the wiring harness and connectors leading to the drain pump. Look for loose connections, corrosion, or damaged wires. Repair or replace as needed. A 1/4-inch nut driver may be needed to access connectors.
6

Check the voltage supply to the drain pump during the drain cycle. You should measure approximately 120V AC.
7

If all other components test good, the MCU may be faulty and require replacement.

Safety Warning:

Disconnect power to the appliance before performing any repairs. High voltage is present inside the washer. Use proper Lock-Out/Tag-Out (LOTO) procedures to prevent accidental energization.

Prevention:

Regularly clean the lint filter. Periodically inspect the drain pump area for debris. Avoid overloading the washer with excessive laundry.

Expert Tip:

Some GE washers have a service mode that allows you to manually activate the drain pump. This can be useful for troubleshooting. Consult the service manual for the specific service mode entry sequence for your model. Typically, it involves pressing a sequence of buttons on the control panel in a specific order, such as pressing Start, then Temp, then Power rapidly. This lets you isolate the pump and see if it runs under direct command.

Frequently Asked Questions

•What is the typical resistance range I should expect when testing a good drain pump motor?

The typical resistance range for a good drain pump motor varies depending on the specific model, but generally falls between 5 to 20 ohms. Consult the washer's service manual or technical data sheet for the exact specification.

•How do I access the drain pump on my GE washer if it's located at the bottom front?

Typically, you'll need to remove the front panel of the washer. First, disconnect power. Then, look for screws along the bottom edge or sides of the front panel. Once the screws are removed, the panel should slide or tilt away, providing access to the drain pump. You may need a 5/16-inch socket or nut driver.

•If the drain pump is getting 120V AC but still not running, can I assume the pump is bad?

Yes, if the drain pump is receiving the correct voltage (approximately 120V AC) during the drain cycle and it is not running or making unusual noises, it's highly likely that the drain pump motor itself is faulty and needs to be replaced. However, confirm there are no obstructions inside the pump housing first.
