GE Washer Error Code E3: Troubleshooting and Diagnostic... | appliancefaults.com

Technical Background:

The E3 error code on a GE washer typically indicates a problem with the draining system. The MCU monitors the drain pump circuit and the water level using the pressure switch. If the MCU detects a drain fault (such as the pump not operating or the water level not decreasing as expected), it will trigger the E3 error and stop the wash cycle.

Symptoms:

The GE washer displays an E3 error code on the control panel. The washer may not drain properly, or it may drain very slowly. You might also hear a humming noise from the drain pump area, or no noise at all.

Possible Causes:

Obstruction in the drain hose
Clogged drain pump filter
Defective drain pump motor
Pressure switch malfunction
Faulty wiring harness or connections to the drain pump or pressure switch
Main Control Unit (MCU) failure

Solution:

1

Unplug the washer from the outlet.
2

Inspect the drain hose for kinks or clogs. Remove any obstructions.
3

Access the drain pump filter (usually located at the bottom front of the washer) and clean it thoroughly.
4

Check the drain pump for voltage. Set your multimeter to measure AC voltage. During the drain cycle, you should read approximately 120V AC at the pump terminals.
5

If no voltage is present at the pump, inspect the wiring harness and connections between the MCU and the drain pump for any damage or loose connections.
6

Check the pressure switch using a multimeter. The switch should change state (open or closed) as the water level changes. Replace if defective.
7

If all other components check out, the MCU may be faulty and require replacement. This should be performed by a qualified technician.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed by qualified technicians when servicing appliances. High voltage is present when the appliance is powered on.

Prevention:

Regularly clean the drain pump filter (every 3 months or as needed). Avoid overloading the washer with clothes. Use the correct amount of detergent. Inspect the drain hose periodically for kinks or damage.

Expert Tip:

To enter the diagnostic test mode on some GE washers, press and hold the Start/Pause button, then simultaneously press and release the Temp and Soil Level buttons. Release all buttons. This will allow you to run diagnostic tests and clear error codes. Specific button sequences vary by model.

Frequently Asked Questions

•How do I access the drain pump filter on my GE washer?

The drain pump filter is typically located behind a small access panel at the bottom front of the washer. You may need a flathead screwdriver to open the panel. Have a shallow pan ready to catch any water that spills out when you remove the filter.

•What is the proper resistance reading for a good drain pump motor?

The resistance of the drain pump motor windings typically ranges from 10 to 30 ohms. Use a multimeter to measure the resistance across the pump terminals. Consult the specific service manual for your model for precise values.

•Where is the pressure switch located and how can I test it?

The pressure switch is usually located near the bottom of the tub, connected to a small hose. Disconnect the hose and blow gently into the switch. You should hear a click. Use a multimeter to check for continuity across the switch terminals in both the empty and full tub states. The switch should change state as the air pressure changes.
