GE Washer Beeping 3 Times with E3 Error: Troubleshooting... | appliancefaults.com

Technical Background:

The E3 error in GE washers typically indicates a problem with the door lock mechanism or the communication between the door lock and the Main Control Unit (MCU). The MCU monitors the door switch status. When it detects an anomaly, it throws an E3 error. Voltage is supplied to the door lock solenoid from the MCU through the wiring harness. A faulty switch will break this voltage path, causing the error.

Symptoms:

The GE washer stops mid-cycle and beeps three times. The display shows an E3 error code. The door might be locked or unlocked.

Possible Causes:

Door switch failure.
Wiring harness damage to the door switch.
Main Control Unit (MCU) failure.
Foreign object obstruction preventing proper door lock.
Lid lock solenoid malfunction.

Solution:

1

Disconnect power to the washer at the breaker panel. Verify no voltage with a multimeter.
2

Inspect the door switch for visible damage or obstructions. Remove any debris.
3

Check the wiring harness connected to the door switch for breaks, cuts, or loose connections.
4

Use a multimeter to test the door switch for continuity when the door is closed. It should show continuity when closed, and no continuity when open.
5

Replace the door switch if it fails the continuity test or is visibly damaged. Use a 1/4-inch nut driver for this.
6

If the door switch and wiring are good, suspect a Main Control Unit (MCU) failure. Replacement of the MCU may be necessary. This is best left to a qualified technician.
7

After repairs, restore power and test the washer through a full cycle.

Safety Warning:

Disconnect power to the appliance at the breaker panel before attempting any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. Some components may retain a high voltage even after the appliance is unplugged.

Prevention:

Avoid overloading the washer. Regularly inspect the door switch area for debris. Ensure the washer is level to prevent excessive vibration that could damage wiring.

Expert Tip:

Some GE washers have a service mode. To enter service mode, press and hold the Start/Pause button and then press and hold the Power button. Release both buttons. You may be able to retrieve more detailed error codes in this mode.

Frequently Asked Questions

•How do I test the door switch with a multimeter?

Set your multimeter to the continuity setting (usually indicated by a diode symbol or a sound wave symbol). Place one probe on each terminal of the door switch. With the door closed, you should hear a beep or see a reading close to zero ohms, indicating continuity. With the door open, you should see an open circuit (no continuity).

•Where can I find a replacement door switch for my GE washer?

You can find replacement door switches at most appliance parts retailers, both online and in physical stores. Be sure to have the model number of your washer handy to ensure you get the correct part. Search for "GE washer door switch [your model number]".

•What is the procedure for replacing the Main Control Unit (MCU)?

Replacing the MCU is a complex task. First, disconnect power. Then, carefully remove the washer's control panel. Locate the MCU and disconnect all wiring harnesses attached to it. Note the position of each harness for proper reinstallation. Replace the old MCU with the new one, reconnecting all the harnesses. Reassemble the control panel and test the washer. If you are not comfortable with electrical work, it is best to hire a qualified appliance technician.
