GE Washer E3 Error Code: Reset Button Combination for... | appliancefaults.com

Technical Background:

The E3 error code on GE 2025 washer models typically indicates an issue with the door lock circuit. The MCU (Main Control Unit) monitors the voltage at the door lock switch. When the door is closed and locked, the switch should provide a closed circuit, signaling the MCU to allow the wash cycle to begin. A break in this circuit, a short, or incorrect voltage readings trigger the E3 error. The MCU detects this abnormal voltage (usually a 5V DC signal is used for sensor monitoring) and throws the error.

Symptoms:

My GE washer displays an E3 error code. The door seems to be locked, and the machine won't start. I've tried unplugging it, but the error comes back when I plug it back in. The door might not be latching correctly. I've noticed it a couple of times when it seemed like I had to push it hard to get it closed.

Possible Causes:

Door lock switch malfunction
Wiring harness issue between door lock and main control board
Main control board (MCU) failure
Foreign object obstructing door lock mechanism
Incorrect door alignment triggering the sensor

Solution:

1

Disconnect power to the washer by unplugging it from the outlet or turning off the breaker at the breaker panel.
2

Inspect the door lock mechanism for any visible obstructions or damage. Remove any foreign objects.
3

Using a multimeter, check the continuity of the door lock switch when the door is closed. It should show continuity. No continuity indicates a faulty switch.
4

Check the wiring harness between the door lock and the main control board for loose connections or damaged wires. Use a wiring diagram to verify correct pin assignments.
5

With the power disconnected, carefully disconnect and reconnect the connectors to the main control board to ensure a good connection.
6

If the wiring and door lock switch are good, the main control board may be faulty. Replacement is necessary. Ensure the new board is the correct part number for the model.
7

After addressing the potential cause, attempt to reset the error code. For 2025 GE washer models, try pressing and holding the START and POWER buttons simultaneously for 5 seconds. Reconnect power and test.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Capacitors in the control board can hold a charge even after the power is disconnected. Use caution when working around electrical components. Use proper Lock Out/Tag Out procedures (LOTO) to ensure the unit is not powered on accidentally during repair. High voltage (120V AC) is present in the appliance.

Prevention:

Regularly inspect the door lock area for obstructions. Avoid slamming the door. Ensure the washer is level to prevent door misalignment. Check hoses for leaks which might affect the electronics.

Expert Tip:

On some GE models, you can enter service mode by pressing and holding the START button, then pressing the POWER button, releasing both, and then quickly pressing START again. This might allow you to run diagnostics and clear error codes. However, proceed with caution, as incorrect settings can cause further issues.

Frequently Asked Questions

•Where can I find the wiring diagram for my GE 2025 washer model?

The wiring diagram is usually located inside the control panel housing or on the back of the washer. You may need to remove a panel to access it. Alternatively, you can search online using the model number of your washer.

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

Set your multimeter to the continuity setting (usually indicated by a sound wave symbol or an Ohm symbol). With the washer unplugged, place one probe on each of the switch terminals. When the door is closed and the lock engaged, the multimeter should beep or display a low resistance value, indicating continuity.

•If the main control board is faulty, where can I purchase a replacement?

You can purchase a replacement main control board from appliance parts retailers online, local appliance parts stores, or directly from GE appliance parts. Make sure to verify the part number matches your washer's model number before ordering.
