GE Washer E3 Error Code During Spin Cycle: Troubleshootin... | appliancefaults.com

Technical Background:

The MCU monitors the motor speed and lid lock status. The E3 error indicates the MCU has detected an issue with the motor's ability to reach or maintain the expected spin speed, or a lid lock malfunction. Voltage paths include 120V AC to the motor and 5V DC to the lid lock sensor.

Symptoms:

The GE washer displays an E3 error code on the control panel during the spin cycle. The drum may not spin, or the spin cycle may stop abruptly. The washer may also be making unusual noises.

Possible Causes:

Unbalanced load in the washer drum.
Obstruction preventing the drum from spinning freely.
Faulty lid switch or lid lock mechanism.
Defective motor control unit (MCU).
Wiring harness issue between the MCU and the motor.
Failed motor or motor windings.

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Check for an unbalanced load. Redistribute the clothes evenly in the drum.
3

Inspect for obstructions between the inner and outer tubs. Remove any visible items.
4

Examine the lid switch or lid lock. Use a multimeter to test for continuity when the lid is closed. Replace if faulty.
5

Locate the MCU. Check the wiring harness for any loose connections or damage. Repair or replace as needed. Use a 1/4-inch nut driver to remove the control panel for access.
6

With the washer unplugged, use a multimeter to check the motor windings for continuity. A reading of infinity indicates a failed winding.
7

If the wiring and motor are good, suspect a faulty MCU. Replacement is usually required. Take photos of the wiring before disconnecting.

Safety Warning:

Disconnect power to the appliance at the breaker panel before servicing. Lock Out / Tag Out (LOTO) procedures should be followed to prevent accidental energization. High voltage is present inside the washer's control panel. Do not touch any components with wet hands.

Prevention:

Avoid overloading the washer. Regularly check and clean the lint filter. Do not wash items that could cause excessive imbalance. Ensure the washer is level.

Expert Tip:

Some GE washers have a service mode. Consult the service manual for your specific model. You can often run diagnostic tests through the service mode to pinpoint the issue. The typical entry to service mode involves pressing specific buttons in a sequence, such as "Start, Temp, Signal, Power".

Frequently Asked Questions

•Where is the lid switch located on my GE washer?

The lid switch is typically located near the lid hinge, either on the cabinet or on the lid itself. It's usually a small plastic component with wires connected to it.

•How do I test the motor windings with a multimeter?

Unplug the washer. Locate the motor and disconnect the wiring harness. Set your multimeter to the Ohms setting. Place the multimeter probes on the motor terminals. A reading close to zero indicates continuity. An open circuit (infinity) indicates a failed winding.

•What is the part number for a replacement MCU for a GE washer?

The MCU part number varies depending on your specific GE washer model. You will need to find the model number of your washer, usually located on a sticker inside the door or on the back panel. Then, search online using the model number and 'MCU replacement' to find the correct part.
