GE Profile Washer E3 Error: Troubleshooting and... | appliancefaults.com

Technical Background:

The E3 error code on a GE Profile washer typically indicates a problem with the lid switch circuit. The Main Control Unit (MCU) monitors the voltage signal from the lid switch to confirm that the lid is closed before initiating or continuing the wash cycle. If the MCU does not receive the correct signal (open or short circuit), it triggers the E3 error. Voltage is typically 5V DC in the lid switch circuit.

Symptoms:

The GE Profile washer displays an E3 error code on the control panel. The washer may not start, or it may stop mid-cycle.

Possible Causes:

Lid switch malfunction.
Wiring harness damage to the lid switch.
Main Control Unit (MCU) failure.
Loose wire connections at the lid switch or MCU.
Obstruction preventing proper lid closure.

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the lid switch, usually near the door frame. Visually inspect for damage.
3

Using a multimeter, test the lid switch for continuity when the lid is closed. It should show continuity.
4

Check the wiring harness connected to the lid switch for any breaks or loose connections. Use a wiring diagram to identify the correct wires.
5

Inspect the door strike for damage and ensure it aligns properly with the lid switch.
6

If the switch tests bad, replace it. Order a new lid switch assembly.
7

Reconnect power. If the error persists, suspect a faulty MCU and consider replacing the MCU (Main Control Unit).

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Lockout/Tagout (LOTO) procedures should be followed. The washer contains high voltage components that can cause serious injury or death.

Prevention:

Periodically inspect the lid switch area for obstructions or damage. Avoid slamming the washer lid. Ensure the washer is level to prevent excessive vibration that can damage wiring connections.

Expert Tip:

Some GE Profile washers have a diagnostic mode or calibration routine that can be accessed through a specific button sequence. Consult the service manual for your specific model. A common sequence is press and hold START and TEMP DOWN simultaneously for 3 seconds. This can sometimes clear the error code and recalibrate the lid switch sensor.

Frequently Asked Questions

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

The lid switch is typically located near the top of the washer cabinet, close to the lid hinge. It might be a magnetic reed switch or a mechanical switch.

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

Disconnect power. Set your multimeter to the continuity setting (beep symbol). Place one probe on each terminal of the lid switch. With the lid closed (or the switch manually activated), the multimeter should beep, indicating continuity.

•If I replace the lid switch and the E3 error persists, what should I do?

If the error persists after replacing the lid switch, the problem may lie with the wiring harness between the switch and the MCU, or with the MCU itself. Check the wiring for continuity and shorts to ground. If the wiring is good, the MCU may be faulty and require replacement.
