Hotpoint Washer E3 Error: Lid Lock Troubleshooting Guide... | appliancefaults.com

Technical Background:

The E3 error code on a Hotpoint washer typically indicates a problem with the lid lock circuit. The MCU (Main Control Unit) sends a voltage signal to the lid lock actuator, which engages the lock. The MCU then verifies the lock status via a feedback signal. If the feedback signal is missing or incorrect, the MCU displays the E3 error.

Symptoms:

The homeowner observes that the Hotpoint washer's lid lock clicks three times and then displays an E3 error code on the control panel.

Possible Causes:

Lid switch failure
Wiring harness damage (Lid switch circuit)
MCU (Main Control Unit) malfunction
Obstruction preventing lid lock engagement
Lid lock actuator failure
Loose connection at the lid switch or MCU

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the lid switch assembly. This is usually under the top panel, near the lid hinge.
3

Inspect the wiring harness for any visible damage. Use a multimeter to check continuity of the wires.
4

Use a 5/16-inch nut driver to remove the lid switch assembly.
5

Test the lid switch with a multimeter. The switch should show continuity when the lid is closed and no continuity when open. If not, replace the lid switch.
6

Inspect the lid lock actuator for any visible damage. Replace if needed.
7

Reassemble the washer and test its operation.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before attempting any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental re-energizing of the circuit. High voltage is present inside the appliance; exercise caution.

Prevention:

Avoid slamming the washer lid. Regularly inspect the lid switch area for debris or obstructions. Ensure the washer is level to prevent excessive vibration that could damage wiring.

Expert Tip:

Some Hotpoint washers have a service mode. Refer to the technical sheet inside the control panel for specific instructions on how to enter the service mode and retrieve detailed error codes. This can provide further insights into the cause of the E3 error.
