Admiral Washer Lid Lock Bypass: Is It Possible with a... | appliancefaults.com

Technical Background:

Modern washing machines use a lid lock system for safety. The Main Control Unit (MCU) monitors the lid lock switch and controls the voltage to the lid lock solenoid. A signal from the lid lock is required by the MCU before the washer will start a cycle. Bypassing the lid lock with a jumper wire can be dangerous and may damage the MCU.

Symptoms:

The Admiral washer won't start, displays an error code related to the lid lock, or the lid lock doesn't engage or disengage.

Possible Causes:

Faulty lid lock switch
Broken wire harness to the lid lock
Malfunctioning Main Control Unit (MCU)
Damaged lid strike
Loose connection at the lid lock or MCU
Tripped thermal fuse in the lid lock assembly

Solution:

1

Disconnect power to the washer at the breaker panel. Verify 120V AC is off at the outlet using a multimeter.
2

Locate the lid lock assembly. Usually accessible by removing the top panel (secured by screws at the rear) or front panel.
3

Inspect the wire harness connecting to the lid lock for any visible damage, cuts, or loose connections.
4

Use a multimeter to check the continuity of the lid lock switch. With the lid closed (simulated latch), the switch should show continuity. Open, it should show open circuit.
5

If the wiring and switch check out, suspect a faulty MCU. Check the voltage supply to the lid lock from the MCU, refer to the wiring diagram (typically found inside the washer cabinet). You should find around 5V DC signal.
6

If the MCU is not sending the correct voltage to the lid lock, the MCU may need replacement.
7

After any repairs, reconnect the power and test the washer operation. Ensure the lid locks and unlocks properly during the wash cycle.

Safety Warning:

Disconnect power to the washer at the breaker panel before any troubleshooting. High voltage is present inside the appliance. Follow Lock Out Tag Out (LOTO) procedures.

Prevention:

Avoid slamming the lid. Regularly inspect the lid lock area for any signs of damage or wear. Ensure the washer is level to prevent excessive vibration that could damage the lid lock mechanism.

Expert Tip:

Many Admiral washers have a diagnostic mode. To enter, rapidly rotate the cycle selector knob clockwise three positions, then counter-clockwise two positions, then clockwise one position within a few seconds. This may allow you to read error codes without the need for special tools.

Frequently Asked Questions

•How do I find the wiring diagram for my Admiral washer?

The wiring diagram is typically located inside the washer cabinet, often attached to the back panel or inside the control panel. You may need a 1/4-inch nut driver to access it.

•What voltage should I expect to see at the lid lock switch when the lid is closed?

You should see a voltage signal from the MCU, typically around 5V DC, when the lid is closed and the lid lock is attempting to engage. If the lid lock is engaged, the multimeter should show continuity.

•If the lid lock is bypassed with a jumper wire, what are the potential risks?

Bypassing the lid lock can be dangerous. The washer can operate with the lid open, posing a safety hazard. It can also overload the MCU and cause permanent damage, requiring replacement of the entire control board.
