Amana Washer Lid Lock Clicking, Not Engaging:... | appliancefaults.com

Technical Background:

The Amana washer's main control unit (MCU) sends a 120V AC signal to the lid lock solenoid when a cycle requires the lid to be locked. The solenoid then engages a mechanism that physically locks the lid. The MCU also monitors a feedback signal from the lid lock to confirm that the lid is indeed locked. If the MCU doesn't receive the correct feedback voltage, or if the solenoid doesn't engage, the wash cycle will be interrupted, and the clicking sound may be heard due to repeated attempts to engage the lock.

Symptoms:

The Amana washer makes a clicking sound when attempting to start a cycle, particularly during the spin cycle or when the washer is trying to lock the lid. The lid remains unlocked, and the wash cycle doesn't initiate. The error might repeat continuously, with the clicking sound occurring multiple times. You might also notice the wash cycle won't start at all.

Possible Causes:

Faulty lid switch assembly.
Broken or damaged lid strike.
Wiring harness issue to the lid lock.
Main control board (MCU) malfunction.
Lid lock actuator failure.
Obstruction preventing the lid lock from engaging.

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the lid switch assembly, usually under the lid or behind the front panel. You may need a 1/4-inch nut driver or a Phillips head screwdriver.
3

Inspect the lid strike (the part that engages the lid lock) for damage. Replace if needed.
4

Using a multimeter, check the voltage to the lid lock assembly when the washer is supposed to be locking (should be around 120V AC). If no voltage is present, there's likely a wiring or main control board issue. Check the wiring harness for continuity using your multimeter.
5

If voltage is present but the lock isn't engaging, replace the lid lock assembly.
6

Reconnect power and test the washer operation.
7

If the problem persists after replacing the lid lock, suspect the main control board (MCU) and consider replacement or licensed technician diagnosis.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization. Some components may retain a high voltage charge even after the appliance is disconnected from power; use caution and appropriate safety equipment.

Prevention:

Avoid slamming the washer lid, as this can damage the lid strike or the lid lock mechanism. Ensure the washer is level to prevent excessive vibration, which can contribute to mechanical failures. Periodically inspect the lid area for obstructions or debris that might interfere with the lid lock operation.

Expert Tip:

Many Amana washers have a diagnostic mode. Accessing this mode often involves pressing a specific sequence of buttons on the control panel (example: Power-Start-Power-Start). Consult the service manual or search online for the specific sequence for your model. This can help pinpoint the exact fault code and component causing the issue.

Frequently Asked Questions

•What is the resistance value I should expect to see across the lid lock solenoid when it is functioning correctly?

Typically, a functional lid lock solenoid will have a resistance between 50 and 200 ohms. An open circuit indicates a failed solenoid, while a very low resistance could indicate a short.

•How can I manually test the lid lock mechanism?

While the power is disconnected, you can try to manually engage the lid lock mechanism (if accessible) with a small tool to see if it moves freely. Be careful not to force anything. If it feels stuck or obstructed, further inspection is needed.

•Where can I find the wiring diagram for my specific Amana washer model?

The wiring diagram is often located inside the washer cabinet, typically attached to the back panel or near the control panel. You may also be able to find it online by searching for the model number and 'wiring diagram'.
