Maytag Washer Lid Lock Flashing and Won't Start:... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the lid lock switch to ensure the lid is closed and locked before initiating the wash cycle. A signal is sent from the MCU to activate the lid lock solenoid. If the MCU doesn't receive the correct feedback, it will prevent the washer from starting and display a flashing lid lock light.

Symptoms:

The Maytag washer's lid lock light is flashing, and the washer will not start a cycle. The machine appears unresponsive.

Possible Causes:

Faulty lid lock switch
Damaged wiring harness to lid lock
Failed main control board (MCU)
Obstructed drain pump
Lid switch not aligned properly

Solution:

1

Unplug the washer from the power outlet. Ensure the power cord is fully disconnected.
2

Access the lid lock switch, typically located under the top panel. You may need a 1/4-inch nut driver to remove screws.
3

Inspect the lid lock switch for physical damage. If visibly broken, replace the switch.
4

Check the wiring harness connecting to the lid lock for any breaks or loose connections. Use a multimeter to test for continuity in the wires. Repair or replace as needed.
5

Using a multimeter, test the voltage to the lid lock. You should see approximately 120V AC when the washer is attempting to lock. Use caution when working with live voltage.
6

If the voltage is present, but the lid lock is not engaging, the lock mechanism itself is likely faulty. Replace the entire lid lock assembly.
7

If no voltage is present at the lid lock and the wiring is good, check the main control board (MCU) for any signs of damage, such as burnt components. If damaged, replace the MCU.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. Working with electrical components involves risk of electric shock. If you are not comfortable working with electricity, consult a qualified appliance repair technician.

Prevention:

Avoid slamming the washer lid. Regularly check and clear the drain pump filter of debris. Ensure the washer is level to prevent excessive vibration which can damage components.

Expert Tip:

Some Maytag washers have a diagnostic mode. Entering this mode can provide error codes which can help pinpoint the problem. Typically, you can access the diagnostic mode by pressing a specific sequence of buttons (e.g., Start/Pause, then specific cycle buttons). Consult the service manual for your specific model for the correct sequence.

Frequently Asked Questions

•How do I access the lid lock switch on my Maytag washer?

Typically, you'll need to unplug the washer and remove the top panel. This usually involves removing screws at the rear of the washer. Once the screws are removed, the top panel can often be slid back and then lifted off. The lid lock switch will then be accessible.

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

First, unplug the washer. Disconnect the wiring harness from the lid lock switch. Set your multimeter to the continuity setting (ohm symbol). Check for continuity between the appropriate terminals on the switch when the lid lock is engaged (simulated by manually pushing the lock mechanism). Consult the wiring diagram for your specific model to identify the correct terminals.

•Where can I find the service manual for my Maytag washer model?

You can usually find the service manual by searching online using your washer's model number. Websites like AppliancePartsPros or RepairClinic often have service manuals available for download. You may need to create an account or pay a small fee to access them.
