Amana Washing Machine Error Code dL: Lid Lock... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) sends a signal to the lid lock solenoid to engage the lock. A feedback signal is sent back to the MCU to confirm the lid is locked. The 'dL' error indicates that the MCU is not receiving the expected feedback signal, or the lock is not engaging within the allotted time. Voltage is typically 5V DC for the signal and 120V AC for the lid lock motor (depending on model).

Symptoms:

The washing machine displays the 'dL' error code on the control panel. The lid may not lock or unlock, and the washing machine will not start or continue its cycle.

Possible Causes:

Faulty lid lock switch assembly.
Wiring harness damage between the lid lock and the MCU.
Obstructed or misaligned lid strike.
Defective Main Control Unit (MCU).
Loose wire connections at the lid lock or MCU.

Solution:

1

Unplug the washing machine from the 120V AC outlet.
2

Inspect the lid lock assembly for physical damage or obstructions.
3

Check the wiring harness and connectors leading to the lid lock for continuity and secure connections. Use a multimeter to check for voltage (typically 5V DC) at the lid lock connector when the machine attempts to lock.
4

Verify the lid strike is properly aligned with the lid lock receiver. Adjust if necessary.
5

If the wiring and lid strike are good, replace the lid lock switch assembly.
6

As a last resort, replace the Main Control Unit (MCU). Ensure the new MCU is properly programmed (if required).
7

Plug the washing machine back into the 120V AC outlet and test the operation.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Use proper Lock Out Tag Out (LOTO) procedures to ensure the appliance is not accidentally powered on during service. Some components may carry 120V AC even when the machine is off; exercise caution.

Prevention:

Avoid slamming the lid, which can damage the lid lock mechanism. Regularly inspect the lid strike and ensure it is properly aligned. Check for any signs of wear or damage to the wiring harness.

Expert Tip:

Some Amana washing machines have a service mode. To enter it, try pressing and holding the Start/Pause button while simultaneously pressing another button like Cycle Signal for 3 seconds. This may allow you to bypass the lid lock for testing purposes.

Frequently Asked Questions

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

Set your multimeter to the continuity setting. With the lid closed and the machine attempting to lock, you should see continuity between the appropriate terminals on the lid lock switch. Refer to the wiring diagram for the specific terminals.

•What is the part number for the lid lock assembly on my Amana washing machine?

The part number varies depending on your specific model number. You can find the correct part number by searching online using your model number or by consulting a parts distributor.

•How do I know if the MCU is the problem?

The MCU should be suspected only after verifying that the lid lock assembly, wiring, and lid strike are all functioning correctly. Replacing the MCU is generally the last resort, as it is the most expensive component.
