Amana Washer Error Code F5E1: Lid Switch Not Locking... | appliancefaults.com

Technical Background:

The MCU monitors the lid switch position through a low-voltage DC circuit. When the start button is pressed, the MCU sends a 120V AC signal to the lid lock actuator to engage the lock. The MCU then verifies the lock is engaged via a feedback signal from the lid switch. If the MCU doesn't receive the confirmation signal or the lock isn't achieved within a specific timeframe, it throws the F5E1 error. Voltage paths include 120V AC to the actuator and 5V DC for the lid switch sensor feedback.

Symptoms:

The washer displays an F5E1 error code. The lid does not lock, and the wash cycle will not start or pauses mid-cycle. You might hear clicking sounds from the lid area.

Possible Causes:

Lid switch failure
Lid lock actuator malfunction
Wiring harness damage between the MCU and lid switch
MCU (Main Control Unit) failure
Obstruction preventing lid lock engagement

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Inspect the lid switch and lid lock mechanism for any visible damage or obstructions.
3

Using a multimeter, check the lid switch for continuity when the lid is closed. It should show continuity.
4

Verify 120V AC is present at the lid lock actuator during the lock cycle. If not, check the wiring harness back to the MCU.
5

Check the wiring harness for continuity and shorts using your multimeter. Repair or replace any damaged wires.
6

If the wiring and lid switch are good, replace the lid lock actuator.
7

If the issue persists after replacing the actuator, the MCU may be faulty and require replacement.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures must be followed. Some components carry 120V AC, which can cause serious injury or death.

Prevention:

Avoid slamming the lid shut. Ensure the washer is level to prevent unnecessary strain on the lid lock mechanism. Periodically inspect the lid area for debris or obstructions.

Expert Tip:

Enter service mode by pressing and holding the start button for 3 seconds, then simultaneously pressing the cycle selection knob twice to the right. This may allow you to bypass the lock and test other functions, or run diagnostic tests.

Frequently Asked Questions

•What is the part number for the lid switch assembly on this Amana washer model?

The lid switch assembly part number varies depending on the specific sub-model of your Amana washer. Check the model and serial number on the appliance and cross-reference with a parts supplier website, such as AppliancePartsPros or RepairClinic, to find the correct part number.

•How can I test the MCU to determine if it is the source of the F5E1 error?

Testing the MCU directly requires advanced diagnostic skills and specialized equipment. As a preliminary test, you can visually inspect the MCU board for burnt components or signs of water damage. Otherwise, confirming the MCU failure typically involves eliminating all other possible causes first, such as the lid switch, wiring, and actuator.

•Where can I find a wiring diagram for this specific Amana washer model?

Wiring diagrams are often located inside the washer cabinet, usually taped to the back panel or inside the control panel. You can also try searching online using the model number to find a downloadable PDF service manual, which typically includes wiring diagrams.
