Whirlpool Washer Error Code F5 E3: Lid Lock... | appliancefaults.com

Technical Background:

The F5 E3 error code indicates a problem with the lid lock mechanism. The main control unit (MCU) monitors the lid lock switch. When the start button is pressed, the MCU sends a 120V AC signal to the lid lock solenoid to engage. The lid lock switch then signals back to the MCU confirming that the lid is locked. If the MCU does not receive the confirmation signal or if it detects an unexpected change in the lid lock status, it will display the F5 E3 error.

Symptoms:

The Whirlpool washer displays an F5 E3 error code on the control panel. The lid is stuck in the locked position and cannot be opened, even after the wash cycle has completed. The washer will not start a new cycle while the error is present.

Possible Causes:

Faulty lid lock switch assembly.
Wiring harness issue between the main control unit (MCU) and the lid lock.
Defective main control unit (MCU).
Obstruction preventing the lid from properly engaging the lock mechanism.
Lid switch actuator arm broken.

Solution:

1

Unplug the washer from the 120V AC power outlet.
2

Inspect the lid lock assembly for any visible damage or obstructions.
3

Check the wiring harness connecting the lid lock to the MCU for loose connections or damaged wires. Use a multimeter to verify continuity.
4

Using a 1/4-inch nut driver, disassemble the top of the washer to access the lid lock switch. Disconnect the wire harness from the lid lock switch.
5

Using a multimeter, test the lid lock switch for continuity when the lid is closed and locked. A faulty switch should be replaced.
6

If the switch tests good, the MCU may be defective. Replacing the MCU will require programming and is best left to a qualified technician.
7

After repair, plug the washer back in and run a test cycle to ensure the error is resolved.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization. Some components may retain a charge even after the unit is unplugged. Use caution when working with electrical components, as 120V AC is present.

Prevention:

Avoid slamming the lid, as this can damage the lid lock mechanism. Regularly inspect the area around the lid for any debris or obstructions. Ensure the washer is level to prevent excessive vibration that could damage the lid lock.

Expert Tip:

Some Whirlpool washers have a diagnostic mode that can be accessed by pressing a specific sequence of buttons (usually involving the start/pause and power buttons). This mode can provide more detailed information about the error and allow you to manually unlock the lid. Refer to the service manual for the specific sequence for your model.

Frequently Asked Questions

•How do I access the diagnostic mode on my specific Whirlpool washer model?

The diagnostic mode access varies by model. Typically, you'll press a sequence of buttons like 'Start/Pause' and 'Power' in a specific order within a short timeframe. Consult the service manual or search online using your washer's model number for the precise sequence.

•What voltage should I expect to see at the lid lock solenoid when the washer is trying to lock the lid?

You should expect to see approximately 120V AC at the lid lock solenoid when the MCU is attempting to engage the lock. Use a multimeter set to AC voltage to test this, ensuring the washer is plugged in and attempting to start a cycle.

•If the lid lock switch tests good with a multimeter, what is the likelihood that the MCU is the problem?

If the lid lock switch tests good for continuity, and the wiring harness shows no issues, there is a strong possibility the MCU is the problem. However, consider other less common causes, such as a partially failed MCU relay. Replacing the MCU requires programming and is best handled by a professional.
