Whirlpool Washer Door Lock Clicking 3 Times:... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) sends a voltage signal to the door lock assembly. The door lock motor then engages, locking the door. A sensor within the door lock assembly sends a signal back to the MCU confirming the door is locked. If the MCU does not receive this confirmation, it may attempt to lock the door again, resulting in the clicking sound. Voltage travels through a wiring harness to the door lock.

Symptoms:

US homeowners report the Whirlpool washer door lock is clicking repeatedly, usually three times, but the washing cycle doesn't start, and no error code is displayed on the control panel.

Possible Causes:

Faulty door lock assembly
Obstruction preventing door latch engagement
Wiring harness issue between MCU and door lock
Damaged door strike
Weak or failing door lock motor
Issue with the MCU (Main Control Unit)

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Visually inspect the door lock assembly for any visible damage or obstructions. Remove any debris.
3

Using a multimeter, check the wiring harness connector at the door lock for continuity. Refer to the wiring diagram.
4

Test the voltage to the door lock motor during the lock cycle. You should see approximately 120V AC momentarily.
5

If voltage is present but the lock still clicks, replace the door lock assembly.
6

If no voltage is present, inspect the wiring harness back to the MCU. Look for loose connections or damaged wires.
7

As a last resort, if all other components check out, consider replacing the MCU.

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. High voltage is present in this appliance; exercise caution.

Prevention:

Regularly inspect and clean the door seal. Avoid slamming the door shut. Check for loose articles of clothing that could obstruct the door lock mechanism. Periodically check the wiring harness for wear and tear.

Expert Tip:

Try running the washer through its diagnostic test cycle. This can often reveal hidden error codes not displayed during normal operation. Refer to the service manual for the specific button sequence to enter diagnostic mode; it typically involves pressing a combination of buttons like 'Start,' 'Cancel,' or 'Power'.

Frequently Asked Questions

•What is the resistance reading I should expect across the door lock motor?

Typically, a healthy door lock motor will have a resistance reading between 20 and 50 ohms. Refer to the service manual for the exact specification for your model.

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

The wiring diagram is usually located inside the control panel housing or inside the back panel of the washer. You can also search online using your model number and 'wiring diagram'.

•How do I access the door lock assembly for replacement?

Accessing the door lock assembly usually involves removing the top panel of the washer. This typically requires removing screws located at the back of the unit. Once the top panel is removed, you should have access to the door lock assembly.
