Whirlpool Washer Clicking Noise During Wash to Spin... | appliancefaults.com

Technical Background:

The Whirlpool washer utilizes a motor control unit (MCU) to manage the various stages of the wash cycle. When the washer transitions from wash to spin, the MCU sends a 120V AC signal to the shift actuator. The shift actuator then engages the appropriate gears to initiate the spin cycle. A malfunction in this process can cause a clicking noise.

Symptoms:

The US homeowner reports a clicking noise occurring when the Whirlpool washer attempts to shift from the wash cycle to the spin cycle.

Possible Causes:

Worn or damaged shift actuator
Defective mode/shift cam
Obstruction in the drain pump
Faulty main control board (MCU)

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Access the shift actuator located near the bottom of the washer. You may need a 1/4-inch nut driver to remove access panels.
3

Visually inspect the shift actuator for physical damage or signs of wear.
4

Use a multimeter to check the voltage to the shift actuator during the shift cycle. You should see approximately 120V AC.
5

If the voltage is present but the actuator is not working, replace the shift actuator.
6

Inspect the mode/shift cam for cracks or damage. Replace if needed.
7

Check the drain pump for any obstructions and remove them.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any repairs. Lock-out/Tag-out (LOTO) procedures are recommended. High voltage components are present, use caution.

Prevention:

Regularly inspect the washing machine hoses for leaks and replace them every 5 years. Avoid overloading the washer to prevent excessive strain on the motor and shift mechanism.

Expert Tip:

Many Whirlpool washers have a diagnostic mode. To enter diagnostic mode, consult the service manual for your specific model. This mode can often provide error codes that pinpoint the exact source of the problem. A common sequence involves pressing certain buttons in a specific order, often involving the start and control knob.

Frequently Asked Questions

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

The diagnostic mode entry sequence varies by model. Consult your washer's service manual or search online using your model number. Common sequences involve pressing the start button followed by specific control knob rotations or button combinations.

•What voltage should I expect to see at the shift actuator during the shift cycle?

You should expect to see approximately 120V AC at the shift actuator connector when the washer is attempting to shift from the wash cycle to the spin cycle. If the voltage is significantly lower, there may be a wiring issue or a problem with the main control board (MCU).

•Where is the shift actuator located in my Whirlpool washer?

The shift actuator is typically located near the bottom of the washer, often accessible from the rear or front panel. It is usually attached to the transmission or gear case. Consult your washer's parts diagram for the exact location based on your model number.
