Whirlpool Top Load Washer: Metallic Clicking Sound... | appliancefaults.com

Technical Background:

The Whirlpool top load washer uses a motor controlled by the MCU (Main Control Unit). The motor rotates the drive pulley which in turn drives either the agitator (for washing) or the spin basket (for spinning). Agitation relies on the agitator dogs to create the back-and-forth motion. Voltage paths from the MCU activate different motor windings for washing and spinning.

Symptoms:

The homeowner reports a noticeable metallic clicking sound coming from the washing machine during the agitation cycle. The clicking is present regardless of load size or wash cycle selected.

Possible Causes:

Worn or damaged agitator dogs
Loose or broken drive pulley
Stripped or cracked agitator assembly
Foreign object trapped in the agitator or tub
Failing transmission or gear case

Solution:

1

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

Remove the agitator cap (usually pulls straight up or requires a flathead screwdriver).
3

Inspect the agitator dogs for wear or damage. Replace if necessary. These are usually inexpensive plastic parts.
4

Check the agitator assembly for cracks or stripping where it connects to the drive shaft. Replace if damaged.
5

Remove the front panel (usually screws at the bottom) or the top panel (often clips at the rear) to access the drive pulley. A 1/4-inch nut driver or 5/16-inch socket is often useful.
6

Inspect the drive pulley for looseness or damage. Tighten the pulley nut with a socket wrench or replace the pulley if necessary. Ensure belt tension.
7

If the clicking persists, suspect transmission issues. A transmission replacement is often best left to a licensed technician due to complexity and cost.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Follow Lock Out/Tag Out (LOTO) procedures to ensure the unit is de-energized. Be aware that some components may store energy even after the unit is unplugged. High voltage circuits are present – exercise caution.

Prevention:

Avoid overloading the washing machine. Regularly check and clean the lint filter to prevent clogs that can strain the motor and transmission. Use the appropriate amount of detergent.

Expert Tip:

Many Whirlpool washers have a diagnostic mode. Simultaneously press and hold the START/PAUSE and CYCLE SIGNAL buttons for 3 seconds to enter diagnostic mode. This can reveal error codes related to the motor or transmission.

Frequently Asked Questions

•How do I know if the transmission is failing?

Signs of a failing transmission include loud grinding noises, difficulty agitating or spinning, and oil leaks. If you suspect a failing transmission, it's often more cost-effective to replace the entire washer.

•What kind of grease should I use on the agitator dogs?

A small amount of waterproof, food-grade silicone grease can be applied to the agitator dogs to improve their movement and reduce wear.

•Where can I find replacement parts for my Whirlpool washer?

Replacement parts can be found at most appliance parts retailers, both online and in local stores. Be sure to have your model number handy to ensure you get the correct parts.
