GE Top Load Washer: Metallic Grinding Noise... | appliancefaults.com

Technical Background:

The GE top load washer uses a Motor Control Unit (MCU) to manage the motor speed and direction. The MCU receives signals from the water level sensor, lid switch, and other components. It then controls the motor via relays or electronic switches, using 120V AC power. A metallic grinding noise suggests mechanical failure in the drivetrain.

Symptoms:

The homeowner reports a loud metallic grinding noise occurring during the wash or spin cycle of their GE top load washer, particularly noticeable when the Dual Action Agitator is engaged.

Possible Causes:

Worn or damaged agitator dogs
Failed transmission or gear case
Worn or damaged drive belt
Foreign object lodged in the tub or agitator
Defective tub bearing
Motor coupler failure

Solution:

1

Unplug the washer from the outlet.
2

Remove the agitator assembly (usually a cap and a bolt or nut). Examine the agitator dogs for wear or breakage. These are small plastic pieces that allow one-way rotation. Replace if damaged.
3

Access the drive belt (usually from the rear of the washer after removing an access panel). Inspect the belt for cracks, fraying, or looseness. Replace if necessary. Use a 5/16-inch nut driver for panel removal.
4

With the belt removed (or if it's a direct-drive model), manually rotate the inner tub. Listen closely for grinding sounds. A grinding noise during manual rotation strongly suggests a failing tub bearing. Tub bearing replacement requires significant disassembly.
5

Check for any objects lodged between the inner and outer tubs. This might require removing the inner tub. Common culprits are coins, buttons, or small articles of clothing.
6

If the washer utilizes a motor coupler, inspect it for wear or breakage. Replace if damaged. Often, a rubber coupler will degrade over time.
7

If the above steps don't resolve the noise, a failing transmission is likely. Transmission replacement is a major repair, often requiring specialized tools and knowledge.

Safety Warning:

Always unplug the washer from the breaker panel before performing any repairs. Some components carry 120V AC. Use caution and follow proper Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Avoid overloading the washer. Regularly check and clean the lint filter. Do not put excessive weight or pressure on the agitator. Periodically inspect the drive belt for wear.

Expert Tip:

Some GE washers have a service mode that allows you to run diagnostic tests and error codes. To enter service mode, rapidly cycle the power button and observe the LED indicators. Consult the service manual for the specific sequence for your model.
