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

Technical Background:

The washer's MCU (Main Control Unit) controls the motor speed and direction via relays. The motor drives the transmission, which in turn rotates the agitator or spin basket. A metallic grinding noise often indicates mechanical failure within the drive system. Voltage to the motor should be 120V AC during operation.

Symptoms:

The US homeowner reports a loud metallic grinding noise during the wash or spin cycle of their GE top load washer with a Dual Action Agitator. The noise is particularly noticeable when the agitator is engaged or during high-speed spinning.

Possible Causes:

Worn or damaged agitator dogs (cams).
Stripped or cracked drive pulley.
Failed or failing transmission.
Foreign object lodged between the spin basket and outer tub.
Worn or damaged tub seal.

Solution:

1

Unplug the washer from the 120V AC power outlet. Always Lock-Out/Tag-Out the breaker.
2

Remove the agitator. Use a 7/16-inch socket to remove any retaining bolt. Inspect the agitator dogs (cams) for wear or damage. Replace if necessary.
3

Check the drive pulley underneath the washer. Access it by removing the cabinet (usually two screws at the rear). Inspect the pulley for cracks or stripping.
4

Manually rotate the drive pulley. Listen for any grinding noises coming from the transmission. If grinding is present, the transmission likely needs replacement.
5

Inspect between the spin basket and outer tub. You may need to remove the agitator and inner basket to visually inspect and remove any obstructions. Use a shop vacuum to help.
6

Check the tub seal for leaks or damage. If the seal is leaking, water can damage the transmission bearings, leading to grinding noises. Check for rust or water stains around the seal.
7

If the transmission is suspected, consider whether the repair cost justifies the washer's age.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Capacitors can store a lethal electrical charge even after the appliance is unplugged. Lock-Out/Tag-Out the breaker to prevent accidental re-energizing of the circuit. Wear appropriate safety gear, including gloves and eye protection.

Prevention:

Avoid overloading the washer. Regularly check and clean the lint filter. Periodically inspect the agitator dogs (cams) for wear and replace them as needed. Use appropriate detergent amounts.

Expert Tip:

Many GE washers have a service mode. Typically, pressing and holding the start and cycle select buttons for 3 seconds enters service mode. This allows you to run diagnostic tests on the motor and other components.

Frequently Asked Questions

•How do I remove the agitator?

Typically, there is a bolt or cap at the top of the agitator. Remove the bolt using a 7/16-inch socket. Some agitators may require a special tool to release them.

•How do I know if the transmission is bad?

A bad transmission will often make grinding or clunking noises during both agitation and spin cycles. Also, the agitator or spin basket may not rotate smoothly or at all.
