If your washing machine is making a grinding noise, it can be concerning. Understanding the possible causes and knowing how to fix the issue can help you resolve the problem.

In this article, we will discuss the various reasons why your washing machine may be making a grinding noise and provide helpful repair tips.

Understanding the Cause: Why Is Your LG Washer Making a Grinding Noise?

In some cases, a grinding noise does not necessarily mean a major malfunction. However, several mechanical issues can cause grinding sounds during different cycles.

Common causes include slipping agitator dogs, a worn drive pulley, U-joint failure, stator assembly issues, motor control board defects, worn tub bearings, or a damaged motor coupling.

Below, we break down the most frequent causes and how to address them.

How to Repair Grinding Noises During Washer Agitation

Tip #1: A Foreign Object Is Stuck Between the Drum and Tub

A foreign object trapped between the drum and tub can create grinding noises.

Disconnect the power before inspecting the washer. Access the drum through the appropriate panel and carefully remove any debris. Check for visible damage, reassemble the unit, and run a test cycle.

Tip #2: Check the Motor and the Pump

The motor and drain pump are critical components.

Disconnect power and access the motor and pump by removing the front or rear panel. Use a multimeter to test motor resistance and inspect for signs of damage.

If your LG washer displays an OE error code and makes noise while failing to drain, this typically indicates a drain pump issue. Check and clean the pump filter first. Manually rotate the pump impeller to ensure it moves freely.

If damage is found and you are unable to replace the component safely, consider professional assistance.

Tip #3: Agitator Dogs Are Slipping

Agitator dogs are small components that engage the agitator mechanism. When worn, they can cause grinding during agitation.

Access the agitator by removing the cap or dispenser. Unscrew the securing bolt, lift the agitator, and inspect the dogs for wear or breakage. Replace them if necessary.

Tip #4: Drive Pulley and U-Joint Issues

A worn drive pulley or failed U-joint can also create grinding sounds.

Disconnect power and access the components. Inspect for visible wear, strain, or loose parts. Tighten any loose components. If damage is detected, replacement may be required.

If grinding noises persist after troubleshooting, the issue may require professional diagnosis.
