LG Top Load Washer Making Grinding Noise

Quick answer

A grinding noise in your LG top load washer is often caused by a worn-out motor coupling or a damaged transmission. Turn off the washer, unplug it, and check for foreign objects in the drum. If the noise persists, replace the motor coupling or consult a professional.

Confirm the symptom

• Grinding or rumbling noise during the spin cycle
• Noise gets louder when the washer is empty
• Washer vibrates excessively during operation
• You hear the noise even when the washer is not agitating

Tools and prep

• Screwdriver (Phillips and flathead)
• Socket set and wrenches
• Work gloves
• Flashlight
• Plastic putty knife
• LG washer user manual
• Turn off the washer and unplug it from the power source
• Close the water supply valves

Step-by-step troubleshooting

1. Inspect the Drum for Foreign Objects
   Do: Visually check the inside of the drum for any objects like coins, buttons, or debris that might be caught in the drum or agitator.
   Observe: Foreign objects caught in the drum or agitator.
   Means: The grinding noise is likely caused by an object interfering with the drum's rotation.
   Next: Remove the object and test the washer again.
2. Check the Agitator
   Do: Remove the agitator cap and inspect the agitator for damage or wear. Look for loose or broken parts.
   Observe: Cracks, wear, or loose components in the agitator.
   Means: A damaged agitator can cause a grinding noise during operation.
   Next: Replace the agitator if damaged.
3. Examine the Motor Coupling
   Do: Locate the motor coupling (usually at the back of the washer) and check for wear or damage. Use a screwdriver or socket set to access it.
   Observe: Worn or broken motor coupling.
   Means: A worn motor coupling is a common cause of grinding noises.
   Next: Replace the motor coupling.
4. Inspect the Transmission
   Do: Remove the back panel and visually inspect the transmission for signs of wear or damage. Check if the gears are intact and properly aligned.
   Observe: Worn gears or damaged transmission.
   Means: A faulty transmission can cause grinding and rumbling noises.
   Next: Replace the transmission if damaged.
5. Check the Drum Bearings
   Do: Lift the drum slightly and rotate it to check for rough movement or grinding sounds from the bearings.
   Observe: Grinding sound or rough rotation from the drum bearings.
   Means: Worn drum bearings can cause a grinding noise during operation.
   Next: Replace the drum bearings.
6. Test the Washer
   Do: Plug the washer back in and run a test cycle to see if the noise persists.
   Observe: Grinding noise returns or is resolved.
   Means: If the noise is gone, the issue was likely a foreign object or a replaceable part.
   Next: If the noise continues, consider calling a professional technician.

Common causes

Parts matching

If you need to replace parts, match these common issues with the right components:

• Motor Coupling: Replaces the worn coupling connecting the motor and transmission
• Transmission: Replaces a damaged or worn transmission
• Drum Bearings: Replaces worn bearings allowing the drum to rotate smoothly
• Agitator: Replaces a cracked or broken agitator

Always refer to your LG washer's model number when ordering replacement parts to ensure compatibility.
