If your washing machine is making a grinding noise, it can be concerning. However, 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 tips to repair it. Additionally, we will address commonly asked questions about this issue.

Understanding the Cause: Why is Your LG Washing Machine Making a Grinding Noise?

In some instances, the grinding noise emanating from your washing machine may not necessarily signify a problem with the appliance itself, and it’s crucial to explore this possibility before assuming a malfunction.

However, there are several potential reasons for grinding noises during different cycles.

Issues such as slipping agitator dogs, strain or damage to the drive pulley, U-joint failure connecting the agitator to the transmission, glitches in the stator assembly responsible for drum spinning, defects in the motor control board, worn-out tub bearings, and a deteriorated motor coupling can all contribute to the unwanted sounds.

In the forthcoming sections, we will delve into each of these reasons, providing insights into diagnosis and repair procedures to help address the grinding noise in your washing machine comprehensively. 

How to Repair Grinding Noises During Washing Machine Agitation?

Tip #1: A foreign object is stuck between the drum and tub

If you’re experiencing a grinding noise in your LG washer due to a foreign object stuck between the drum and tub, take these steps for a DIY solution.

Start by ensuring safety, disconnect the power, and access the drum, either through the front or rear panel.

Carefully remove the foreign object, checking for any damage to the drum or surrounding components.

Rotate the drum if needed for better access. After clearing the obstruction, inspect for damage and reassemble the washer.

Plug it in, run a test cycle, and ensure the washer operates smoothly. 

Tip #2: Check the Motor and the Pump

The motor and pump play essential roles in the proper functioning of a washing machine.

To inspect the motor and pump in your LG washer, begin by prioritizing safety and disconnecting power.

Depending on your washer model, access the motor and pump by removing the front or rear panel, referring to the user manual for guidance.

Use a multimeter to check the motor for resistance, identifying any signs of burnout or faults that may require replacement.

When the LG washer makes noise and won’t drain, it will display an OE error code, which means it has an issue with the drain pump.

Please check the filter first and see if it is clean. Additionally, manually rotate the pump impeller to ensure it moves freely, addressing any obstructions or resistance.

If you see some damage which you can not replace yourself, always prioritize safety, and if uncertainties arise, or you need expert assistance, consider contacting TechVill for professional guidance and repair services. 

Tip #3: Agitator Dogs are Slipping

The agitator dogs are small plastic or metal parts inside the agitator that engage with the agitator cam. If these dogs become worn or damaged, they can cause a grinding noise during the washing machine’s agitation cycle.

To address the issue of slipping agitator dogs causing a grinding noise in your washing machine, follow these steps to fix it yourself.

First, access the agitator by opening the washer lid and, depending on your model, removing any covering like a fabric softener dispenser or cap.

Next, remove the agitator by loosening and removing the bolt or nut securing it to the drive shaft, using the appropriate tool. Lift the agitator out of the washing machine and inspect the agitator dogs for signs of wear, breakage, or damage.

If any issues are identified, consider replacing the agitator dogs to resolve the problem. 

Tip #4: Addressing Drive Pulley and U-Joint Issues

If you notice a noise sound in your washing machine, it might be due to a worn or damaged drive pulley or a U-joint failure.

Begin by disconnecting the power and, depending on your washer model, removing the front or rear panel to access these components.

Inspect the drive pulley and U-joint for visible signs of wear, damage, or strain, and check for loose components or foreign objects.

If any parts appear loose, use appropriate tools to tighten them. After these steps, reassemble the washer, plug it in, and run a test cycle to check for resolved grinding noises.

If worn or damaged parts are identified, consider consulting professional technicians from TechVill for a comprehensive assessment and any necessary repairs or replacements.
