Most Common LG Washing Machine Mechanical Issues and How to Fix Them
Owning an LG washing machine usually means reliable performance, but even well-built appliances can develop mechanical problems over time. Wear, moisture, and constant vibration can cause parts to fail, often leading to loud noises, shaking, or the machine stopping mid-cycle.
Understanding common LG washing machine mechanical issues helps you catch problems early and avoid costly damage. Below, we break down the most frequent mechanical failures, what causes them, and how they are typically fixed.
Loud Roaring Noise Caused by Drum Bearing Failure
A loud roaring or rumbling sound during the spin cycle is one of the most common LG washer mechanical problems. Many homeowners describe it as a “jet engine” noise coming from the laundry room.
This usually happens when water leaks past the tub seal and damages the drum bearings. Over time, the bearings wear out and lose their ability to support the drum properly.
How to check:
Rotate the drum by hand
If it feels loose, rough, or wobbly, the bearings are likely failing
Replacing drum bearings is a complex LG washing machine repair. Addressing it early can prevent damage to the outer tub and drum assembly.
According to experienced appliance technicians, ignoring worn bearings often leads to spider arm failure, which can destroy the entire drum system.
Excessive Shaking and Vibration During Spin Cycle
If your LG washer shakes violently or “walks” across the floor, the problem is usually related to the suspension system.
Common causes include:
Worn shock absorbers: These control drum movement during high-speed spins
Unlevel machine: Uneven flooring or misadjusted feet can cause instability
The fix:
Use a level to ensure all four feet are firmly on the ground
If the washer is level but still shaking, the internal shock absorbers may need replacement
This is one of the most frequent LG washing machine complaints and should not be ignored, as continued vibration can damage internal components.
Drainage Problems and the OE Error Code
When an LG washing machine fails to drain, the issue is often mechanical rather than electronic. The most common causes are a clogged drain filter or a failed drain pump.
Start with these steps:
Check and clean the drain filter located at the bottom front of the washer
Listen for unusual sounds from the pump
If the pump makes a grinding or humming noise but does not move water, the pump motor has likely failed. Replacing the drain pump is a standard LG washer repair and usually restores proper drainage.
Resetting LG Smart Diagnosis for Basic Troubleshooting
Some LG washers include a Smart Diagnosis feature that stores error data. Resetting it can help clear minor system glitches before calling for service.
How to reset:
Power off the washer
Unplug it from the outlet
Press and hold the Start/Pause button for 5 seconds
Plug the machine back in and run a test cycle
This reset allows the system to recalibrate and may resolve minor operational issues.

Essential Washing Machine Maintenance Tips
Preventing LG washing machine mechanical issues starts with regular maintenance:
Clean the gasket: Wipe the rubber seal after each wash to prevent moisture damage
Balance loads properly: Overloading puts stress on bearings and suspension parts
Use HE detergent: Excess suds can strain sensors and mechanical components
These simple habits can significantly extend the life of your washer.
