LG Washing Machine: drum bearing failure, mold issues, leaking
What is this symptom?
Experiencing issues with your LG washing machine? If you're hearing grinding noises, feeling excessive vibration, or noticing mold and leaks, it may be due to drum bearing failure or a compromised door gasket. These problems can lead to water leaks and musty odors during wash cycles. Don't let these issues persist—address them promptly to avoid further damage.
Important Tips for LG Models
- LG washers can include mold-prevention features (e.g., Door-Stop on some models) but still require regular cleaning
Possible Causes
Worn or failed drum bearings allowing water ingress
How to Identify: Loud rumbling/grinding noises during spin cycle, excessive vibration, water leaking from drum area, drum feels loose/wobbly

Loose/cracked hoses or improper hose connections
How to Identify: Water pooling under or behind washer, visible hose damage or loose clamps, leaks during fill or drain stages

Damaged or worn door seal/gasket causing water leakage
How to Identify: Visible tears/cracks in gasket, leaks during wash/spin near door edge, mold or residue buildup
Part: Door seal (gasket)
Clogged or faulty drain pump/filter leading to overflow leaks
How to Identify: Water leaks during drain stage, OE error codes, slow/failed draining
Part: Drain pump/filter
