LG Washing Machine: mold growth
What is this symptom?
Experiencing mold growth in your LG washing machine? This issue manifests as dark patches in the drum, rubber gasket, or detergent dispenser, often accompanied by a musty odor. Mold thrives in damp environments, making it essential to address this problem to ensure clean laundry and a healthy appliance.
Important Tips for LG Models
- LG-specific troubleshooting indicates infrequent hot washes, closed doors, residual detergent and clogged drain/gasket areas contribute to mold growth.
- Official LG support acknowledges potential risk of mildew build-up in front load washers.
Possible Causes
Residual moisture in drum and gasket after wash cycles
How to Identify: Visible dampness, black or brown mold spots around rubber gasket or drum edges and a musty smell.
Part: Drum interior, door gasket
Detergent and fabric softener residue buildup
How to Identify: Sticky residue or film inside detergent drawer or drum promoting mold food source.
Part: Detergent dispenser, drum surfaces
Infrequent hot or cleaning cycles
How to Identify: Lack of periodic hot water wash leading to accumulation of biofilm and visible growth.

Clogged or poorly draining areas
How to Identify: Water pooling after drain cycle, mold in hard-to-reach drain or gasket areas.
Part: Drain area, gasket crevices
