LG Washing Machine: off-gassing odor
What is this symptom?
Experiencing an off-gassing odor from your LG washing machine? This unpleasant smell, often resembling mildew, chemicals, or rubber, can occur during or after cycles. Common in front-load and washer-dryer models, the odor may persist even when idle or after opening the door. The primary culprits are mildew and bacterial growth due to moisture and residue buildup, as well as excess detergent use.
Possible Causes
Mildew and bacterial growth from moisture and residue buildup
How to Identify: Musty, damp cloth‑like odor especially after idle periods; visual mold/tar buildup around door gasket/rubber seal or inside drum; repeated occurrence after wash cycles.
Part: Drum/tub interior, door gasket, detergent drawer
Excess detergent or fabric softener residue
How to Identify: Smell persists despite typical cleaning; visible sticky residue or suds film; occurs when too much detergent or high‑foam detergent is used.
Part: Detergent dispenser, drum interior
