Possible Causes
Detergent residue in door boot, stagnant water in drain sump, infrequent hot washes, clogged drain filter
How to Fix / Troubleshooting
Safety first: Unplug the washer before cleaning internal filters. Use gloves when handling moldy parts.
Step-by-step cleaning:
- 1. Clean door boot: Wipe the rubber gasket with a cloth soaked in a 1:1 mixture of white vinegar and water. Pull back folds to remove trapped debris.
- 2. Clean dispenser drawer: Remove the drawer and soak in hot soapy water. Scrub away mold and residue.
- 3. Clean drain filter: Open the pump clean-out and remove lint and debris. Rinse the filter thoroughly.
- 4. Run a tub clean cycle: Run the hottest, longest cycle with no clothes, using a washer cleaner or 1–2 cups of white vinegar.
- 5. Leave door open: After each use, leave the door and dispenser drawer slightly open to allow drying.
When to call a technician: If odor persists and you suspect hidden leaks or standing water, a professional inspection may be needed.
