How to Fix / Troubleshooting
Safety First: Unplug the washer before cleaning internal rubber parts. Avoid mixing cleaning chemicals.
Step-by-step cleaning:
- Clean door bellow: Wipe the gasket folds with a cloth soaked in a 1:1 solution of white vinegar and water or a manufacturer-approved cleaner. Remove all visible residue.
- Run cleaning cycle: Use the washer's "Clean Washer" cycle if available, with a washer cleaner tablet or 1 cup of white vinegar (no clothes).
- Clean dispenser: Remove and wash the detergent drawer and housing to remove buildup.
- Improve ventilation: After each use, leave the door and dispenser drawer slightly open to allow drying.
When to replace: If the door bellow is heavily stained or retains odor even after cleaning, consider replacing it. Also address any drain issues that leave standing water.
