Likely causes
- CommonMoisture trapped in the gasket fold without airflowThe design of front-load gaskets holds water in a fold that doesn't dry out if the door is kept closed.
- CommonInfrequent cleaning of the gasket areaMold takes hold when the area isn't wiped down or cleaned regularly.
- PossibleDetergent or fabric softener residue feeding mold growthOrganic residue in the fold provides a food source for mold in addition to moisture.
What to do
- Wear gloves and use a mix of water and white vinegar, or a diluted bleach solution, to scrub the gasket fold thoroughly.
- Pull back the gasket fold gently to clean underneath it where mold often hides.
- Run an empty hot cycle with a washing machine cleaner or 2 cups of white vinegar afterward to clean the rest of the system.
- Dry the gasket fold with a towel after cleaning and after each future wash if possible.
- Leave the door open between uses to let the area air out and prevent regrowth.
- Repeat this cleaning routine monthly, or more often in humid climates, to keep mold from returning.

When to call a pro
This is a routine cleaning task; a technician isn't typically needed unless mold keeps returning despite regular cleaning, in which case a drain or seal issue may be involved.
Safety
Use caution
Never mix bleach and vinegar or ammonia-based cleaners together, since this creates dangerous fumes; use one or the other and ventilate the area.
