Symptoms
- Sour or musty smell from the drum
- Odor transfers to freshly washed clothes
- Black or pink residue in the door gasket fold
- Smell stronger when the door has been closed for a while
Likely causes
- CommonMoisture trapped in the door gasket foldFront-load gaskets have a fold that holds water and lint, creating a perfect spot for mold.
- CommonDetergent or fabric softener residue buildupUsing too much detergent, especially non-HE detergent in an HE machine, leaves residue that grows mold.
- CommonDoor left closed after washingA sealed, damp drum without airflow encourages mold and mildew growth between uses.
- PossibleClogged or dirty detergent/softener dispenser drawerResidue builds up in the drawer tray and its housing over time.
- PossibleBuildup in the drain pump filter or hoseTrapped water and lint in these areas can also produce odor.
What to do
- Wipe out the door gasket fold thoroughly with a cloth and a mix of water and white vinegar or a bit of bleach diluted per label instructions.
- Remove the detergent drawer if possible and wash it with warm soapy water, scrubbing the housing behind it with an old toothbrush.
- Run an empty hot cycle with a washing machine cleaner or 2 cups of white vinegar to break down residue in the drum.
- Leave the door and detergent drawer open between uses to let the interior air out and dry.
- Switch to the recommended amount of HE detergent if you've been using too much or the wrong type.
- Clean the drain pump filter, since trapped water there can also cause persistent odor.
