How to Fix / Troubleshooting

Safety first: Use only cleaning products approved for washers; ensure good ventilation.

Steps:

  • Clean gasket: Wipe the door gasket folds with a mild bleach solution or washer cleaner, removing visible mold and residue.
  • Run tub clean cycle: Use the Café combo's tub clean/sanitize cycle with a washer cleaning tablet.
  • Leave door open: After use, leave the door and dispenser drawer slightly open to allow drying.

When to call a technician: If odor persists and there is visible heavy mold behind the gasket, gasket replacement may be needed.
