Possible Causes

Frequent low-temperature washes, Residual detergent and fabric softener in seal and drum, Clogged drain paths, Poor ventilation after use

How to Fix / Troubleshooting

Safety first: Use gloves and ensure good ventilation when using cleaning agents.

  • Run a maintenance wash: Run an empty 60–90°C cotton cycle with a washing machine cleaner or 1–2 cups of white vinegar (check Teka manual for compatibility).
  • Clean door seal: Wipe the gasket folds with a cloth soaked in mild detergent or diluted bleach. Remove visible mold and residue.
  • Clean detergent drawer: Remove and scrub the drawer and housing to eliminate slime and mold.
  • Leave door open: After each use, leave the door and detergent drawer slightly open to allow drying.

Warning: Do not mix bleach with vinegar or other cleaners; dangerous fumes can form.
