Important Tips for Beko Models

  • Beko recommends regular cleaning of door seal with cloth and baking soda/vinegar solutions and to use self‑cleaning functions (e.g., DrumClean+).

Possible Causes

Moisture trapped in door seal folds

How to Identify: Water remains in the folds of the rubber gasket after cycles; visible dampness and mould growth in crevices.

Part: Rubber door seal/gasket

Detergent and fabric softener residue buildup

How to Identify: Sticky or soapy residue visible on the seal; described black sludge or film.

Part: Seal surface and gasket folds

Frequent low-temperature washes

How to Identify: Mostly cool wash cycles used allowing bacterial/mold spores to survive.

Part: Drum and seal area

Poor ventilation after wash

How to Identify: Machine door remains shut after cycles; high humidity inside air space.

Part: Overall interior & door area

Worn or damaged rubber seal (traps moisture more readily)

How to Identify: Cracks or tears in gasket; frequent persistent mould despite cleaning.

Part: Rubber door gasket
