How to clean a Bosch washing machine drum

Regular drum cleaning prevents mould, odours, and detergent residue. Clean your Bosch machine monthly or every 4-6 weeks for best results.

Difficulty: Easy
Time: 15 min

Step-by-step

  1. 1

    Empty the washing machine

    Remove any clothes or items from the drum. Check the rubber seal for trapped debris or foreign objects.

    💡 Look inside the rubber gasket as fibres often collect there.

  2. 2

    Run a hot water cycle

    Select 60°C or higher temperature cycle with no wash load. Add 100ml white vinegar or commercial washing machine cleaner to the detergent dispenser.

    💡 Use Bosch-compatible cleaner like Finish or Dr. Beckmann for optimal results.

  3. 3

    Wipe the rubber gasket

    When the cycle finishes, pull back the rubber seal and wipe along the groove with a damp cloth. Remove any black residue or mould spots.

    💡 Work around the entire seal—mould hides in the folds.

  4. 4

    Clean the detergent drawer

    Slide out the drawer fully and rinse under warm water. Use an old toothbrush to scrub the compartments where detergent builds up.

    💡 Detergent residue blocks the dispenser and reduces cleaning performance.

  5. 5

    Dry the drum interior

    Leave the door open for 2-3 hours to air dry completely. This prevents mould growth between cleaning cycles.

    💡 Open the door after each wash to allow moisture to escape naturally.

⚠️ Always disconnect your appliance from mains power before starting any repair. If in doubt, consult a qualified engineer.

FAQs

How often should I clean the drum?
Clean monthly or every 4-6 weeks. If you notice odours or black spots sooner, clean immediately.
What's the best cleaner for Bosch machines?
White vinegar (100ml per cycle), Finish Washing Machine Cleaner, or Dr. Beckmann all work well. Avoid bleach on coloured seals.
Why does my drum smell?
Mould grows in damp conditions and detergent residue. Run a hot 60°C cycle with cleaner and leave the door open to dry between washes.
