Unpleasant odour

Washing Machine smells — Unpleasant odour inside

Miele · W1 Washing Machines

What does Unpleasant odour mean?

The Washing Machine emits an unpleasant smell, which can be caused by the buildup of bacteria and residue over time, especially if high-temperature washes are not performed regularly. Leaving the door or detergent drawer closed after a wash can also contribute to this.

Common Causes

  • Bacteria and unpleasant odours have built up because a wash programme above 60 °C has not been run for a long time.
  • The door and the detergent dispenser drawer were left closed after washing, preventing them from drying out.

Repair Steps & Checklist

  1. 1

  2. 2

    After each wash, leave the Washing Machine door slightly ajar to allow the drum to dry and air out.

  3. 3

    Similarly, leave the detergent dispenser drawer slightly open after use to prevent moisture buildup and mould.

  4. 4

    Ensure you are using the correct amount of detergent for your water hardness and load size.
