The laundry or washer-dryer smells unpleasant.
Run a 95 °C wash programme and add some machine cleaner.
Make sure that you wash at a temperature of at least 75 °C at least once a month.
Do not use colour detergent or liquid detergent all the time. Alternatively, add bleaching agent regularly.
Try a different detergent.
Check the detergent amount dispensed. The dispensing quantity will depend on the degree of soiling of the laundry, load size and water hardness.
Use dispensing aids (e.g. dispenser balls) if these are supplied with the detergent, particularly when using liquid detergent.
Check the basic dispensing quantity.
