1. Check if the drain hose is correctly connected to the siphon, or if your waste installation is equipped with a siphon.

2. Dispense the correct amount of detergent, avoid using only cold cycles and run hot cycles/wash regularly.

3. Dispense the correct amount of detergent and conditioner according to the manufacturer’s instructions.

4. Always leave the door ajar/slightly open after every wash and, if possible, open the dispenser drawer slightly at the same time so that the machine can dry out between washes. Assure that the appliance is installed in the room with good ventilation 

5. Check whether the washing machine heats up by starting a very hot wash. 

The door should remain warm during the cycle (can be checked after about half to one hour).

6. Regularly carry out a 90°C service wash using a washing machine cleaner to avoid unpleasant smells and marks around the door. 

For detailed procedures refer to the user manual supplied with your appliance. Download the user manual

We recommend specialized cleaning detergents available on our Webshop.

7. Clean the detergent dispenser:

  • Remove any spillage or residue in each compartment by rinsing it under hot running tap water. 
  • Remove the dispenser and use a suitable brush (clean it with an old toothbrush) to remove any dirt and dried soap powder/liquid from each section

8. Clean the pump and fluff filter, including the pump blade (if the pump blade is visible, rotate it with a pencil and refit the filter). For detailed procedures refer to the user manual supplied with your appliance.

  • Turn off the appliance.
  • Open the door to the fluff filter and place the drip tray underneath.
  • Empty any water out of the machine by opening the drain hose next to the filter.
  • Remove the filter by turning it anti-clockwise (several times firmly by hand).
  • Clean the filter and pump housing under running water and refit the filter.
  • Close the drain hose and put it back in its original place.
  • Close the flap to the fluff filter.

9. Clean the washing machine’s seal:

Rubber seals on washing machines often develop dark or black mould spots.

  • You can remove the mould using sodium carbonate crystals, thick bleach or dishwasher cleaner, which helps to dissolve any stubborn mould and soap powder residue.
  • Be sure to wear rubber gloves and protective goggles during this cleaning operation.

10. Cleaning the washing machine externally:

  • Use a cloth soaked in a mild universal detergent or washing-up liquid, because washing machines are often manufactured from baked-on enamel. 
  • Carefully wipe down the outside of the washing machine.
  • You may find that fluff and splashes of washing powder have formed thick, greasy stains on the washing machine.
  • A little warm water and a cloth are usually enough to clean up the area.
  • Try cleaning in corners and edges using a cotton bud.
