Descaling a washing machine

At Bosch, we are well aware of the negative effects of limescale on washing machines, especially in hard water areas. The worst of these effects is a build up of limescale on the heating element, which can result in this component becoming less effective at heating up the water. Even worse, it may need to be replaced entirely by a Bosch engineer.

It's for this reason that we highly recommend descaling a washing machine every three to six months with our tested and approved washing machine descaler. This helps protect against the build up of limescale deposits and prolongs the life of your appliance. Watch the video below to learn how to descale a washing machine the correct way, every time.

Step by step guide

  • Ensure the washing machine is empty and all the laundry is removed.
  • Open the detergent drawer and pour the entire contents of the Quick Descaler into the drum.
  • Close the detergent drawer, select a 60°C programme without pre-wash and start the appliance. Let the programme run until the end.
  • Run the same programme again until completion, this time without the descaling powder. This will help thoroughly clean through the appliance and remove any residues.
