How to descale the washing machine? 4 tips on how to descale a washing machine

As your washing machine uses hot water, this can cause a buildup of limescale. Too much limescale can affect the performance of your washing machine. It can collect on your clothes, cause your machine to use more energy to heat up, and shorten its lifespan.

Descaling your washing machine can keep your machine working well and your clothes clean. In this article we share a number of tips for descaling your washing machine and keeping it scale-free.

The cause of limescale in the washing machine


Limescale is often formed in areas where water has been heated. The scale particles in the water bond to the surfaces where heat and water come together.

If you live in a region that uses hard water, like Southern areas in the UK, limescale builds up more quickly. Hard water has a higher calcium and magnesium content, which means your washing machine is exposed to more scale.

Limescale builds up slowly, so you don’t need to descale your washing machine so often. However, it is still important to keep on top of descaling your washing machine.
