My washing machine manufacturer (Miele) state that I cannot use softened water with their machine. Is this correct?

Some washing machine manufacturers are extra cautious with regard to softened water. We know that Miele in particular write about this in their guidance.  

The issue is not actually because of the softened water itself – it’s because softened water needs less detergent, so you need to alter your dosing habits.   

When youre using softened water, you should cut down the amount of detergent you use by 75%. Fabric conditioner isn’t needed either. This will save you money and eliminate any chance of overdosing on detergent  

In addition to making savings on detergents and conditioners, you’ll also notice other benefits to washing with softened water such as cleaner and brighter clothes and your washing machine will be protected from scale and scum.

Guidance from Miele 

Recently we advised one of our customers on this issue, as they have a Miele machine. They received the following response from Miele: 

“Many of our customers make use of domestic water softeners, which gives them the benefit of a softened water supply. We can confirm that whilst there are issues to take into consideration when connecting any washing machine to a water softener, as long as these are adhered to, this will not affect the performance or durability of the appliance and will not invalidate your extended guarantees, providing any future faults are not caused by the water softener. If using Miele TwinDos detergent dosing, you need to follow the commissioning section in the instruction manual and set the washing machine for the softest water level available. Normally Ultra Phase 1 Hardness level 1. This may be different for specific models, please check your actual manual for model specific settings.”  

Our water softeners help you around the home in so many ways. Softened water can prevent limescale build-up in taps, pipes and appliances. Many people think it tastes better than hard water, and it’s much softer on skin. Contact us
