Clean machine
With frequent washing at low temperatures there is a danger of a build-up of
bacteria in the washing machine.
Cleaning the washing machine will significantly reduce bacteria, mould, and
biofilm and prevent the build-up of unpleasant odours.
Note – Optimum results can be achieved by using the Miele IntenseClean
machine cleaner. Alternatively, a universal powder detergent can
be used.
– Dispense the washing machine cleaner or universal detergent
directly in the drum.
– Do not load any laundry. The drum must be empty for this
machine maintenance wash.
