Make up the descaling solution
We recommend using Miele descaling
tablets for optimum results.
These have been specially developed
for use with Miele coffee machines and
prevent subsequent damage.
Other descaling agents, which
contain other acids besides citric
acid and/or other undesirable
substances, such as chlorides for
example, could damage the coffee
machine. Moreover, the descaling
effect required could not be
guaranteed if the descaling solution
was not of the appropriate
concentration.
Miele descaling tablets are available to
order from your Miele dealer.
You will need one descaling tablet to
descale the machine.
