Descaling - Miele Built-in coffee machine Operating And Installation Instructions

Descaling

Limescale builds up in the coffee
machine through use. How often the
machine needs to be descaled will
depend on the water hardness level in
your area. It should be descaled
regularly to ensure that it functions
correctly.
The machine will guide you through the
descaling process. Various messages
will appear in the display, e.g. you will
be prompted to empty the drip tray or
fill the water container.
Descaling must be carried out. The
process takes approx. 20 minutes.
During the descaling process, water
containing descaling agent will run out
of the central spout and the hot water
spout. This is followed by an activation
period before a little more water
containing descaling agent is
dispensed.
The coffee machine will remind you
when descaling needs to be carried
out. The following message will appear
in the display "No. of uses until
appliance needs descaling: 50". The
remaining number of drinks that can be
made before descaling will now show in
the display after each drink is made.
^ Touch "OK" to confirm this message.
When 0 is reached, the coffee machine
will lock out. "Descale the appliance"
will appear in the display.
You can switch off the coffee machine if
you do not want to descale it at this
time. However, you will be not be able
to make any more drinks until descaling
has been carried out.

appears in the display, proceed as
described below.
Preparing the descaling solution
We recommend using Miele descaling
tablets. These have been specially
developed for use with Miele
appliances to optimise the descaling
process.
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.
