Depending on how you use your
machine and the water hardness level
in your area, occasionally you will
need to descale your machine
manually in addition to automatic
descaling.
If a descaling cartridge is not fitted, an
empty cartridge is fitted or an expired
cartridge is fitted, the machine needs to
be descaled regularly using the
the machine maintenance programme.
The appliance 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.
You need 1 descaling tablet for the
descaling process. The process takes
approx. 12 minutes.
The coffee machine prompts you when
it needs to be descaled.
until the machine must be descaled:

Preparing the descaling solution
For optimum descaling results, we
recommend using the Miele descaling
tablets provided.
The descaling tablets have been
specially developed for Miele coffee
machines.
Other descaling agents, which
contain other acids besides citric
acid and/or other undesirable
substances, such as chlorides, may
cause damage to the appliance.
Moreover, the descaling result
required cannot be guaranteed if the
descaling solution was not of the
appropriate concentration.
Miele descaling tablets are available to
order via the Miele webshop or directly
from Miele (see the end of this booklet
for contact details).
