Automatic Descaling; Please Note Before And During Automatic Descaling - Miele CM 7550 Operating Instructions Manual

Risk of damage from spilt descaling
solution.
Sensitive surfaces and/or natural
floors can suffer damage.
Wipe up any spillages of descaling
agent.
When handling a cartridge which has
already been filled with water, ensure
that the descaling solution does not
come into contact with sensitive
surfaces.
The coffee machine has an automatic
maintenance programme for descaling
the machine. For automatic descaling, a
Miele descaling cartridge is fitted at the
back of the coffee machine. The coffee
machine will automatically determine
the days when to carry out automatic
descaling based on the usage pattern.
Automatic descaling takes
approx. 4 hours, including the activation
phase.
You can set the time for automatic
descaling to start using the

timer
Water is mixed with the descaling agent
to create a solution for automatic
descaling. This descaling solution is
then pumped through the pipework of
the coffee machine. After the activation
phase the solution is then rinsed out of
the pipwork and the machine can then
be used as normal for making drinks.
During automatic descaling you will
hear pumping and rinsing noises at
frequent intervals even though the
appliance is switched off and the
display is dark.
If you do not make any drinks,
automatic descaling will not be started.
To ensure the longevity of
components and a consistent
environment free of limescale, the
coffee machine needs to be manually
descaled from time to time. The
intervals are determined by your
usage behaviour and the water
hardness level of your area. If you
make a lot of coffees with milk, for
example, you will need to descale the
coffee machine more frequently with
the descaling tablets.
