Automatic descaling Risk of damage from splashes from the descaling solution. Sensitive surfaces and/or natural floors can suffer damage. Wipe up any spillages of descaling solution. 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 program for descaling the machine. For automatic descaling, a Miele Descaling Cartridge needs to be installed 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 daily descaling to start using the Descaling 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 pipework 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 an environment that is consistently free of limescale, the coffee machine needs to be manually descaled from time to time. The intervals are determined by your usage behavior 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. What you need to note before and during automatic descaling: The coffee machine must be ready to use and the following conditions must be met: - A descaling cartridge which is ready to use is installed. - The coffee machine is connected to the power supply. The coffee machine must not be disconnected from the power supply during automatic descaling. - The drip tray, brew unit, and main dispenser are inserted. - The water container is inserted and is filled with water at least up to the  descaling symbol. - Carry out the instructions which appear in the display before switching off, e.g., Empty the drip tray. - The milk pipe is inserted into the aperture in the drip tray. - The coffee machine is switched off. 86

Automatic descaling
86
Risk of damage from splashes from
the descaling solution.
Sensitive surfaces and/or natural
floors can suffer damage.
Wipe up any spillages of descaling
solution.
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 program for descaling the
machine. For automatic descaling, a
Miele Descaling Cartridge needs to be
installed 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 daily descaling
to start using the
Descaling 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 pipework 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 an environment that
is consistently free of limescale, the
coffee machine needs to be manually
descaled from time to time. The
intervals are determined by your
usage behavior 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.
What you need to note before
and during automatic
descaling:
The coffee machine must be ready to
use and the following conditions must
be met:
-
A descaling cartridge which is ready
to use is installed.
-
The coffee machine is connected to
the power supply. The coffee
