Automatic descaling

The Miele descaling cartridge

Only use the Miele descaling
cartridge for the automatic descaling
programme.
Please note that the Miele descaling
cartridge has a storage life of approx.
one year after it has been placed in
the machine and filled with water for
the first time. Critical for the one-year
storage life is the date on which the
descaling cartridge was fitted and
filled with water.
Do not use a descaling cartridge
which has already been used in
another Miele coffee machine. Your
coffee machine will have no
information about the fill level of this
cartridge. The descaling effect may
be insufficient and damage your
coffee machine.
Do not fill the descaling cartridge
with other fluids or substances.
The descaling agent comes in the form
of tablets in the descaling cartridge.
The cartridge is filled with water when it
is placed in the machine. The tablets
gradually dissolve over time.
The Miele descaling cartridge will last
for 7 to 12 months of automatic
descaling, depending on how often the
coffee machine is used.
A prompt will appear in the display
shortly before the cartridge is depleted,
reminding you that it needs to be
replaced. Confirm the message with
OK. After this first message, six more
descaling programmes are possible.

The descaling cartridge is available to
order from the Miele online shop or
directly from Miele (see back cover for
contact details).
If a descaling cartridge is not fitted, an
empty cartridge is fitted or an expired
cartridge is fitted, the machine needs
to be descaled using the
maintenance programme. To
machine
do this, the appropriate descaling
agent is required (see "Cleaning and
care - Descaling the appliance").
The descaling cartridge can remain
fitted even if the machine is not used for
a long time. Remove the cartridge
before transporting the coffee machine.
However, please note the following:
- Once filled with water, the descaling
cartridge has a maximum shelf life of
three weeks outside of the machine.
- It should be transported with care
and upright. Avoid shaking it.
Shaking or turning upside down
reduces the storage life and damages
the cartridge.
- The cartridge should be stored
upright, in a dark place and at room
temperature (16 – 38 °C).
Fitting the descaling cartridge
Risk of damage from spilt descaling
solution.
Sensitive surfaces and/or natural
floors can suffer damage.
When handling a cartridge which has
already been filled with water, ensure
that the descaling solution does not
come into contact with sensitive
surfaces.
