Cleaning and care of the oven

Descale
The steam system should be descaled
regularly (frequency will depend on the
on-site water hardness).
The descaling process can be run at
any time.
However, to ensure that the oven
functions correctly, you will be
automatically prompted to run the
descaling process for the steam
injection system after a certain number
of programs.
The oven will count down on the display
the last 10 programs that can be run
before it needs to be descaled. You will
then not be able to run any operating
modes or MasterChef automatic
programs using moisture injection.
These operating modes can only be
used again after you have carried out
the descaling process. All other
operating modes and MasterChef
automatic programs without moisture
injection can still be used.
Descaling process sequence
Once the descaling process has been
started, it must be completed through
to the end. It cannot be canceled.
The descaling process takes approx.
90minutes and consists of several steps:
1. Preparing for the descaling process
2. Drawing in the descaling agent
3. Activation phase
4. Rinse 1
5. Rinse 2
6. Rinse 3
7. Residual moisture evaporation
Preparing for the descaling process
You will need a container of approx.
4cups (1liter) capacity.
A plastic tube (with suction cup) is
supplied with your oven so that you
do not have to hold the container with
the descaling agent underneath the
water intake pipe.
We recommend using the descaling
tablets supplied. They have been
specially developed for Miele for
optimum cleaning results.
Tip: Miele descaling tablets are
available to order from the Miele web
shop, from the Miele Customer Service,
or from your Miele dealer.
Other descaling agents, which contain
other acids besides citric acid and/or
other undesirable substances, such as
chlorides, could cause damage.
Moreover, the descaling result
required could not be guaranteed if
the descaling agent was not of the
appropriate concentration.
 Fill the container with approx. 2 1/2
cups (600ml) of cold tap water and
completely dissolve one descaling
tablet in it.
