Descale - Miele DO 7860 Operating And Installation Instructions

Cleaning and care

Descale

The frequency of descaling will depend
on the water hardness level in your
area.
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 programmes.
The oven will count down in the display
the last 10 programmes that can be run
before it needs to be descaled. You will
then not be able to run any function or
automatic programme using moisture
assistance.
These functions can only be used again
after you have carried out a descaling
process. All other functions and
automatic programmes without
moisture assistance can still be used.
