Limescale builds up in the coffee
system during use. The limescale
buildup in the system depends on the
hardness of your local water supply.
Limescale must be removed regularly.
The system guides you through the
descaling process. Various instructions
appear in the display, e.g. you are
prompted to empty the drip tray or fill
the water tank.
Descaling is absolutely necessary
and takes approximately 20 minutes.
During the descaling program, water
containing descaling agent runs out of
the main dispenser and the hot water
dispenser. This is followed by a
working-in period before a little more
water with descaling agent is
dispensed, etc.
The coffee system will remind you via
the display when the descaling
program needs to be carried out. The
following message will appear in the
display: "No. of uses until appliance
needs descaling: 50". The remaining
number of portions that can be made
before descaling will show in the
display after each beverage is made.

Touch "OK" to confirm this message.
When the number of remaining drinks
is 0, the coffee system will lock. The
display will read, "Please descale".
You can turn the coffee system off if
you do not want to run the descaling
program at this time. However, no more
drinks can be prepared until the
descaling program has been
completed.
