Water hardness

If a descaling cartridge is not installed
and you descale the coffee machine
using descaling tablets, the machine
should be set to the local water
hardness. A prompt to descale the
machine will then appear in the
display at the correct time.
Program the coffee machine to the
water hardness level of your area so
that it functions correctly and does not
get damaged.
Your local water authority will be able to
tell you the hardness of the water in
your area.
If you are using bottled drinking water,
e.g., mineral water, select settings

(21°dH), we recommend using bottled
drinking water instead (< 150 mg/

l Ca ). This will mean your coffee
machine will need to be descaled less
often and there will be less impact on
the environment because less descaling
agent will be used.
The water hardness level is set to 3 at
the factory.
The machine has four programmable
hardness levels:
