Water hardness
If a descaling cartridge is not fitted
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.
Programme the coffee machine to the
water hardness level of your area so
that it functions correctly and does not
get damaged.
Contact your local water supplier to find
out your local water hardness range if
necessary.
If you are using bottled drinking water,
e.g. mineral water, select settings
according to the calcium content. The
calcium content is specified on the label
of the bottle in mg/lCa
2+
or ppm
(mgCa
2+
/l).
Do not use carbonated water.
Tip: If your water hardness is >21°dH
(3.8mmol/l), we recommend using
bottled drinking water instead
(<150mg/lCa
2+
). 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 machine is programmed ex-works
to hardness level3.
The machine has four programmable
levels:
°dH mmol/l ppm
(mg/l CaCO
3
)
