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.
The hardness level is set to21°dH by
default.

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 descaler will be used.
