Water hardness

The water hardness level indicates how
much calcium is dissolved in the water.
The higher the calcium content, the
harder the water, and the harder the
water, the more often the coffee
machine will need to be descaled.
The coffee machine measures the
amount of water and steam used.
Depending on the level of water
hardness set, more or fewer drinks can
be dispensed before the appliance
needs to be descaled.
Programme the coffee machine to the
water hardness level of your area so
that it functions correctly and does not
get damaged. At the correct time a
prompt will then appear in the display
to descale the appliance.
The machine has four programmable
levels:
