Water hardness
Water hardness is an indication of the
amount of minerals dissolved in water.
The more minerals in the water, the
higher the water hardness. The harder
the water is, the more frequently the
coffee machine needs to be descaled.
The coffee machine measures the
amount of water used and steam made.
Depending on the level of water
hardness set, more or fewer drinks can
be dispensed before the appliance
needs to be descaled.
Program the coffee machine to the
water hardness level of your area so
that it functions correctly and does not
get damaged. A prompt to descale the
machine will then appear in the display
at the correct time.
Your local water authority will be able to
tell you the hardness of the water in
your area.
The water hardness level is set to 3 at
the factory.
The appliance has 4 programmable
hardness levels:
