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
quantity of water and steam used. The
number of drinks which can be
dispensed before the machine needs to
be descaled will depend on the water
hardness level set.
Set the water hardness level on the
coffee machine to the water hardness
level for the local area to ensure that
the machine functions correctly and is
not damaged. This will ensure that the
reminder to descale the machine will
appear in the display at the correct
time.
The machine has four programmable
levels:
Water hardness
