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 ma-
chine will need to be descaled.
The coffee machine measures the
amount of water used and steam made.
Depending on the level of water hard-
ness set, more or fewer drinks can be
dispensed before the appliance needs
to be descaled.
Program the coffee machine to the wa-
ter 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.
Your local water authority will be able to
tell you the hardness of water in your
area.
The water hardness level is set to 3 at
the factory.
You can program four hardness levels
on the machine:
°dH
gr/gal
0 - 8.4
0 – 8.7
8.4 – 14
8.7 - 14.6
14 – 21
14.6 - 21.9
> 21
>  21.9
* The water hardness settings in the display
may differ from the water hardness level in
your area. To set the correct water hardness
level for your area always refer to the values
in the chart.
