Water Hardness - Miele CM7300 Operating Instructions Manual

Using for the first time
After setting the machine up you can
make your first drinks. Coffee beans
can be ground up to five times, as the
coffee machine checks whether there
is sufficient ground coffee to make an
aromatic cup of coffee, and will grind
more beans as necessary.

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 used and steam made.
Depending on the level of water
hardness set, more or fewer drinks can
be dispensed before the machine
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. A prompt to descale the
machine will then appear in the display
at the correct time.
The machine has four programmable
levels:
Water hardness
0 - 8.4 °dH
(0 -1.5 mmol/l)
8.4 - 14 °dH
(1.5 - 2.5 mmol/l)
14 - 21 °dH
(2.5 - 3.7 mmol/l)
> 21 °dH
(> 3.7 mmol/l)
