Water Hardness - Miele CM6x10 Operating Instructions Manual

Using for the first time

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)
The machine is programmed ex-works
to hardness level 3.

Measuring the water hardness level
You can determine the water hardness
yourself using the enclosed test strip.
Alternatively, your local water authority
will be able to tell you the hardness of
water in your area.
 Dip the test strip in your drinking
water for approximately one second,
then shake off any excess water. The
result will be evident after about
a minute.
