Water Hardness - Miele CM 6100 Operating Instructions Manual

Before 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 appliance
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. At the correct time a
prompt will then appear in the display
to descale the appliance.
The machine has four programmable
levels:

Measuring water hardness
You can measure 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 strip in your drinking water for
approximately one second, then
shake off any excess water. The
result will be evident after about a
minute.
Now you can set the water hardness for
your coffee machine.
