Miele CM7500 User Manual

Water hardness
74
If the descaling method has been set
to Manual descaling, the coffee machine
will need to be set for the local water
hardness level. A prompt to run the
descaling programme will then appear
in the display at the right time.
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.
The machine has four programmable
levels:
