Water Hardness - Miele CVA 6800 Operating And Installation Instructions

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 system
will need to be descaled.
The coffee system 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 system 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 des‐
cale the appliance.
You can program four hardness levels
on the machine:

Determining the water hardness
You can measure the water hardness

water in your area.
