Miele CVA 2650 - Manual (Page 63)

Setting the water hardness
The hardness of the water used in the
coffee system must be determined and
programmed into the appliance. The
water hardness will determine how
frequently the unit must be descaled to
properly maintain the coffee system.
The machine monitors the volume of
water passing through it in conjunction
with the hardness of the water and will
indicate when descaling is necessary.
Your local water authority can inform
you of the hardness of your tap water or
you can measure the hardness yourself
using the enclosed test strip.
^ Dip the strip into your tap water for
one second, then shake off any
excess water.
The result will be evident after one
minute.
If your water hardness is greater
than 40 gr/gal (700 ppm), the water
must be mixed in equal parts with
non-carbonated mineral water to
prevent excessive lime scale build
up.
Never use distilled water.
