Setting the water hardness
For trouble-free operation of the coffee machine, and to
ensure that the descaling reminder appears in the right
display at the appropriate time, it is important to programme
the machine for the water hardness level in your area. 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
machine will need to be descaled.
The machine measures the amount of water which has been
taken in (including the amount required for producing steam).
The amount of water which the machine can use before it
needs to be descaled will depend on the water hardness
level set. Less water will be used in hard water areas than in
soft water areas.
Your local water authority will be able to tell you the hardness
of water in your area. Alternatively, you can measure the
hardness yourself using the enclosed test strip:
^
Dip the strip in your drinking water for approximately a
second, then shake off any excess water.
The results will be evident after about 1 minute.
If the water is harder than 40 °d / 7.0 mmol/l, limescale will
build up more rapidy than with soft water. Descaling will
need to be carried out more regularly than stated to
prevent limescale damage to the machine.
Use programming option "Water hardness" to programme in
your water hardness level.
