Setting the water hardness
For trouble-free operation of the coffee
machine, and to ensure that the
descaling reminder appears in the
display at the appropriate time, it is
important to set the water hardness
level. 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 result will
be evident after about a 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.
The machine has four programmable
levels:
–
Soft:
Local water hardness level 1
0-3°d (0-0.6 mmol/l)
Water through-flow: approx. 100 l
Steam through-flow: approx. 120
min.
– Medium:
Local water hardness level 1
4-7°d (0.7-1.3 mmol/l)
Water through-flow: approx. 80 l
Steam through-flow: approx. 90 min.
– Hard:
Local water hardness level 2
7-14°d (1.3-2.5 mmol/l)
Water through-flow: approx. 60 l
Steam through-flow: approx. 60 min.
–
Very hard:
Local water hardness levels 3-4
14-21°d (2.5-3.8 mmol/l) or more
Water through-flow: approx. 40 l
Steam through-flow: approx. 30 min.

Select "Settings F" from the Main
menu, and then touch the OK sensor.

Use the arrow sensors to highlight
"Water hardness" and then touch the
OK sensor.
