4.2 Water hardness

Depending on the water hardness
in your region, or if you have not
inserted a filter (see chapter 4.1),
the machine needs descaling
sooner or later. So that the system
can indicate correctly when des -
caling is necessary, you must
enter the correct water hardness
settings before the first use.
The default setting is level 3.
First, test your water with the test
strips provided:
Dip the strip into the water and
then shake it lightly off.
After about a minute you can
read the result by counting the red
dots on the test strip.
The settings corresponding to
the different levels of hardness are
as follows:
Test strip / hardness level
= Display
1 red dot / 1–7°
= "HARDNESS LEVEL 1"
2 red dots / 8–14°
= "HARDNESS LEVEL 2"
3 red dots / 15–21°
= "HARDNESS LEVEL 3"
4 red dots / > 21°
= "HARDNESS LEVEL 4"

Note: If none of the dots turn red
on the test strip, please set level 1.
Press the program key 'P' to
enter programming mode.
Press the > key until "PROGRAM
W. HARD." appears (it will not
appear if the filter setting is on
"FILTER YES" – see chapter 4.1).
Press the 'ok' key.
Press the > key until the ap -
propriate level appears in the
display.
Press the 'ok' key to confirm.
The display reads: "PROGRAM W
HARD.".

programming mode to change
other function settings or press
'exit' to leave programming mode.

ature to "NORMAL", "HIGH" or
