Water hardness
The steam oven must be adjusted to
the local water hardness level to ensure
that it works correctly and to ensure
that descaling is carried out at the cor-
rect interval. The harder the water is,
the more frequently the steam oven
needs to be descaled.
Contact your local water supplier to find
out the hardness of the water in your
area.
If you use bottled water, such as min-
eral water, make sure it is not carbon-
ated. Adjust this setting depending on
the calcium content. The calcium con-
tent is specified on the label of the
bottle in mg/l Ca
2+
or ppm (mg Ca
2+
/l).
You can set the hardness level between
1 °dH
and
70 °dH
. The hardness level is
set to
15 °dH
by default.
Select your local water hardness on
the appliance.

OK
