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.
Your local water authority will be able to
tell you 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 given 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 gpg (1°dH)
and
73 gpg (70°dH)
. The
hardness level is set to
16 gpg (15°dH)
by
default.
Set the water hardness level for your
area.
