Water hardness
To ensure that the steam oven works
correctly and to ensure that descaling is
carried out at the correct interval, it
must be set to the local water hardness
level. The harder the water is, the more
frequently the steam oven needs to be
descaled.
Contact your local water supplier to find
out your local water hardness range if
necessary.
If you are using bottled drinking water,
e.g. mineral water, use non-carbonated
water. Select settings according to the
calcium content. The calcium content is
given on the label of the bottle in mg/l
Ca
2+
or ppm (mg Ca
2+
/l).
The degree of hardness can be set
between
0.2 mmol/l (1° dH)
and
12.5 mmol/l (70° dH)
. The hardness level
is set to 2.7 mmol/l (15 °dH) at the
factory.
Set the water hardness level for your
area.
