Water hardness
The combination 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
correct interval. The harder the water is, the more frequently the combination
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 mineral water, make sure it is not carbonated.
Adjust this setting depending on the calcium content. The calcium content is
specified on the label of the bottle in mg/l Ca
You can set the hardness level between
to
15 °dH
by default.
