Water hardness

Your dishwasher is fitted with a water
softener.
- You should programme the
dishwasher to the correct water
hardness for your area.
- Your local water authority will be able
to advise you on the water hardness
level in your area.
- Where the water hardness fluctuates,
e.g. between 1.8 and 2.7 mmol/l (10–
15 °dH – German scale), always
programme the dishwasher to the
higher value (2.7 mmol/l or 15 °dH in
this example).
If the water hardness in your area is
available in a unit other than °dH, you
can convert the values as follows:
1 °dH = 0.18 mmol/l = 1.78 °fH
