Water hardness
Your dishwasher is fitted with a water
softener.
- The dishwasher must be pro-
grammed to the correct water hard-
ness for your area.
- Your local water authority will be able
to advise you of the water hardness
level in your area.
- Where the water hardness fluctuates,
e.g., between 10 and 16gr/gal (10–
15°dH – German scale), always pro-
gram the dishwasher to the higher
value (16gr/gal or 15°dH in this ex-
ample).
If the water hardness in your area is
available in a unit other than °dH, you
can convert the values as follows:
1°dH = 0.18mmol/l = 1.04 gpg
