Water softener
To achieve good cleaning results, the
dishwasher needs soft water. Hard
water results in calcium deposits on
dishware and in the dishwasher.
If your tap water hardness is above
8 gr/gal (140 ppm), the water should be
softened. This takes place automati
-
cally in the unit’s integrated water soft
-
ener.
–
Your local water authority will be able
to advise you of the water hardness
level in your area.
– The dishwasher must be pro-
grammed to correspond to the water
hardness in your area.
– The water softener must be filled with
dishwasher salt for reactivation.
If your water hardness is consistently
lower than 8 gr/gal (140 ppm), you do
not need to add dishwasher salt. How-
ever, the dishwasher must still be pro-
grammed to correspond to the local
water hardness.
Where the water hardness fluctuates
e.g. between 9 - 17 gr/gal (160 - 310
ppm), always program the machine to
the higher value, 17 gr/gal (310 ppm) in
this example.
If there is a fault, it will help the service
technician to know the hardness of your
local water supply.
