Water hardness
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 4 °d
(4 gr/gal [US]), the water should be
softened.
– Your local water authority will be able
to advise you of the water hardness
level in your area.
– The dishwasher must be
programmed to correspond to the
water hardness in your area.
– In areas where the water hardness
fluctuates (e. g. 37 - 50 °d
[39 -52 gr/gal]) always program the
machine to the higher value (in this
example 50 °d [52 gr/gal]).
It is useful to know your water hardness
so that you can provide the service
technician with this information in the
event of any service calls.
If there is a fault, it will help the service
technician to know the hardness of your
local water supply.
Please note your water hardness
below:
°d (gr/gal)
Before using for the first time
The water hardness factory setting is
15°d (16 gr/gal).
If this setting matches your water
hardness you need not read any
further.
However, if you have a different water
hardness you must adjust the water
softener to match your water hardness.
