Water softener
To achieve good cleaning results, the
dishwasher needs soft water (water that
is low in minerals). Hard water results in
calcium deposits on dishware and in
the dishwasher.
If your tap water hardness is above 4 °d
(4 gr/gal) the water should be softened.
The built-in water softener is designed
for this purpose. The water softener is
suitable for a water hardness up to
70 °d (73 gr/gal).
– If using "Tab" detergent products you
do not need to add salt, depending
on the water hardness ß 22 gr/gal
(21 °d) (see "Detergents").
– The dishwasher must be correctly
programmed to match the hardness
of your water.
– Your local water authority will be able
to advise you of the exact water
hardness level in your area.
If the hardness of your local supply
is constantly lower than 4 °d (4
gr/gal), you do not need to add
water softener salt. However the
water hardness level must still be
programmed.
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]).
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)
The water hardness was programmed
at 1 °d (1 gr/gal) by factory default.
