The Water Softener
Water contains varying amounts of lime and mineral
salts depending on the area in which you live: these
are deposited on the dishes leaving white marks.
The higher the content of these salts, the harder your
water will be. The «hardness» level is measured on 2
equivalent scales: French Degrees or Clarke De-
grees.
Contact your local Water Authority to find the exact
water hardness level for your area.
The dishwasher is equipped with a softener which uses
special dishwasher salt to provide lime-free (softened)
water. The softener can treat water hardness up to 90
French degrees via 5 adjustment levels.
Find on the table below the level corresponding to the
hardness of your water and the required adjustments:
*The water softener is factory set at level 2 as this suits most users.
** If you use phosphate free detergents containing enzymes, use salt starting
from 6 Clarke degrees (7 French degrees).
Level 1
If your water is level 1 it is already soft and therefore
there is no need to use salt.
Levels 3 and 5 (water softener adjustment)
If your water is level 3 or 5, proceed as follows:
Slide out the lower basket and unscrew the cap of the
salt container; turn the two-position selector anticlock-
wise from position – to position
+ with the aid of a
knife or a screwdriver.
Levels 4 and 5 (adjustment on the machine)
If your water level is 4 or 5,
open the door and drill
membrane (A) on the up-
per left-hand corner of the
machine.
Filling with Salt
Only use salt designed specifically for use in dish-
washers. To fill with salt, unscrew the cap of the salt
container.
Pour about one litre of water inside the container, or
until it is full (this is necessary only before filling with
salt for the first time).
Then, using the funnel provided, pour in the salt until the
container is full (approx. 1,5 - 1,8 kg). Do not worry if
water over flows from the unit when filling with salt this
is quite normal.
Replace the cap making sure that there is no trace of
salt on the screw thread or on the gasket.
Screw the cap on tightly.
If you have inadvertently spilled salt select a wash
programme immediately after.
All that is then required is to periodically top up the
container with salt. You are reminded of this by a
green refill indicator on the cap of the salt container.
When the green indicator disappears, the water soft-
ener needs refilling with salt.
The salt container always has some water inside
which will normally overflow when refilling with salt.
Caution: Only fill with salt just before starting one of
the complete washing programmes (not the Rinse
and Hold programme). This will prevent any grains of
salt or salty water, which may have been spilled,
remaining on the bottom of the machine for any period
of time. This could cause corrosion.
