2. Operating instructions
Once the dishwasher has been correctly installed, prepare for use as
follows:
Adjust the water softening system;
Add the regenerating salt;

Add the rinse aid and detergent.
2.1 Using the water softening system
The amount of scale contained in the water
(water hardness index) can cause whitish
staining on the dry dishes, which tend to
become dull over time. The dishwasher is
equipped with an automatic softening
system which uses a special regenerating
salt to reduce the hardness of the water.
When using water of medium hardness, the regenerating salt container
should be refilled after approximately 20 washing cycles. The salt
container can hold approximately 1.7 Kg of salt in grains. Some models
are equipped with an optical no-salt indicator. In these models, the cap of
the salt container contains a green float which descends as the salt
concentration in the water drops. When the green float can no longer be
seen through the transparent cap, the container must be topped up with
regenerating salt. The container is situated at the bottom of the
dishwasher. After removing the lower basket, unscrew the salt container
cap by turning it anticlockwise and pour in the salt using the funnel
supplied with the dishwasher. Before replacing the cap, remove any salt
residues from around the opening.

When using the dishwasher for the first time, in addition to the salt it
is also necessary to add one litre of water to the container.
Each time the salt container is refilled, make sure that the cap is
securely closed. The mixture of water and detergent must never
penetrate the salt container, as this would compromise the operation
of theregeneration system. In theevent ofthisoccurring, the warranty
will be invalidated.
Only use regenerating salt specially formulated for domestic
dishwashers. If using salt tablets, do not fill the container
completely.
SALT

User instructions
12
Do not use table salt as it contains insoluble substances which, over
time, may damage the water softening system.
When necessary, refill the regenerating salt container before
starting the washing program. In this way, the excess saline
solution will be immediately removed by the water; the prolonged
presence of salt water inside the tank may lead to corrosion.
Be careful not to confuse the salt and detergent packages; adding
detergent to the salt container will damage the water softening system.
ADJUSTING THE
WATER SOFTENER
The setting can be adjusted using the
PROGRAM SELECTION
BUTTON (3). Keep the button pressed until the WATER HARDNESS
ADJUSTMENT INDICATOR LIGHT (4) flashes. The SELECTED
PROGRAM INDICATOR LIGHTS (2) indicate the current setting. Each
press of the button modifies the setting according to the sequence in the
following table:
>
After carrying out the adjustment or displaying the current setting, if you
do not touch the button for a few seconds the dishwasher will
automatically exit from adjustment mode and return to the standard
operating mode.

2.2 Using the rinse aid and detergent dispensers
The detergent and rinse aid
dispensers are situated on the inner
part of the door: the detergent
dispenser is on theleft, and therinse
aid dispenser is on the right.
With the exception of the SOAK program, before every washing cycle it is
necessary to add the required amount of detergent to the detergent
dispenser. The rinse aid, on the other hand, should only be added as
required.

User instructions
14
ADDING THE RINSE AID
The rinse aid helps the dishes dry faster and
prevents the formation of scale deposits and
staining; it is automatically added to the water
during the final rinse cycle, from the container
situated on the inner side of the door.
To add rinse aid:
Open the dispenser by pressing and lifting the tab on the cover.
Fill the dispenser with rinse aid. Top up again when the rinse aid
indicator light turns on.
Close the cover, a click indicates when it is closed.
Use a cloth to remove any spillage of rinse aid which might lead to
the formation of excess foam.

ADDING THE DETERGENT
To open the detergent dispenser cover, lightly press button
P
. Add the
detergent or tablet and close the cover by sliding it until it stops, indicated
by a click.
The dispenser will open automatically during the wash cycle.
Only add the detergent
(also in tablet form) if the dispenser is dry
When a program with hot prewash is selected (see program table),
extra detergent must be placed in the cavity G/H (depending on
models).
Use only detergents specially formulated for dishwashers. The
detergent packs must be sealed and stored in a dry place to prevent
the formation of lumps which may negatively affect washing results.
Once opened the detergent packs should not be kept for too long,
otherwise the detergent loses its effectiveness.
Do not use detergents for washing dishes by hand because they may
affect the operation of the dishwasher.
Add the correct amount of detergent. An insufficient amount of
detergent will result in a partial removal of dirt from the dishes,
whereas an excessive amount is wasteful and does not improve the
washing results.
For the safeguarding of the environment we recommend the use of
phosphate- and chlorine free detergents.

The introduction of detergent into the rinse aid dispenser, even in
liquid form, will damage the dishwasher.
2.3 General warnings and recommendations
Before using the dishwasher for the first time, it is advisable to read the
following recommendationsconcerning dishtypesto be washed and their
loading.
There are generally no constraints on the washing of domestic dishes,
but in certain cases it is necessary to take their characteristics into
account.
Before loading the dishes into the baskets it is necessary to:
remove coarse food remains: e.g. bones, fish-bones, etc. whichmay
clog the filter or damage the wash pump.
soak any pots or pans with burnt-on food remains on the bottom to
facilitate removal, then load them into the LOWER BASKET.
There is no need to pre-wash the dishes under running water before
loading them into the baskets since this only wastes water.
Correct loading of the dishes helps ensure optimal washing results.

User instructions
18
WARNING!
Make sure that the dishes are securely in place so that they cannot
tip over or obstruct the rotation ofthe spray arms during the washing
cycle.
Do notplace very small objects in the baskets as thesecouldfall and
obstruct the spray arms or the wash pump.
Containers such as cups, bowls, glasses and pots should always be
loaded with the opening facing downwards and with any cavities at
an angle, to allow the water to drain out.
Do not stack dishes or place them in such a way that they cover one
other.
Do not place glasses too close together because they may knock
against each other and break, or there might be staining at the point
where they touch.
MAKE SURE that the items being washed are dishwasher-safe.
Items which are not dishwasher-safe:
Wooden dishes, pots or pans: thesemay be damaged by the high
washing temperatures.
Handcrafted items: these are rarely suitable for washing in a
dishwasher. The relatively high water temperatures and the
detergents used may damage them.
Plastic dishes: heat resistant plastic dishes must be washed in the
upper basket.
Dishes and objects in copper, tin, zinc or brass: these tend to
stain.
Aluminium dishes: items made from anodised aluminium may lose
their colour.
Silverware: silver items may stain.
Glass and crystal: in general, glass and crystal objects can be
washed in the dishwasher. However, certain types of glass and
crystal may become dull and lose their clearness after many
washings. Therefore, for these items we recommend usingthe least
aggressive program available.
Decorated items: the decorated objects available on themarket are
generally able to withstand washing in the dishwasher, although the
colours may fade after a great many washes. If in doubt as to the
fastness of the colours, it is advisable to wash just a few items at a
time for approximately one month.

2.4 Using the baskets
The dishwasher has a capacity of 13 place-settings, including serving
dishes.
LOWER BASKET
The lower basket receives the full force of the lower spray arm, and should
therefore be used for the “toughest” items with a heavier degree of soiling.
All types and combinations of loads are
permitted, provided that the dishes, pots and
pans are arranged with all the soiled surfaces
exposed to the water jets coming from the
bottom.
With fixed supports
To make the most of the space inside the
basket when loading large items, certain
models are equipped with tip-up supports for
plates in 2 or 4 sections.
With tip-up supports
BOTTOM BASKET INSERTS
Some models are equipped with bottom basket inserts which improve
the drying of dishes. The inserts are supplied in the accessories bag; to
use them, simply fit them into place as shown.

User instructions
20
LOADING THE LOWER BASKET
Carefully load flat plates, soup plates, dessert and serving dishes,
positioning them vertically. Pots, pans and their covers must be loaded
upside down. When loading soup plates and dessert bowls, be sure to
leave a gap between them.
Loading examples:
UPPER BASKET
The upper basket should be loaded with small or medium-sized items
such as glasses, small plates and saucers, tea or coffee cups, shallow
bowls and light objects. If the upper basket is used in the lowermost
position, it can also be loaded with serving dishes, provided they are only
lightly soiled.
LOADING THE UPPER BASKET
Load plates facing forward; cups, bowls etc. must always be facing
downwards. The left side of the basket can be loaded with cups and
glasses on two levels. In the centre section, plates and saucers can be
loaded vertically into the supports provided.
Loading examples:
