Positioning the appliance
Positioning the appliance in the desired location. The back should rest against the wall
behind it, and the sides, along the adjacent cabinets or wall. The dishwasher is equipped
with water supply and drain hoses that can be positioned to the right or the left to facilitate
proper installation.
Leveling the appliance
Once the appliance is positioned, adjust the feet (screwing them in or out) to adjust the
dishwasher, making it level. In any case, the appliance should not be inclined more than 2°.
If the appliance is level, it will help ensure proper performance.
Cold water connection
Connect the water supply hose to a threaded 3/4
(gas) connector, making sure that it is fastened
tightly in place (see fig.A).
Some models are fitted with an "Aquastop" water
supply hose (see fig.B) in which the small filter is
already housed in the threaded end.
If the water pipes are new or have not been used
for an extended period of time, let the water run to
make sure that the water is clear and free of
impurities. If this precaution is not taken, there is a
risk that the water inlet can get blocked and
damage the appliance.

Drain hose connection
Insert the drain hose into a drain pipe with a minimum diameter of 4cm, or let it run into the
sink, making sure to avoid bending or crimping it. If necessary, fit a syphon trap (U-bend)
with a connecting piece for the drain hose (fig.C). The free end of the hose must be at a
height between 40 and 100 cm and must not be immersed in water.
Electrical Connection
After making sure that the voltage and frequency values for the current in the home
correspond to those on the rating plate (located on the stainless steel inner door of the
appliance) and that the electrical system is correct for the maximum voltage on the rating
plate, insert the plug into an electrical socket which is earthed properly (the earthing of the
appliance is a safety requirement mandated by law).
If the electrical socket to which the appliance must be connected is not appropriate for the
plug, replace the whole cable, rather than using adaptors or the like as they could cause
overheating and burns.

6. How to fill the salt
Salt
The hardness of the water varies from place to place. If hard water is used in the
dishwasher, deposits will form on the dishes and utensils.
The appliance is equipped with a special softener that uses a salt specifically designed to
eliminate lime and minerals from the water.
Loading the salt into the container
Always use salt intended for use with dishwashers.
The salt container is located beneath the lower rack
and should be filled as follows:
--When the low salt indicator “1” lights, you must fill
the salt.
--Remove the lower rack and then unscrew and remove
the cap from the salt container;
--If you are filling the container for the first time, fill it with
water;
--Place the end of the funnel (supplied) into the hole and
introduce about 2 kg of salt. It is normal for a small
amount of water to come out of the salt container.
--Carefully screw the cap back on.

Adjusting salt consumption
The dishwasher is designed to allow for adjusting the
Amount of salt consumed based on the hardness of
the water used.
This is intended to optimize and customize the level
of salt consumption so that it remains at a minimum.
To adjust salt consumption, proceed as follows:
--Unscrew the cap from the salt container;
--There is a ring on the container with an arrow on
it (see figure to the side),
--If necessary, rotate the ring in an anticlockwise direction from the "-" setting towards the
"+" sign, based on the hardness of the water being used.
It is recommended that adjustments be made in accordance with the following table:

7. How to fill rinse aid and detergent dispenser
7.1 how to fill rinse aid
Rinse aid
This product makes dishes sparkle and helps them to dry
without spotting. The dispenser is located on the inside
panel of the door .
When the low rinse aid indicator “ H ” lights , you must
load rinse aid .
Loading the rinse aid
Regardless of the type of detergent dispenser installed
on your appliance, you must proceed as indicated below
when loading the rinse aid.
To open the dispenser, turn the "2" cap in an
anti-clockwise direction and then pour in the rinse aid,
making sure not to overfill. The amount of rinse aid used
for each cycle can be regulated by turning the " 3" dose
adjustor, located beneath the "2" cap, with a screwdriver.
There are 6 different settings; the normal dosage setting
is 3.
7.2 How to fill detergent dispenser
Detergent
Detergent specifically intended for use with dishwashers
must be used. The dispenser must be refilled before the
start of each wash cycle following the instructions
provided in the "Programme overview". The detergent
dispenser is located on the inside panel of the door.

Bom: FA06D0E03/FA06D0E04 Edition:2008-05

Page 13 / 37
Loading the detergent
--To open the " 5 " cover on the dispenser, press the " 6 "
button.
--The detergent for the wash cycle should be poured into
the " 7 " compartment.
--The detergent for the pre-wash cycle should be poured
into the “ 8 ” compartment.
--After the detergent has been placed in the dispenser,
close the cover and press down until it clicks in place.
8. Loading the dishwasher
Before placing the dishes in the dishwasher, remove larger food particles to prevent the
filter from becoming clogged, which results in reduced performance.
If the pots and pans have baked-on food that is extremely hard to remove, we recommend
that they are soaked before washed. This will eliminate the need for extra wash cycles.
Pull out the rack to load the dishwasher.
How to use the lower rack
We recommend that you place the most difficult
to clean items on the bottom rack: pots, pans, lids,
serving dishes and bowls, as shown in the figure
to the right.
It is preferable to place serving dishes and lids
on the sides of the racks in order to avoid
blocking the rotation of the top spray arm.
--Pots, serving bowls, etc. must always be placed
face down
--Deep pots should be slanted to allow the water to
flow out.

How to use the upper rack
The upper rack is designed to hold more
delicate and lighter dishware, such as glasses,
cups and saucers, plates, small bowls and
shallow pans (as long as they are not too dirty).
--Position the dishes and cookware so that
they do not get moved by the spray of water.
--The upper rack can be adjusted for height
by using the knobs located on both sides of
the rack itself (see fig.F).
Adjust the upper basket to the higher level
and you have more space to accommodate
those taller pans and trays in the bottom
basket.
Shelf
Lean tall glasses and those with long stems
against the shelf not against other items to be
washed.
Place glasses, cups and small bowls on the
additional cup rack.
The additional cup rack can be swiveled in or
out as required (see fig.G).

12. How to keep your dishwasher in shape
After Every Wash
After every wash, turn off the water supply (not necessary for models with “Aquastop” ) the
appliance and leave the door slightly ajar so that moisture and odors are not trapped inside.
Remove the plug
Before cleaning or performing maintenance, always remove the plug from the socket. Do
not run risks.
No solvents or Abrasive Cleaning Products
To clean the exterior and rubber parts of the dishwasher, do not use solvents or abrasive
cleaning products. Rather, use only a cloth and warm soapy water.
To remove spots or stains from the surface of the interior, use a cloth dampened with water
and a little while vinegar, or cleaning product made specifically for dishwashers.
Moving the Appliance
If the appliance must be moved, try to keep it in a vertical position. If absolutely necessary,
it can be positioned on its back.
Seals
One of the factors that cause odors to form in the dishwasher is food that remains trapped
in the seals.
Periodic cleaning with a damp sponge will prevent this from occurring.
The door should not be left in the open position since this could present
a tripping hazard.
When You Go on Holiday
When you go on holiday, it is recommended that you run a wash cycle with the dishwasher
empty and then remove the plug from the socket, turn off the water supply and leave the
door of the appliance slightly ajar. This will help the seals last longer and prevent odors
from forming within the appliance.
