4. Installation
4-1.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.
4-2.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.
4-3.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).
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 inletcan get blocked and damage the appliance.
4-4.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.B). The free end of the hose must be at a height between
40 and 100 cm and must not be immersed in water.
Warning:
The appliance is to be connected to the water mains using new hose-sets and that old
hose-sets should not be reused.
Attention:
The connecting piece for syphon trap (U-bend) must be securely fastened to the wall to
prevent the drain hose from moving and allowing water to spill outside the drain.

4-5.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.
ELECTRICAL CONNECTION (UK ONLY)
For your safety please read the following information.
Warning: This appliance must be earthed.
The appliance must be connected to a 220-240 volts 50 cycle AC supply by means of a three pin
socket,suitably earthed and should be protected by a 13 amp fuse in the plug.
The appliance is supplied with a rewireable 13 amp 3-pin plug fitted with a 13-amp fuse. Should
the fuse require replacement, it must be replaced with a fuse rated at 13 amp and approved to
BS1362.
If the mains plug is unsuitable for the socket outlet in your home or is removed for any other
reason, then the cut off plug should be disposed of safely to prevent the hazard of electric
shock.Remove the fuse before disposal.
There is a danger of electric shock if the cut off plug is inserted into any 13-amp socket outlet.
How to wire a 13 amp plug.

6. How to fill the salt
6-1.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.
6-2.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.
6-3.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:
Important:
To prevent the formation of rust, load the salt just before beginning a wash cycle.

7. How to fill rinse aid and detergent dispenser
7-1.How to fill rinse aid
7-1-1.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 .
7-1-2.Loading the rinse aid
Regardless of the type of detergent dispenser installed on your
appliance, you must proceed as indicated below when loading the rinseaid.
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
7-2-1.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.
7-2-2.Loading the detergent
To open the " 4 " cover on the dispenser, press the " 5 " button.
The detergent for the wash cycle should be poured into the " 6 "
compartment.
The detergent for the pre-wash cycle should be poured into the “ 7 ” compartment.
After the detergent has been placed in the dispenser, close the cover
and press down until it clicks in place.
Important:
Proper dosage of the rinse aid improves drying. If drops of water remain on the dishes
or spotting occurs, the dosage adjustor should be turned to a higher setting. If the
dishes have white streaks, turn the dosage adjustor to a lower setting.
Notice:
To facilitate closing the cover, remove any excess detergent on the edges of the dispenser.

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.
8-1.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 (see fig.C)
Deep pots should be slanted to allow the water to flow out..
The silverware basket can be doubled (see fig.D) so that
only one section may be used when the silverware load is
light. This also makes space for additional pots and pans
and it can also be placed in the upper rack.
Silverware should be placed in the silverware basket with
the handles at the bottom; if the rack has side baskets, the
spoons should be located individually into the appropriate
slots. Especially long utensils should be placed in the horizontal
position at the front of the upper rack.
8-2.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.

knives and other utensils with sharp points must be loaded in the basket with their

The upper rack can be adjusted for height by using the knobs
located on both sides of the rack itself (see fig.E).
Adjust the upper basket to the higher level and you have
more space to accommodate those taller pans and trays in
the bottom basket.
8-3.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.F).
