5-1.Positioning the appliance
Positioning the appliance in the desired location. The back of the appliance should rest against
the wall, 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.
5-2.Leveling the appliance
Once the appliance is positioned, adjust the feet (screwing them in or out) to adjust the
dishwasher, making it level. The appliance should not be inclined more than 2°. If the appliance is
level, it will help ensure proper performance.
5-3.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 inlet can get blocked and damage
the appliance.
fig.A
Warning
The appliance is to be connected to the water mains
using new hose-sets and that old hose-sets should not
be reused.
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.

7. How to load the salt
7-1.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.
7-2.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 “J” lights, you must
fill the salt.
● emove 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.
J
Important
To prevent the formation of rust, load the salt just before beginning a wash cycle.
7-3.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.

10.Arranging crockery, glasses, etc. in 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.
10-1.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.
fig.D
E1 E2 E3
fig.E
● Pots, serving bowls, etc. must always be placed
face down(see fig.D).
● Deep pots should be slanted to allow the water
to flow out.
● Some models: the lower rack features fold down
tine rows (see fig.E) so that larger or more pots
and pans can be loaded.
● The silverware basket can be doubled (see fig.F)
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.

10-2.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).
● The dishes and cookware shall be arranged, 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.G).
(Some models)
Adjust the upper basket to the higher level and you
have more space to accommodate those taller pans
and trays in the bottom basket.
10-3.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
swivelled in or out as required(see fig.H).
10-4.Knife rack
The knife rack clips onto the side of the top basket,
giving you the freedom to wash your large sharp
knives separately and out of harm’s way (see fig.I).
fig.G
fig.H
Warning:
knives and other utensils with sharp points must
be loaded in the basket with their points down or
placed in a horizontal position.

13. How to keep your dishwasher in shape
After every wash
After every wash, turn off the water supply of 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 switch off the appliance, and 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, It is recommended that you 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 white 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.

14. Care and maintenance
Regular inspection and maintenance of your appliance helps to prevent problems
from occurring.This saves time and aggravation.You should therefore carefully
inspect the inside of your dishwasher from time to time.
14-1.Overall condition of appliance
● Check that no grease or scale has accumulated on the inside of the dishwasher.
If you discover any deposits:
● Clean the interior of the dishwasher thorughly with a dishwasher detergent solution.
14-2.Dishwasher salt
Check the LOW SALT indicator “ J ”. Top up with
salt, if required.
14-3.Rinse-aid
Check the LOW RINSE AID indicator “ I ”, on the
front panel. Top up with rinse-aid,if required.
14-4.Filters
The filters “ 8”,“ 9” prevent larger particles of food
in the water from reaching the pump.These particles
may occasionally block the filters.
● When the appliance has finished washing, check
the filters for particles of food and, if required,
clean.
● After undoing the coarse micro-filter “ 8 ” , the
filter unit “9” can be removed. Remove any
particles of food and rinse the filters under running
water.
● Insert the filter unit “ 9 ” and tighten the coarse
micro-filter.

Notice:
Before cleaning, make sure that the plug of the
appliance has been removed from the socket.
14-5.Spray arms

and “ 11 ” and the arm mountings.
● Inspect the nozzles in the spray arms for blocked
holes due to remnants of food.
