1.2 Washing programs
Before starting a washing program make sure that:
The water supply tap is open.
The softener container contains regenerating salt.
The correct amount of detergent has been added to the
dispenser.
The baskets have been correctly loaded.
The spray arms are able to rotate freely and without
obstruction.
The dishwasher door is securely closed.
Warning:
during the initial phase of the washing program, the operation of sprayers
is not perceived because they start rotating about 5 minutes after the start.
This is the normal operation of the washing cycle.
CHILD SAFETY DEVICE
(on some models only)
Press the button to activate this device (the light comes on). When it is
active, the beeper sounds three times to confirm that the door is about to
open. So in this case, to open the door keep pressing until the 3rd beep,
then release at once. If the pressure is continued after the third beep, the
door does not open and the operation has to be repeated.
OPTION SELECTION
Options are selected by pressing the relative button by the symbol of the
option required; the light comes on to confirm that the option has been
activated.
It is not possible to select any options when the soak program
is being used.
All options except "Flexi Tabs" are disabled at the end of the
wash cycle. To disable the “Flexi Tabs” option, press the
relative button (the light goes out).
All options, including "Flexi Tabs" are disabled when a program
is CANCELLED after it has begun.

ADDITIONAL OPTIONS
Some models feature additional options, activated by pressing two
buttons simultaneously. In this case, two lines in the control panel
graphics link the symbol of the additional option to the two buttons to be
pressed simultaneously to enable it. (e.g. “Flexi Tabs” in this illustration)
QUICK TIME OPTION
Select this option together with any washing program (except the soak
program)toSHORTENthecycle. To activatethis option, press button (light
comes on) after selecting the program required.
The option is automatically deactivated at the end of the program.
ENERSAVE OPTION
This option further reduces energy consumption by opening the door at
the end of the cycle for more effective drying. At the end of the wash an
automatic device releases the door, which slowly opens by a few
centimetres. This allows optimal drying even with low rinsing
temperatures, for significant energy saving.
The dishwasher remains in an idle state between the rinse stage and the
end of the cycleto allowproper drying (thedisplayshowsthe timeleft until
the end of the cycle). Opening the door at this stage causes the cycle to
stop and ends the program.
The program end is signalled by a short beep and the flashing of the
indicator lights for programs 4 and 5.
Enersave
is activated automatically if the selected program is
compatible with the option. It can be deactivated before the program is
started.
When the function is activated, opening of the door
must notbe impeded
in any way; do not leave anything in the necessary space in front of the
door to allow it to open. Do not force the door lock before the end of the
cycle is signalled, as this would damage the mechanism.

ULTRA CLEAN
The "ULTRA CLEAN" program prolongs the final hot rinse to ensure a
further reduction in the bacteria level. If the temperature in the tank falls
during this stage of theprogram (e.g. because thedoor is opened or dueto
a power blackout), the light of the option and the program lights (2) flash to
warn that the additional washing phase has not been completed
successfully. This does not mean that the wash program has been less
effective than usual.
SPREAD HALF LOAD
Suitable when there are not many dishes to be washed, it saves energy
andreduces theprogram duration. Placedishes in both basketsthenload
the detergent dispenser than less than the normal amount for a full load.
Flexi Tabs
Specifically for washing with combination detergents intablets, which also
contain salt and rinse aid (3in1) or other agents such as glass protector,
steel rinse aids, etc. (4in1, 5in1…). When this option is selected, salt and
rinse aid will not be dispensed even if the relative compartments contain
them. If the containers are empty, the lights will remain on.
If the option is not provided, we recommend the use of conventional
products (separate detergent, salt and rinse aid), because with
conventional washing cycles, combined products might create problems
such as a white deposit, poor drying results and residues left on dishes.
For further information, refer to the detergent pack.
IMPORTANT:
when no longer required, the optionmust be deactivated by pressing the
relative button (the light goes out).
These products
are not suitable
for use with
excessively “hard”
water.
If the hardness level set is higher than H3, when the option is activated
the relative light flashes to indicate that the product is being used
incorrectly; the dishwasher will still work, but washing results may be
poor.

TO SAVE ON ENERGY! … AND PROTECT THE ENVIRONMENT
Always use the dishwasher with a full load.
Do not wash the dishes in running water.
Use the washing program that is most appropriate for each type of
load.
Do not carry out any preliminary rinsing.
If available, connect the dishwasher to a hot water supply up to 60°C.
TO CUT DOWN ON DETERGENT CONSUMPTION! … AND PROTECT
THE ENVIRONMENT
The phosphates contained in dishwasher detergents are harmful to the
environment. To avoid using excessive amounts of detergent and to save
on electricity, observe the following:
separate the more delicate items from dishes that are more resistant
to aggressive detergents and high temperatures;
do not pour the detergent directly on the dishes.
If the door has to be opened while washingis in progress, theprogram will
be interrupted. The relative light will keep flashing and a beeper will signal
that the cycle has not been completed. You must wait about 1 minute
before closing the door to restart the program. When the door is closed
the program will continue from where it was interrupted. This operation
should only be carried out if strictly necessary, because it might cause
problems in execution of the program.
SWITCHING OFF
At the end of the program the beeper sounds
briefly and the lights of programs no. 4and 5
(marked "end") flash.
To switchoff thedishwasher, open thedoor andpress the
ON/OFF
button
(1).
ENERGY MANAGEMENT
After 5 minutes of waiting (washing cycle completed, stopped or set but
not started) the dishwasher switches to a standby state to reduce energy
consumption.
In this state, the dishwasher indicator panel (lights or display depending
on model) functions more slowly (switch-on once every 5 seconds).
REMOVING THE DISHES
At the end of the washing program, wait at least 20 minutes before
removing the dishes, to allow them to cool. To ensure that any drops of
water left in the top basket cannot drip onto the dishes still in the bottom
basket, you are advised always to empty the bottom basket first.

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.
The dishwasher is factory set for water
hardness level 3 (average hardness 41-
60°dF – 24-31°dH).
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 thesemodels, the cap of
the salt container contains a green float which descends as the salt
concentration in the water drps. 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 ofthis occurring, thewarranty
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
17
Donot use table salt as it contains insoluble substanceswhich, 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 SOFTENING SYSTEM
The dishwasher is equipped with a device which allows the softener
setting to be varied to suit the hardness of the mains water. The hardness
is set using the PROGRAM SELECTION BUTTON (3).
To access the setting function, hold the button down for more than 15
seconds. The WATER HARDNESS ADJUSTMENT INDICATOR LIGHT
(4) flashes, while the SELECTED PROGRAM INDICATOR LIGHTS (2)
show the current setting. Each pressure on the button changes the
setting following the sequence in the table below:

Contact your local water board for information on the hardness of your
water supply.
After adjustment or display of the current setting, simply do not touch the
button for a few seconds; the dishwasher will automatically return to
standard mode, quitting the adjustment 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 ontheleft, andtherinse
aid dispenser is on the right.
With the exception of the SOAK program, before everywashing 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
19
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 door.
Rotate the container cap anticlockwise by ¼ of a turn and remove it.
Add therinse aiduntil thecontainer isfull (approximately 140 cc). The
optical level indicator on the side of the cap should be completely
obscured. Refill the rinse aidwhen theoptical level indicator becomes
clear again, or when the rinse aid warning light illuminates.
Replace the cover and turn it in a clockwise direction.
Use a cloth to remove any spillage of rinse aid which might lead to
the formation of excess foam.
ADJUSTING THE RINSE AID DISPENSER SETTING
The dishwasher is factory set for medium water hardness. However it
possible to change the setting by turning the dispenser’s selector to the
desired position: the amount of rinse aid dispensed is proportional to the
selector position.
To adjust the rinse aid setting, rotate the dispenser cap through a
quarter turn in an anticlockwise direction and remove it.
Then use a screwdriver to rotate the rinse aid selector to the desired
position.
Replace the cap, turning it clockwise.
The amount of rinse aid must be increased if the washed dishes
appear dull or feature circular stains.
If, on the other hand, the dishes are sticky or have white streaks, it is
necessary to reduce the rinse aid setting.

User instructions
20
ADDING THE DETERGENT
To open the detergent dispenser cap, lightly press the
button P. Add the detergent and close the cap
carefully.
During the washing cycle, the dispenser will be
opened automatically.
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. For optimal
washing results it is important to use a good quality detergent.
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 usedetergentsformulatedfor washing dishesby hand,because
they produce a great deal of foam and may negatively affect the
operation of the dishwasher.
Add the correct amount of detergent. An insufficient amount of
detergent willresult ina partialremovalof dirt fromthe dishes, whereas
an excessive amount is wasteful and does not improve the washing
results.
The market offers liquid and powder detergents with differing chemical
compositions, which may contain phosphates, or be phosphate-free
but contain natural enzymes.
- Detergents containing phosphates are more effective against grease
and starch at temperatures above 60°C.
- Enzyme detergents, on the other hand, are also effective at lower
temperatures (from 40 to 55°C) andaremore easily biodegradable.
With enzyme detergents it is possible to obtain at low temperatures
comparable results to those which can only be achieved at 65°C
using traditional detergents.
For the safeguarding of the environment we recommend the use of
phosphate- and chlorine free detergents.
