Flexi Tabs
Ideal for multi-function detergents, this option allows washing to be
optimised, with full benefits from the combined-action tablets. When this
option is activated, any salt and rinse aid in the relative containers will
not be used.
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.

HYCLEAN
The "HYCLEAN" option 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 the program (e.g. because the door is opened or due to a
power blackout), the light of the option and the program lights 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
and reduces the program duration. Place dishes in both baskets then
load the detergent dispenser than less than the normal amount for a full
load.
TO SAVE ON ENERGY! … AND PROTECT THE ENVIRONMENT
•Always try to run the dishwasher fully loaded.
•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.
REMOVING THE DISHES
At the end of the washing program, wait at least 20 minutes before
removing the dishes, to allow them to cool down. To prevent any water
droplets on the upper basket from falling on the dishes in the lower
basket, it is advisable to unload the lower basket first, and then the
upper basket.

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. 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 the regeneration system. In the event of this occurring, 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
16
•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 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 (2).
To access the setting function, hold the button down for more than 15
seconds. The WATER HARDNESS ADJUSTMENT INDICATOR LIGHT
(6) flashes, while the SELECTED PROGRAM INDICATOR LIGHTS (4)
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 on the left, and the
rinse 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
18
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 the rinse aid until the container is full (approximately 140 cc).
The optical level indicator on the side of the cap should be
completely obscured. Refill the rinse aid when the optical 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.
