connection or the hose.

2. Installation and hook-up

Remove the polystyrene basket retainers.
Position the appliance in the desired place of installation. The back or
sides of the dishwasher may be placed up against walls or other furniture
units. If the dishwasher is installed near a heat source, fit the special
insulating panel to prevent overheating and malfunction of the appliance.
To ensure stability, install integrated or built-under dishwashers only under
continuous worktops, and screw them to the adjacent units. To facilitate
the installation procedure, the intake and drain hoses can be positioned in
any direction; make sure that the hoses are not kinked, crushed or pulled
too tightly. Make sure to tighten the locking ring-nut once the pipes have
been placed in the direction required. A hole at least 8 cm in diameter is
required to allow the power supply cable and pipes to pass. Before putting
the dishwasher into its definitive position, turn on the water tap and check
that there are no leaks from the tap connection, the dishwasher

Level the appliance on the floor using its adjustable feet. This operation is
essential for ensuring correct operation of the dishwasher.

Some models are equipped with only one adjustable foot at the rear, which
can be adjusted by turning the screw on the lower front part of the
appliance.

Building-in a dishwasher underneath a hob is absolutely forbidden.
Moreover, dishwashers may not be installed directly touching appliances

which are not conventional built-in kitchen appliances (e.g. fireplaces,
stoves, etc.).

When installing the dishwasher in a compartment next to one or more other
appliances, it is essential to comply with all the recommendations provided
by the appliance’s manufacturer (minimum distances, installation
procedures, etc.).

For free-standing models only:

- Installing a hob on top of a free-standing dishwasher is absolutely
forbidden.

- If the appliance is not built-in and is therefore accessible on one side, the
door hinge area must be covered for safety

reasons (injury hazard). The covering fixtures are available as an accessory

from specialist dealers or the After-Sales

Service.

- To build in the dishwasher, the special kit must be purchased from authorised

dealers or the After-Sales Service.

2.1 Water supply connection

Preventing the risk of clogging or damage: if the water pipe is new or

has not been used for a long time, before connecting to the water supply
check that the water is clear and free of impurities, to prevent damage to
the appliance.

The dishwasher must always be connected to the water system with
new hoses; old or used hoses must never be reused.

Connect the intake hose to a cold water supply with ¾” gas
thread, inserting the filter A supplied with the dishwasher.

Take care to screw the hose firmly into place with your
hands and then complete by tightening about ¼ of a
turn with pliers.

In dishwashers equipped with the ACQUASTOP device,
the filters is already fitted inside the threaded ring.

The dishwasher can also be connected to a hot water supply
60°C. Supplying the appliance with hot water cuts down the washing time
by approximately 20 minutes, but slightly reduces its effectiveness. Make
the connection to the domestic hot water supply using the same procedure

Insert the dishwasher’s drain hose
into a drain pipe having a diameter
of at least 4 cm, or alternatively,
place it inside the kitchen sink
using the plastic support provided,
taking care not to crush or
excessively bend the hose. It is
important to prevent the hose from
coming loose and falling. For this
purpose, the plastic support is
equipped with a hole for tying it to
the wall or water tap.

The free end should be positioned at a height of between
and should never be submerged in water. If a horizontal drain extension
hose is used (for a maximum of 3 m) the drain hose can be placed at a

3.2 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.

It activates automatically when a program that includes the function it is
selected (the light comes on).

It can be deactivated b pressing the button (the light turns off).
The program ends with a drying cycle that consists of a time during which the door is
closed, and a time during which the door is slightly open (just waiting, to assist drying).
The duration depends on the program and model.
Any intervention (opening / closing the door, switching off etc.) during this stage will
end the program early.
The program can be interrupted during the drying cycle and the dishwasher can
unloaded before the cycle has completely ended, which is indicated by a visual and/or
audible alarm (depending on the model), but best drying results may not be obtained.

The complete program ends only when indicated by a visual and/or audible

door must not be forced open and closed before the wash cycle has
ended completely.
