Error Messages
The dishwasher is equipped with a safety system that is able to
detect operating problems and malfunctions. These malfunctions
are signalled by the rapid blinking of one of the "M" program LEDs.
Only in the case where the indicator light for the soak cycle (see
table for cycles) blinks rapidly should you cancel the cycle as
described in the section entitled, "Changing a Cycle while
Underway". Then check to make sure that there is water in the
mains and that the tap is turned on. If the message continues,
call for technical assistance, indicating which message appeared.
If any of the other indicator lights begins to blink rapidly, turn off
the appliance and call for technical assistance, indicating which
light began to blink.
If, despite all these checks, the dishwasher still does not function
and/or the problem persists, contact the nearest authorised ser-
vice centre and provide them with the following information:
- the nature of the problem;
- the model type number (Mod...) And the
serial number (S/N...), which are indicated on the plate located
on the side of the inner part of the door.
Never call on unauthorised technicians and refuse to
allow parts to be installed that are not original spare


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.
Levelling 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 appli-
ance is level, it will help ensure proper performance.
Cold Water Connection
Connect the cold water supply hose to a threaded 3/4 (gas)
connector, making sure that it is fastened tightly in place (see fig.2).
Some models are fitted with an "Aquastop" water supply hose
(see fig.1) in which the small filter is already housed in the
threaded end.
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
Hot Water Connection
The water supply to the appliance can also be connected to the
house's hot water line (centralised system, heating system), as
long as it does not exceed a temperature of 60
In this case,the wash cycle time will be shortened by about 15
minutes and the wash efficiency slightly reduced.
The connection must be made to the hot water line following the
same procedures as those for the connection to the cold water
Anti-Flooding Protection
The dishwasher is equipped with a system that stops the supply
of water in the event of a problem with the water supply hose, or
leaks within the unit, in order to prevent damage to your home. If
for any reason the box containing the electrical components hap-
pens to get damaged, remove the plug for the appliance from
the socket immediately. In order to guarantee that the anti-flood-
ing feature operates properly, the "A" box with water supply hose
must be attached to the water supply tap as shown in Fig .1. No
other type of connection is acceptable.
The water supply hose must not, under any circumstances, be
cut, as it contains electrical parts which are live. If the length of
the hose is not adequate to make a proper connection, the hose
must be replaced with one which is long enough. This hose is
available upon request from specialised retailers and service cen-
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. Use the special plastic support that comes with the
appliance (see fig.3). The free end of the hose must be at a
height between 40 and 100 cm and must not be immersed in
The special plastic hose support must be solidly fastened to the
wall to prevent the drain hose from moving and allowing water to
spill outside the drain.
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 re-
quirement mandated by law).
If the electrical socket to which the appliance must be connected
is not appropriate for the plug, replace the plug, rather than us-
ing adaptors or the like as they could cause overheating and
The dishwasher plug must be accessible even when the appli-
ance is installed as a built-in unit so that maintenance can be
done safety.
