B4 DETERGENT/RINSE-AID DISPENSERS AND
SETTINGS
If the appliance is connected to a water softener or
osmotic device, contact the detergent supplier for a
specific product.
Peristaltic dispensers (rinse-aid and detergent) require
periodic maintenance. The internal hose of the rinse-
aid dispenser should undergo periodic maintenance
(at least once or twice a year).
1. Dishwasher with incorporated detergent dis-
penser pump (Fig. 12).
Pump “R” dispenses about 0.9 g/s of detergent. When
the appliance is filled with water for the first time in the
day, it dispenses about 86 g of detergent in 90 sec.,
thereby providing a concentration of 2 g/l. Pump “R”
dispenses about 8 g in 8 sec. at each cycle.
Dispenser operating time may be changed, following
the instructions given in the next paragraph.
Insert the hose provided in the kit into the detergent
container.
2. Dishwashers with incorporated peristaltic
rinse-aid dispenser pump (Fig. 12).
Pump “S” dispenses about 0.1 g/s of rinse-aid. It dis-
penses 0.4 g in 4 sec. at each rinse.
Dispenser operating time may be changed, following
the instructions given in the next paragraph.
Insert the hose provided in the kit into the rinse-aid
container.
3. Dishwashers with incorporated rinse-aid dia-
phragm dispenser pump (Fig. 12).
Pump “T” is installed in appliances with pressure
boiler.
Dispensed amounts may be changed according to the
instructions given in the paragraph below.
Insert the supplied hose into the rinse-aid container.
Connections for automatic detergent dispenser
(Fig. 12)
Fig. 12
There are two holes (plugged) “O” (Ø 5 mm) for intro-
ducing the detergent.
These holes may be easily identified from outside by
looking for the countersunk marks on the external
panel.
Inside the tank there is a hole “P” (Ø 10 mm) closed
with a plug, which may be used for mounting a liquid
detergent injector.
Electrical connections for automatic detergent and
rinse-aid dispensers
Terminals are available on the power supply terminal
board for the electrical connection of external dispens-
ers working at 220…240 V. Max. power 30 VA.

 the dispenser is not activated during filling of
the tank.
 the dispenser is activated during wash
pump operation and, thanks to the concentration
measured by the conduction sensor, the correct
amount of detergent is dispensed.
2) Rinse-aid diaphragm dispenser
To change the dispensed amount, turn on screw
“D” accordingly (Fig. 12).
Suggestion: to check the effectiveness of the rinse-
aid, look at freshly washed glasses against the light.
Drops of water remaining on the glass indicate an
insufficient amount while streaks indicate an excess.
Changing the detergent/rinse-aid type
If changing to a different detergent/rinse-aid type
(even one by the same manufacturer), you must rinse
the suction and pressure hoses with fresh water before
connecting the new detergent/rinse-aid container. Oth-
erwise, the mixing of different types of detergent/rinse-
aid will cause crystallisation, which may result in a
breakdown of the dosing pump. Failure to observe this
condition will invalidate the guarantee and product lia-
bility.
B6 MAINTENANCE
• Descale the boiler, the internal surfaces of the tank
and the appliance water piping once or twice a
year.
• Descale the rinse and wash jets every month using
vinegar or a descaling agent.
• The internal hose of the rinse-aid and detergent
peristaltic dispenser should undergo periodic main-
tenance (once or twice a year).
Prolonged period of inactivity
If the dishwasher is not to be used for a long time, pro-
ceed as follows:
• Close the water supply cock.
• Completely drain the tank.
• Remove and carefully clean the filters.
• Completely drain the incorporated dispenser
hoses, removing them from the containers. Repeat
the procedure described in the paragraph “Manual
activation” at least 3 times.
• Completely drain the boiler by simultaneously
pressing the buttons as shown in the figure.
A buzzer indicates completion of drainage.
• Spread a thin film of Vaseline oil over all the stain-
less steel surfaces.
Preventive maintenance
The preventive maintenance call may be activated

Our appliances have been studied and optimised to give high performance. This appliance must be used exclusively
for the purpose for which it has been designed, i.e. for washing dishes with water and specific detergents. Any other
use is to be considered improper.
This appliance does not carry out the rinse cycle should there be no supply water; it stops all functions with an error
message “A1” (also see “Warning messages”).
TIPS
• Carry out a couple of cycles without dishes to flush out any industrial grease which has remained in the
tank and piping.
• Avoid washing decorated dishes.
• Do not allow silverware to come into contact with other metals.
• Do not allow food to dry on the dishes.
• Remove large food scraps from the dishes to prevent clogging the filters.
• Pre-wash the dishes by spraying them with cold or lukewarm water, without using any detergent.
• Use automatic dispensers for the detergent.
• If there is no automatic dispenser, pour a non-foaming detergent into the tank when the water has reached
the washing temperature.

C5 FRONT LOADING DISHWASHER WITH
INCORPORATED CONTINUOUS WATER
SOFTENER
These models have a continuous softener in the dish-
washer water circuit. By means of special resins, this
device removes the calcareous substances from the
feed water, supplying decalcified water for washing.
For the continuous softener to work properly the resins
must be regenerated periodically, with frequency
depending on the hardness of the water and the num-
ber of wash cycles carried out.
Unlike conventional water softeners, this continuous
softener does not require machine stops for regenerat-
ing the resins.
AUTONOMY OF THE FULL SALT CONTAINER
ACCORDING TO THE CHANGE IN INLET WATER
HARDNESS
Salt container
The water can only be softened if there is salt in the
special container. The salt container must be filled
when the dishwasher is started the first time and
whenever the message   appears and an
audible alarm sounds.
No salt in the container
When the salt container is empty, the message 
 appears on the display and an audible alarm
sounds. Wash cycles can be started just the same,
even if the display signals no salt; in which case the
water used for washing is not softened.
How to fill the salt container
• Switch off the dishwasher by pressing button “A”
(Fig. 15).
• Unscrew cap "A" (Fig. 23) of the salt container,
turning it anticlockwise.
Fig. 23
• Pour approx. 1.5 kg of coarse salt [NaCl] in container
"A" (an amount sufficient to fill the salt container up to
the rim) using the special funnel supplied (Fig. 24).
Fig. 24
• Remove any traces of salt from the filling hole, the
container thread and the closing cap seal.
• Refit the cap of container "A", turning it clockwise
and making sure it is tight.
The salt container always has water in it, therefore it is
normal if water comes out during filling.

The factory setting of max. outlet water hardness is 10 °f/ 5.6 °d/ 7 °e.
(*) Considering a rinse time according to the factory settings.
IMPORTANT:
Only use coarse salt with a purity level of
99.8% NaCl. The use of salt with a lower
purity level can cause clogging of the salt
container filter and malfunctioning of the
water softener.
IMPORTANT:
Open the salt container only when the mes-
sage
 is displayed. Opening the
cap when the message
  is not
displayed can cause spilling of the saline
solution and compromise correct machine
operation.

IMPORTANT:
only salt may be placed in the salt con-
tainer. Do not introduce any other chemi-
cal substances such as detergent, rinse
aid or descaling agent, since these would
inevitably damage the appliance. Such
damage invalidates any warranty and
relieves the manufacturer of all liability.
IMPORTANT:
The message 
 may appear for
several wash cycles even after topping-
up the salt, as the salt must circulate in
the entire system. Correct operation of
the dishwasher is not, however, affected.

C7 RESIDUAL RISKS
The machine has several risks that were not com-
pletely eliminated from a design standpoint or with the
installation of adequate protection devices.
Nevertheless, through this manual the Manufacturer
has taken steps to inform operators of such risks, care-
fully indicating the personal protection equipment to be
used by them.
Sufficient spaces are provided for during the machine
installation phases in order to limit these risks.
To preserve these conditions, the corridors and areas
around the machine must always be:
• kept free of obstacles (e.g. ladders, tools, contain-
ers, boxes, etc.);
• clean and dry;
• well lit.
For the Customer’s complete information, the residual
risks remaining on the machine are given below; such
actions are to be considered incorrect and therefore
strictly forbidden.
IMPORTANT:
Only introduce rinse-aid in the rinse-aid
container. Do not introduce other chemi-
cal substances such as detergent, desca-
ling agent or salt, since these would
inevitably damage the appliance. Such
damage invalidates any warranty and
relieves the Manufacturer of all liability.
