 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. 
•  Open the door S.  
•  Add the rinse aid until the container 
is full (approximately 140 cc). 
 
 
•  The optical level indicator O 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. 
•  Close the door S. 
•  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. 
 
   
  
 • 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.

ADDING THE DETERGENT 
After adding the detergent, to close the lid slide it in the direction shown 
by the arrow as far as it will go then press gently to lock. During washing, 
the dispenser will be opened automatically. 
   
      
 
 
  
 • 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 use detergents formulated for washing dishes by 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 will result in a partial removal of dirt from the 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) and are more 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.

 • 3/1 Products 
If you wish to use detergents which already contain salt and rinse 
aid, check whether your dishwasher is fitted with the 3/1 option 
button on the Controls description page and then refer to the 
section which explains how to use this function. 
If the button is not provided, we recommend the use of conventional 
products (separate detergent, salt and rinse aid), because with 
conventional washing cycles 3/1 products might create problems 
such as a white deposit, poor drying results and residues left on 
dishes.   
 
 
 
 The introduction of detergent into the rinse aid dispenser, even in 
liquid form, will damage the dishwasher.  
 
 
 
 
4.3 General warnings and recommendations 
 
 
 
 Before using the dishwasher for the first time, it is advisable to read the 
following recommendations concerning dish types to be washed and 
their loading. 
There are generally no constraints on the washing of domestic dishes, 
but in certain cases it is necessary to take their characteristics into 
account.  Before loading the dishes into the baskets it is necessary to: 
• remove coarse food remains: e.g. bones, fish-bones, etc. which 
may clog the filter or damage the wash pump. 
• soak pots and pans with burnt food residues in the bottom for 
easier removal.   There is no need to pre-wash the dishes under running water before 
loading them into the baskets since this only wastes water.   Correct loading of the dishes helps ensure optimal washing 
results.

 WARNING!  • Make sure that the dishes are securely in place so that they cannot 
tip over or obstruct the rotation of the spray arms during the 
washing cycle. 
• Do not place very small objects in the baskets as these could fall 
and obstruct the spray arms or the wash pump. 
• Containers such as cups, bowls, glasses and pots should always 
be loaded with the opening facing downwards and with any cavities 
at an angle, to allow the water to drain out. 
• Do not stack dishes or place them in such a way that they cover 
one other. 
• Do not place glasses too close together because they may knock 
against each other and break, or there might be staining at the 
point where they touch. 
• When using detergent tablet, take care not to place large pans or 
dishes in the zone underneath the detergent dispenser, since the 
tablet might fall onto the dishes and fail to dissolve completely.  MAKE SURE that the items being washed are dishwasher-safe.  Items which are not dishwasher-safe:  • Wooden dishes, pots or pans: these may be damaged by the 
high washing temperatures. 
• Handcrafted items: these are rarely suitable for washing in a 
dishwasher. The relatively high water temperatures and the 
detergents used may damage them. 
• Plastic dishes: heat resistant plastic dishes must be washed in the 
upper basket. 
• Dishes and objects in copper, tin, zinc or brass: these tend to 
stain. 
• Aluminium dishes: items made from anodised aluminium may 
lose their colour. 
• Silverware: silver items may stain. 
• Glass and crystal: in general, glass and crystal objects can be 
washed in the dishwasher. However, certain types of glass and 
crystal may become dull and lose their clearness after many 
washings. Therefore, for these items we recommend using the 
least aggressive program available. 
• Decorated items: the decorated objects available on the market 
are generally able to withstand washing in the dishwasher, 
although the colours may fade after a great many washes. If in 
doubt as to the fastness of the colours, it is advisable to wash just a 
few items at a time for approximately one month.

5.  Cleaning and maintenance  
 
Before carrying out any work, always disconnect the appliance 
from the electrical power supply. 
 
 
5.1 General warnings and recommendations   Avoid the use of acidic or abrasive detergents.  Clean the outer surfaces and door-lining of the dishwasher regularly 
using a soft cloth moistened with water or with a normal detergent 
suitable for painted surfaces. Clean the door gaskets with a damp 
sponge. Periodically (once or twice a year) it is advisable to clean the 
tank and gaskets, using a soft cloth and water to remove any deposits. 
 
 
CLEANING THE WATER INTAKE FILTER 
The water intake filter A located at the outlet of the water supply tap 
needs to be cleaned periodically. 
After having closed the water supply tap, unscrew the end of the water 
intake hose, remove the filter A and clean it delicately under running 
water. Reassemble filter A in its seat and carefully screw the water 
intake hose back into position. 
 
 
 
 
 CLEANING THE SPRAY ARMS 
The spray arms can be easily removed for periodic cleaning of the 
nozzles, to prevent possible clogging. Wash them under running water 
and carefully replace them in their seats, checking that their rotary 
movement is in no way impeded. 
 To remove the orbital spray arm assembly, take hold of the longer arm 
and pull the orbital unit upward. Wash the arms under a jet of running 
water and return them carefully to their seat. After reassembly, check 
that the spray arms turn freely. Otherwise, check that they have been 
installed correctly.

 CLEANING THE FILTER UNIT  •  It is advisable to periodically inspect the centre filter C and, if 
necessary, to clean it. To remove the filter, grip the tabs, turn them  
anticlockwise and lift upwards; 
•  push the centre filter D from the underside to remove it from the 
micro-filter: 
•  separate the two parts which make up the plastic filter by pressing 
the body of the filter in the zone shown by the arrows; 
•  remove the centre filter by lifting it upwards.
