[. . . ] END OF CYCLE At the end of the washing cycle the dishwasher gives a short acustic signal and the program indicators nr 4 and 5 start blinking (the word "end" is displayed on the window). To switch off the dishwasher, open the door and press the ON/OFF button (1). 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. 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. 4. 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 41-60dF 24-31dH). SALT When using water of medium hardness, the regenerating salt container should be refilled after approximately 20 washing cycles. 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. If, on the other hand, the dishes are sticky or have white streaks, it is necessary to reduce the rinse aid setting. 19 User instructions ADDING THE DETERGENT To open the detergent dispenser cap, lightly press the button P. During the washing cycle, the dispenser will be opened automatically. When a program with hot prewash is selected (see program table), extra detergent must be placed in the cavity G/H (depending on models). 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. 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. 20 User instructions 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 60C. - Enzyme detergents, on the other hand, are also effective at lower temperatures (from 40 to 55C) 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 65C using traditional detergents. For the safeguarding of the environment we recommend the use of phosphate- and chlorine free detergents. [. . . ] Water temperature monitoring malfunction Interrupt the program and switch off the dishwasher. Switch the dishwasher back on, program it again and start the washing cycle. Water intake malfunction The appliance does not take in water or does not do so correctly. Check that the water connections are correct, the water intake tap is turned on and the filter is not fouled. [. . . ]
