We advise you to carefully read all the instructions contained in this manual, in order to understand how to operate your dishwasher safely and correctly. [. . . ] The salt container can hold approximately 1. 7 Kg of salt in grains. Some models are equipped with an optical no-salt indicator. In these models, the cap of the salt container contains a green float which descends as the salt concentration in the water drops. When the green float can no longer be seen through the transparent cap, the container must be topped up with regenerating salt. The container is situated at the bottom of the dishwasher. 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. The mixture of water and detergent must never penetrate the salt container, as this would compromise the operation of the regeneration system. In the event of this occurring, the warranty will be invalidated. Only use regenerating salt specially formulated for domestic 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. 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. Also available are tablet detergents which state that that no salt or rinse aid is required. [. . . ] After reassembly, check that the spray arms turn freely. Otherwise, check that they have been installed correctly. 38 User instructions CLEANING THE FILTER UNIT It is advisable to periodically inspect the centre filter C and, if necessary, to clean it.
