3. 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.
3.1 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 41-60°dF – 24-31°dH).
When using water of medium hardness, the regenerating salt container should be refilled after
approximately 20 washing cycles. The salt container can hold approximately 1.5 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. If using salt tablets,
do not fill the container completely.
• Do not use table salt as it contains insoluble substances which, over time, may damage the
water softening system.
• When necessary, refill the regenerating salt container before starting the washing program.
In this way, the excess saline solution will be immediately removed by the water; the prolonged
presence of salt water inside the tank may lead to corrosion.
Be careful not to confuse the salt and detergent packages; adding detergent to the salt
container will damage the water softening system.
