4. Operating instructions

Once the dishwasher has been correctly installed, prepare for use as

follows:

x Adjust the water softening system;

x Add the regenerating salt;

x 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 41-60°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.

The salt reservoir is in the bottom of the dishwasher. After removing the

basket, undo the cap of the reservoir by turning it anticlockwise and pour

the salt in using the funnel supplied with the dishwasher. Remove any

salt residues around the opening before screwing the cap back on.

x 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.

x 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.

x Only use regenerating salt specially formulated for domestic

dishwashers. If using salt tablets, do not fill the container

completely.
