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 spe- cial 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

/23.6-35 gpg). When using water of medium hardness, the regenerating salt container should be refi lled after approximately 20 washing cycles. The salt container can hold approximately 1.5 Kg (3.3 lb) of salt in grains. Some mod- els are equipped with an optical no-salt indicator. In these models, the cap of the salt container contains a green fl oat which descends as the salt concentra- tion in the water drops. When the green fl oat can no longer be seen, the con- tainer must be topped up with regenerating salt. The container is situated at the bottom of the dishwasher. After removing the lower rack, unscrew the salt container cap (ref. A fi g. 4-01) by turning it anticlockwise and pour in the salt using the funnel (ref. A fi g. 4-02) supplied with the dishwasher. Before replacing the cap (ref. A fi g. 4-01), remove any salt residues from around the opening.
