If you do use combination detergents, add salt and rinse aid to the
dishwasher. Then adjust the water hardness setting and rinse aid
setting to the minimum. When you then use separate detergents
again, you should fill the salt and rinse aid compartments, adjust the
water hardness setting to the maximum and run an empty wash, then
adjust the water hardness setting and the rinse aid setting to the
appropriate level.

To ensure the best efficiency, the dishwasher needs soft water. Hard
water means that lime residues remain on the dishes and the interior
of the dishwasher, affecting performance. The softener system is
designed to remove the ions that make the water hard to provide the
best quality wash performance. This is achieved by using dishwasher
salt.
