Water softener
• The hardness of the water varies from place to place. If hard water is used in the
dishwasher, deposits will form on the dishes and utensils.
• The appliance is equipped with a special softener that uses a salt container specifically
designed to eliminate lime and minerals from the water.
Adjusting salt consumption
The dishwasher is designed to allow for adjustment in the amount of salt consumed based on
the hardness of the water used. This is intended to optimise and customise the level of salt
consumption. The dishwasher must be adjusted to the water hardness in your area (contact your
local water board for information). This will affect the consumption of dishwasher salt consumed.
The factory setting is H3.
