Wat er s of t eni ng syst em / spec i al sal t
To ensure good rinsing results, the 
dishwasher requires soft water, i.e. 
water which is low in lime, otherwise 
limescale will be deposited on the 
utensils and interior container. Tap 
water above 7° dH (1.2 mmol/l) 
must be softened. The water 
is softened with special salt 
(regeneration salt) in the water 
softening system of the dishwasher. 
The setting and therefore the 
required amount of salt depends on 
the degree of hardness of your tap 
water (see following water hardness 
table).
* optional feature which may or may 
not be included with your 
dishwasher.
