7.2 The water softener
The water softener removes minerals from
the water supply, which would have a
negative effect on the washing results and on
the appliance.
The higher the content of these minerals, the
harder your water is. Water hardness is
measured in equivalent scales.

Do not use salt at this level.
Regardless of the type of detergent used,
set the proper water hardness level to
keep the salt refill indicator active.
Multi-tabs containing salt are not effective
enough to soften hard water.
Regeneration process
For the correct water softener operation, the
resin of the softener device needs to be
regenerated regularly. This process is
automatic and is the part of the normal
dishwasher operation.
When the prescribed quantity of water (see
values in the table) has been used since the
previous regeneration process, a new

The water softener should be adjusted
according to the hardness of the water in your
area. Your local water authority can advise
you on the hardness of the water in your
area. Set the right level of the water softener
to assure good washing results.
