1) Factory setting.
2) 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 regeneration process will be
initiated between the final rinse and the
programme end.

In case of the high water softener setting,
it may occur also in the middle of the
programme, before the rinse (twice
during a programme). Regeneration
initiation has no impact on the cycle
duration, unless it occurs in the middle of
a programme or at the end of a
programme with a short drying phase. In
