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 such cases, the regeneration prolongs the total
duration of a programme by additional 5 minutes.
Subsequently, the rinsing of the water softener that
lasts 5 minutes may begin in the same cycle or at
the beginning of the next programme. This activity
increases the total water consumption of a
programme by additional 4 litres and the total
energy consumption of a programme by additional
2 Wh. The rinsing of the softener ends with a
complete drain.
