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.
Each performed softener rinse (possible more
than one in the same cycle) may prolong the
programme duration by another 5 minutes
when it occurs at any point at the beginning
or in the middle of a programme.
All the consumption values mentioned in
this section are determined in line with
the currently applicable standard in
laboratory conditions with water hardness
2.5mmol/L (water softener: level 3)
according to the regulation: 2019/2022 /
UK Ecodesign 2021/745.
The pressure and the temperature of
water as well as the variations of the
mains supply can change the values.
