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.
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:
UK Ecodesign 2021/745.
The pressure and the
temperature of water as well
as the variations of the
mains supply can change
the values.
