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.
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. It is important to set the right level of the
water softener to assure good washing results.

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.
