The order of the basic settings presented in the
table is also the order of the settings in setting
mode.
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.
