8.2 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. Set the right level of the water softener
to assure good washing results.
