9.4 DISHWASHER WITH INCORPORATED CONTINUOUS WATER SOFTENER
Dishwashers with incorporated continuous water softener have a continuous softener in the water circuit. By
means of special resins, this device removes the calcareous substances from the feed water, supplying decal-
cified water for washing.
To activate the continuous water softener, set the parameter
For the continuous softener to work properly the resins must be regenerated periodically with a frequency
depending on the hardness of the inlet water, the number of wash cycles carried out and the max. hardness
set with the parameter
Unlike conventional water softeners, this continuous softener does not require machine stops for regenerating
the resins.
To regenerate the resins it is necessary to put coarse salt in the special container located in the dishwasher.
In particular, the salt container must be filled when the dishwasher is started the first time and whenever the

Use only coarse salt with a NaCl purity grade of 99.8 %. The use of salt with a lower purity grade may
cause the sale container filter to clog and the water softener to malfunction.

If the parameter SrU is set to the value10, according to the factory setting, the water softener outlet water
hardness can vary between 3°f - 10 °f / 1.7 °d - 5.6 °d / 2.1 °e - 7 °e.

NB: To save the new water hardness value, in addition to the normal parameter modification and saving oper-
ations it is necessary to disconnect and reconnect the machine's main power supply by means of the main
switch on the external board.
Water softener operation can be checked by forcing the regeneration of resins, without waiting for the outlet
