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 decalcified water for washing.
To activate the continuous water softener, set the parameter
water softener board is connected to the LK485 board.
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
SER (in the HCP family) to the value 9 or the value 11 if the
SrU (in the
CFG family).
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 used for the first time and whenever the messages
SAL 0 or SAL END are displayed at the start or end of a wash cycle. The salt container holds up to 1.5 kg of salt.
CAUTION: 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.
IMPORTANT: The messages
salt, as the salt must circulate in the entire system. Correct operation of the dishwasher is not, however, affected.
The number of regeneration cycles performed can be checked by consulting the parameter
counters.
nrE only counts regeneration cycles carried out with the salt container adequately filled; there is another counter, rES (in the
Cnt family) that indicates the number of regeneration cycles done without salt.

AUTONOMY OF A COLUMN OF RESINS ACCORDING TO THE CHANGE IN INLET WATER HARDNESS, WITH OUTLET
WATER HARDNESS OF 10 °fH / 5.6 °dH /7 °cH (
Maximum outlet water hardness can be modified by setting the SrU value. The outlet water hardness can be modified from the
value of 4° fH to 14° fH.
NB: To save the new water hardness value, in addition to the normal parameter modification and saving operations 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 water hardness to
reach the set max. value (
To do this, wait for the water softener to finish previous resin washing or regeneration operations and set the parameter FrG
(CFG family) to 1 for regenerating column A or to 2 for regenerating column B.
Switch the machine off and on again so that it carries out complete regeneration of the set column. If previous resin washing or
regeneration operations were not completed, the manual request for regeneration is not carried out.
It is possible to check which column is being used for boiler filling by querying the parameter AAC (ron family): if AAC = 0
column “A” is used, if AAC =1 column “B” is used.
The number of litres used by the machine can be checked by querying the parameters nnc (m3 ) and L (litres). To calculate the
total number of litres used by the machine, add the nnc and L values.
NB: In machines with incorporated continuous water softener, tank filling cannot be carried out through overflowing (btF=0) but
only by means of successive rinse cycles (btF=75). Therefore the btF parameter must be set to 75.
SrU is set to the value10, according to the factory setting, the water softener outlet water hardness can
