I8 Hood type dishwasher with incorporated
continuous water softener
These models have a continuous softener in the
dishwasher water circuit. By means of special resins,
this device removes the calcareous substances from
the feed water, supplying decalcified water for
washing.
For the continuous softener to work properly the resins
must be regenerated periodically, with frequency
depending on the hardness of the water and the num-
ber of wash cycles carried out.
Unlike conventional water softeners, this continuous
softener does not require machine stops for regenera-
ting the resins.
Cause / Solution
Check that the cock is open.
Check that the water inlet filter is
clean.
Check the minimum mains
pressure.
Check that the overflow pipe is
inserted.
Check if the overflow has been
removed.
Check for obstruction on the
waste outlet pipe and the
overflow aperture.
Check for obstruction on the
waste outlet pipe and the
overflow aperture.
The appliance continues to
operate, but appropriate checks

recommended.

99.8% NaCl. The use of salt with a lower
purity level can cause clogging of the salt
container filter and malfunctioning of the
water softener.
When the salt container is empty, the message
