- Errors 01, 05, 09, 10, 12 are critical (button 7 is fixed red) and shut down the machine
completely. To reinstate the machine, request technical assistance. To reset these errors, the
PCB must be switched off and then on again (ON-OFF button 1).
- With errors 02, 03, 04, 06, 07 and 08 button 7 continues to blink red until the error is reset
(press button 3). If the problem persists, request technical assistance.
- With error 13 the machine goes to the first installation sequence. It is necessary to request
the assistance of a technician who must enter the machine model code.
7. AUTOMATIC WATER SOFTENER (OPTIONAL)
Optional automatic water softener is available for both machines with electromechanical
buttons and those with electronic control panel (with LCD display). The dishwasher is fitted
with an automatic water softener whose operation is managed directly by the PCB.
7.1 Operation
During the first loading, and at each wash cycle, the water entering passes through the water
softener reservoir containing ion exchange resins. These combine with calcium and magnesium
ions, responsible for limescale residues, and make them inert.
Due to gradual saturation the action of the resins tends to weaken over time but can be
restored thanks to the addition of saline water. This process is called "regeneration".
Therefore the water softener also has a 1 kg capacity salt container, which must be periodically
filled. A sensor checks the salt level and, if insufficient, the message "SALT FINISHED!" is
displayed followed by an alarm sound, or the warning light comes on (8 for version with
electromechanical buttons.

From this stage on, even if the dishwasher is able to operate, the water softener is not treating
the water. Due to the action of the water softener, the hardness of the water used for the
wash cycles is reduced to about 6-8 °f. To maintain the effectiveness of the resins and to
keep the water hardness level constant, the dishwasher carries out a regeneration after a
number of wash cycles, established according to the initial water hardness settings(see Table
1). Regeneration lasts 120 seconds and is done at the end of each initial filling and during the
wash cycle with the chosen interval.
If a wash cycle with a shorter time has been set, during regeneration this will last 120sec +
20sec (rinse); during the 120 seconds, for all the additional time due to regeneration, the
display will show the message "SELF REGENERAT".
SELF REGENERAT.
7.2 Installation
The dishwasher with automatic water softener comes with the water softening function
already activated and set for a hardness of 25 °f.
For this value, regeneration of the resins occurs every 20 cycles in the electromechanical
version and 24 cycles in the electronic version. For different hardness values, the frequency of
regeneration must be changed as indicated in Table 1. To change the regeneration frequency,
request technical assistance. Initial filling of salt in the container: unscrew the cap, fill the
container with 2 glasses of hot water, then add 1 kg of kitchen rock salt. Tighten the cap,
making sure to remove any residual salt on the outside.
7.3 Maintenance
Maintenance of the automatic water softener system consists of filling the salt
container whenever the message "SALT FINISHED!" appears on the LCD display, or
when the indicator light comes on (in versions with electromechanical buttons).
Only use kitchen rock salt: unscrew the cap inside the wash tank and carefully add 1 kg of
salt, using the special funnel provided and facilitating the outflow of water contained in the
reservoir below.
Make sure the salt does not spill, and do not exceed the recommended amount. After adding
the salt, add 2 glasses of hot water in order to facilitate the dissolving of salt, clean the gasket,
close the cap properly, eliminate any residual salt, remove the overflow pipe, if present and
rinse the tank thoroughly.
Residual salt that is not removed can cause corrosion of the steel!
