REGENERATION PROCEDURE:
1.
Load a certain amount of water (approx. 90cc), activating the solenoid valves (fill and regeneration)
in order to direct the flow through the salt, thus flushing brine through the resins. Then shut the
solenoid valves.
2.
Wait about 10 minutes.
3.
Load a second amount of water (about 190cc), in the same way.
4.
Wait 5 minutes.
5.
The next step is to wash the resins, flushing between 1 and 2 litres of water over them, activating only
the fill solenoid valve and not the regeneration solenoid valve.
6.
Final draining.
Important: It is important to bear in mind that each time the Main PCB is replaced, the litre count
for management of water hardness setting is lost, and must therefore be reset.
Water softening may be less than optimal for another few cycles.
Drying phase:
The drying system operates on the same principle as that on EVO 3 dishwashers. In the last phase, the
appliance runs a hot rinse, activating the wash element. The water will reach a high temperature, which
will depend on the programme chosen, for example it will reach 70°C for certain programmes but will not
exceed 64°C with the “Baby Cycle”.
Next, a certain period of time is allowed to pass with water in the tank so that the crockery drains and the
steam condenses on the walls. The liquid rinse aid (that placed in the rinse aid dispenser by the user),
plays an important part in drying performance, helping water to “run-off” dishes.
The drying phase includes a certain period of time with no water in the tank.
Note.: Excellent washing and drying results can be obtained by using powder detergent and liquid
rinse aid.
“Extra Dry” Option:
Free Standing appliances with led interface may also feature the “Extra Dry” option”. Choosing this option
extends the duration of the drying phase with no water in the tank by 10-20 minutes (depending on the
programme selected).
Nonetheless, the drying temperature remains unchanged.
Blocked Filters:
If the filters become clogged or the user inserts a pot facing upwards, the Pressure Switch may signal
empty.
In this case, in the Evo 3 platform the dishwasher proceeded to “Filter Cleaning”; in this platform no such
routine is present, so the appliance will load water until the pressure switch signals full again or until
5.5 litres of water have been loaded. In this case (5.5 Litres loaded) the dishwasher will drain and proceed
to the next wash step. In the event of chronically clogged filters, the user may call to report crockery still
being dirty at the end of a wash cycle.
Advice for the Call Center:
1.
wash the filters
2.
Position pots upside down and try washing again
