The Incanto machines are the first machines that have installed the new filter AquaClean. They
were created to accommodate both new and the old filter, mounting the water container code
17001363-996530073476. From S.N. TW901539488484 the Incanto machines will mount a new
water container that can only accommodate the new filter (the assy code is visible on exploded view
of reference).
The SAECO AquaClean water filter purifies the water your machines uses for brewing coffee. This results in
a greater coffee taste. Moreover it prevents mineral deposits in the water to build up, which eliminates the
need of descaling your machine for 500000ml of water. We recommend installing the water filter AquaClean
the first use of the machine to the maximum before using 5000 ml of water.
After a period of uses the machine, the display will indicate when the filter needs to be replaced, the maxi -
mum limit equivalent to 62500ml.
In this way you can replace the filter 8 times without the need for descaling. This equals approx. 500000ml
of water. When Aquaclean filter is activated the display will show an icon indicating the percentage of use
(initially 100%).
The conditions related to the filter work environment, water, therefore, an active environment for bacteria
and microorganisms, require the replacement with a minimum frequency. The filter, indeed, is activated and
starts working from the time is filled with water and continues working even with the machine off.
3 months from the activation is the correct replacement frequency to ensure the best performance and the
proper operation.
The filter can not be deactivated manually, as it must end its life cycle.
The filter symbol flashes slowly when the autonomy of the current filter becomes less 8050ml (percentage
shown on the display 10%). When the autonomy of the current filter becomes less than 2000ml (percentage
shown on display 0%) the icon flashes quickly. After a maximum of 62500ml of water supplied the flashing
light turn off. Because you did not activate a new filter, the machine will show that after a while’ you need to
start descaling. After the flashing light goes out is calculated:
(for example) After using 1 filter, the TH reduces of 1/8. With Water hardness 4 and brewing just coffee/water
products the TH is set to 30 liters. 30 liter minus 1/8 is 26,25 liters. The first filter expires at 62,5liters - > the
warning “DESCALE” should appear at 26,25+62,5 = 88,75 liters from start.
If the consumer is using the AquaClean filter, and replaces it when indicated by the machine. The machine
needs to be descaled after 8 filter replacements. When the 8th filter needs to be replaced the machine will
inform you need to descale before placing a new filter.
Note: the quantities of water, for each cycle of the filters, are not affected by the hardness of the water itself.
The machines : Intelia Evo2 , Granbaristo V2 , Exprelia V2 , New Incanto e Cattiva will mount a water con -
tainer can only mount the filter Aquaclean and will not be able to mount the old.
“Water low” message (water reserve)
Function:
The water level is monitored by a capacitative sensor, located one third of
the way up the water tank wall.
If the electronics assembly detects, by means of the sensor, that the amount
of water in the tank has dropped below the above mentioned level, a water
reserve remains available for the dispensing process underway (this will
cover 200 flow meter pulses).
The product dispensing process will then come to an end.
If a dispensing cycle ends after the sensor has been triggered (in the
reserve) then the display “Water low” continues to be displayed during the
following dispensing cycle.
