LEDs stay on for 5 seconds after which,
if no button has been pressed, they turn
off; you must then repeat the above-
mentioned procedure to turn them on
again and to prepare the electronic module
for programming;
1.
press the first button within 5 seconds
and press it again once you have obtained
the desired amount of coffee; at this
point, LEDs will turn off and this button
remains programmed as for the dose
brewed previously;
2.
repeat these steps for the other three
buttons; any time a button has been
programmed, by pressing the button
with the spiral again, the LED of the
programmed button(s) will remain
switched off.
3.
once you have programmed the first 2
buttons of the first control panel from the
left, the dosage programs set according
to the above will be stored in the memory
and the 3rd button (the one with the
spiral) will return to its function as a
continuous brewing on/off button.
N.B.
Programs for the first group from the left
will become the default programs for the
remaining groups (unless you wish to
program these groups differently, in which
case you will need to follow steps 1 to 5
for remaining control panels). The leftmost
control panel must be programmed first;
indeed, if you are going to program this
last, all its settings will be automatically
transferred to the other groups.
It is recommended that each group be
programmed separately, from left to right.
Each button also works as a switch and,
therefore, you may stop coffee brewing
at any time, whenever you have obtained
the desired quantity, by pressing the same
button.
Fault warnings
If the wheel does not send any signals to
the electronic module for more than 3-4
seconds, the LED of the button which has
been pressed will start flashing.
This means that:
A) water is not flowing over the wheel
and therefore is not reaching the coffee
groups, which may be due to:
1.
the ground coffee being too fine, i.e.
coffee gets brewed too slowly (drop by
drop) and therefore the wheel cannot
measure the water flow within electronic
module factory-set time.
2.
insufficient water flow through the
groups (i.e. onto the coffee powder),
probably caused by a combination of one
or more of the following factors:
• partial blockage in one of the pipes;
• a malfunctioning motor pump;
• a malfunctioning solenoid valve;
• partial blockage of the diffuser screen.
B) there are calcium deposits inside water
flow counter which prevent the wheel from
turning properly.
C) the wheel itself and the sensor (top
part) of the counter may be faulty.
Coffee brewing
Take a portafilter and place some ground
coffee in the filter itself: 1 dose for the
small filter, 2 doses for the larger filter.
Press down on the ground coffee with
the supplied tamper and engage the filter
holder again into the bottom of the group,
then press one of the buttons with the
symbols for 1 or 2 cups.
You can also press the same button again
in order to terminate coffee brewing before
its programmed stop. Should you need an
unusual amount of coffee, you will be able
to use the button with the spiral symbol
and press it again once you have obtained
the desired quantity.
