6.11 Programming of dispensing keys
All the dispensing keys , , , , and
are equipped with a self-learning memory.
Once they are programmed, they supply the same drink quantity
at every subsequent command.
Their programming is obtained as follows:
- machine on and ready for use;
- container positioned under the dispenser;
- press and hold down the key to be programmed (or re-pro-
grammed) until the drink reaches the desired level;
- the display will show
“PROGRAMMING”
;
N.B.: The message displaying is accompanied by the sound of
an intermittent buzzer.
- release the key to automatically set the dosage dispensed;
- a subsequent short pressing of the key (less than 1 sec.) allows
the dispensing of the programmed dose.
The programming of the keys implies at least one dispensing in-
stance for each machine key.
N.B.: The programming of key is obtained through function
“HOT WATER PROGRAMM.”
in
“ON”
mode (see “6.14
Menu-programmable functions”).
N.B.: The button can be programmed by pressing the jug
button first and then by pressing (and keeping pressed) the
button till the beverage reaches the desired level.
Important
Even if the machine is cut out, it keeps the programmed data
in memory.

6.12 Grinder adjustment
Grinding adjustment changes according to the Country in which
the machine is utilised and according to the coffee blend utilised.
It is a most important operation to obtain the correct density and
cream quantity in the drink dispensed.
The grinding has been set during the testing phase according to
standard values, but adjustment modification is possible in any
case.
- Open the front door (ref. 13, fig. 1-10), rotate the knob (ref.
18, fig. 10) anti-clockwise to obtain finer grinding (the index
moves towards a lower value), or clockwise to turn to a coars-
er solution (the index moves to a higher value).
Important
Depending on the coffee blend utilised, fine grinding (index
on low values) increases the density and creaminess of the
drink and the connected dispensing time; vice versa a coarser
grinding (index on high values) decreases density, creami-
ness and dispensing time.
Danger
Do not rotate the knob (ref. 18, fig. 10) anticlockwise to the
limit stop; this operation causes the jamming of the grinders
and the machine blockage.
Important
Should the grinders jam due to the presence of foreign bod-
ies in the bean blend, the machine locks showing message
“GRINDER ERROR” on display.
It will then be necessary to place a call with the AUTHORISED
SERVICE CENTRE (see “7.3 Jamming of the coffee grinder
unit”).
