To obtain the best results for each product used, we
recommend the following checks:
- The coffee pod shall be slightly compressed and moist.
- The grain size of ground coffee.
- The grammage of ground coffee.
- The dispensing temperature.
- Dose of water.

Only some machines are equipped with a cup sensor
which detects the presence of objects between the
reflector and the sensor.
To ensure correct operation, the emitter and the protecti-

Only some machines are equipped with LEDs for lighting
the dispensing unit.
By default, the LEDs switch on when the drink is being
dispensed and remain on for a few seconds after the
end of the dispensing; however, the on time or steady-on
of the LED can be programmed.

riNDiNg sEttiNg
If the grinding grade needs to be changed, adjust it using
the relevant knob on the grinder, and more precisely:
- rotate the knob anti-clockwise to obtain coarser grinding;
- rotate the knob clockwise to obtain finer grinding.
It is good practice to change the grinding grade when the
coffee grinding motor is working.
Note: after varying the grinding grade, it is necessa-
ry to carry out at least 2 selections for checking the
new ground coffee grain size:
The finer the grinding grade, the longer the dispensing
time will be and vice versa.
