At this point programming can be started for the four coff ee selections. When the desired quantity of coff ee is
obtained, press the selection once again and the dosing will stop. The same operation will have to be followed for
all buttons.
By carrying out this process all the groups will be programmed automatically.
The selections that are already programmed will appear with their LEDs off . When this happens it is still possible
to modify the dose in the same manner as indicated above.
If during the dose programming the LED being programmed fl ashes, this means that the fl ow meter is not sending
electrical impulses to the control unit, and they will therefore not form a part of the programming. It is recommended
that the fl ow meters be checked.
NOTE: If the machine has a display, follow the indications as they appear on the screen (see the section on display
operation).
