Try this solution

Adjust the coffee mill

Possible cause:
The grinding is too fine and the coffee is delivered too slowly or not at all.

Follow the step-by-step guide:



It is suggested that you access Bean Adapt Technology in the Coffee Link App to adjust this parameter to an appropriate setting for the coffee beans used. If, on the other hand, you want to adjust the parameter from the settings menu, proceed with this guide.


Please note:

  • After carrying out the following procedure, it is recommended to deliver at least 5 coffees before adjusting again. If coffee delivery is still not correct, repeat the procedure.

  • You cannot adjust more than one grinding level at a time unless at least two coffee-based beverages have been made.

  • Press "Default" to reset the default values of the coffee mill (indicated by a star).


Press the settings menu


Select "Adjust mill"

A tutorial appears on the display with suggestions on the grinding level; if you want to skip this presentation, press "Skip". Press "Next" to continue with the tutorial.


Select grinding fineness

Select the required grinding fineness by pressing directly on one of the selectable numbers in the highlighted interval.


Press "OK" to confirm the selection

The result in the cup will be perceived after about 5 deliveries.
