The coffee is ground too finely.
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.
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).
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 the required grinding fineness by pressing directly on one of the selectable numbers in the highlighted interval.
The result in the cup will be perceived after about 5 deliveries.
