Barista T aborts brewing process

Hi all,

my Barista T interrupts the brewing process again and again. Shortly before the water pump starts the message comes aborted. The water pump still starts, the ground coffee is soaked few drops of coffee come out then the ground coffee is ejected. The message "no coffee beans in the container" is displayed and must be deleted with OK, then the brewing process starts automatically.

There are enough coffee beans in it, they are not too greasy, the beans also slip through, enough ground coffee is ejected, the brewing group is clean.

Is there anything else I can check?
Where can the error lie

Hi all,

I emptied the bean hopper and noticed that fragments of coffee beans fell through a slot at the transition between the bean hopper and the grinder. I chopped them up and sucked them out. The connection is not really clear to me, anyway, it runs again
