Rivelia: I see coffee beans left in the area below the hopper.

Whenever you insert a bean hopper on your Rivelia and turn it to working position (with the LOCKED icon in front of the machine), beans drop in the grinding area. Whenever you remove the bean hopper, some beans remain in the area - you can either prepare a drink using all of them thus clearing the area or you can grind them away.
