Your coffee grinder has been functioning perfectly for months, grinding your beans precisely, consistently and efficiently for well-balanced coffees or espressos. All of a sudden, it has stopped dead in its tracks. We often field the call where the customer reports that their grinder's motor is running, but it’s no longer dispensing any coffee into the burr chamber. Or their coffee beans aren’t feeding down into the burrs. The likely issue is that your grinder is jammed. Not to panic - this is actually a fairly common troubleshooting issue we run into.
