Yeah, cute machine but maybe not such a good design. We have one and it will get grounds packed up in the spout. I found a solution though... Once every few pounds, or more often if the beans are oily, I take the jar off and put a handful of barley into the hopper (black plastic conical area with the burrs at the bottom). Covering it with the palm of my hand, I grind all of the grain. I readjust the grind to fine and repeat with another handful of barley. Then I brush all of the dust into the grinder. I reset the grind setting and add maybe 2 Tbsp of beans. Grinding this last bit will flush the grain residue out the spout. I replace the jar and get on with life. Maybe grinding the barely is bad for the grinder but it seems to prevent the spout from getting clogged. It used to clog up so badly that it nearly got a trip through the kitchen window. Now we can cope while we save up for a grinder with a better path for the grounds. mike
