I scooped out a lot of material from the Upper Chamber/Shredder Ring. I think someone put some eggshells in a few days before the problem started. I have tried the Allen wrench and I can't get the flywheel to budge. I feel like I'm going to break the housing or something. I also tried the end of long wooden spoon and no joy. Wrench or spoon has worked in the past. Suggestions?
