Cuisinart BGB-300

I just got mine to work. It seems that so much water condensation gets into the grinder that there was rust stopping the grinder from moving. Just remove all the parts, especially the blade and basket holder assembly. Take a pair of pliers and twist the grinder stem manually to loosen the rust. Turn it a good number of times and then test it out. I didn't want to use WD-40 on something my wife uses everyday. Good luck.
