We have had this grill for almost 2 years but only use it in the winter to grill burgers, so it really hasn't had a lot of use. We love the way it makes juicy burgers, quickly. Clean up by hand washing was always easy. However, the last 3 times we used it the meat stuck to the ceramic plates. Last night it stuck so badly that it took 2 of us to pry the grill open and it ripped the burgers in half with the top part of the burger stuck to the top ceramic plate and the bottom half of the burger stuck to the bottom ceramic plate!!! Then I couldn't get the ceramic plates completely clean. There is now a brown residue from the meat that I can't get off the ceramic plates. (Please see photo) I even tried washing them in the dishwasher and that didn't remove the brown meat residue either.  Feeling really frustrated and grossed out because I can't get the plates completely clean.  I noticed the same complaint from others listed here now.
