It'd be best to return it to the factory in Millville, NJ. This time of year however, I wouldn't expect to get it back for at least a few weeks. Call (800) 352-5630, extension 236, then make arrangements with Jerry in the Repair Shop. Millville, NJ is about an hour's drive from the Delaware Memorial Bridge - total driving time from Annapolis is about 2 1/2 hours.
If the ice tray is "yucky," - I'm guessing that the epoxy lining from the mold is coming off - which will require that the mold itself, be replaced; this is best done at the factory. If the epoxy lining is coming off, it is caused by winterizing the machine with pink anti-freeze. Anti-freeze (of any kind) should never be run into the ice machine. It should only be winterized dry.
