I took my dishwasher apart. Because I had crud on my upper rack glasses. I had tried everything different detergent, rinse aid, those cleaner things. Turning up the hot water heater. Well when I got down to the grinder all sort of junk and bits of plastic were in there. So I cleaned it all out and put it back together, but I can't get the lower spray arm to screw down. Any Ideas?
Thanks for all you help and time. Cara
