Cool dishwasher. These are good performers, but serious water hogs and they do have their quirks in the early production models. They are unique. They were the first machines with GE's Permatuf tub. They were also the first models by GE to offer a full size wash arm under the top rack and forced air drying. The adjustable top rack is easy to operate. If you keep it there is a special service manual specifically devoted to this model series in the Ephemera library. It is highly informative providing a full history of the design and service pointers for specific issues. I highly recommend purchasing it. Enjoy and keep us posted.
