It's a Hotpoint. 

Eddie, that was the TOL JCPenney by Hotpoint that offered a Sanitize final rinse optoin, someting GE never offered.  Wish they had. 

This model does use the SAME pump and motor that even the best GE DWs of the time period used, so it does have a small disposer blade that will grind up bits of food and redistribute it through the wash chamber. These DWs can and do produce acceptably clean dishes if not overloaded with food waste, they relied on the many water changes to get rid of any food particles.

Sandy you are correct about door gasket problems of the HP line, This DW does have a porcelain tank and door and while they did not rust out in the aggressive way that the GE plastisol tub machines did they were still no stranger to some rust issues in the sump and at the lower inside edge of the door.

Reliability of this and GE DWs in general was quite good, certainly better than MT DWs and believe it or not at as good as KA DWs. That is not to say that the two later machines were not better built and had the potential to be repaired and end lasting longer, but in a good home the GE-HPs had fewer service calls in the first 10-15 years of ownership.

One thing to keep in mind was that MT did build a very reliable washing machine for a long time, best in the industry from about the early 1960s-into the early 1980s when WP passed them with the DD washer. They did this with the washer partly at the expense of great performance however. But when it came to MTs great performing DW and there good performing dryers, neither of these MT appliances ever achieved top reliability as there were several other brands in both categories that always out did them in the reliability area.
