To Bob and anyone else who might be interested in the early GE Dishwashers:
I am probably one of a very small group of us that is really interested in the engineering changes that GE made in Dishwasher technology between the 1930's and the early 1960's. This approximate 30 year window is of greatest interest to me as a collector, although I am still interested in earlier dishwashers such as Walker, and some dishwashers made after the 1960's.
I am going to include a photo and several scanned images to illustrate some of those changes. I mainly wanted to comment specifically to Bob regarding the orientation of the GE dish racks, but I will try to address other changes too.
This photo shows the racks from a 1949 GE top loading dishwasher. The center Glass Tray rests within the top rack. The top rack rests on tall wire loops in the corners of the bottom rack. This method of stacking the top rack on top of the bottom rack apparently began with the first GE dishwasher models produced around the middle 1930's. GE continued this design up to 1950. Subsequent replies to this thread will show the similarities and changes.
So because the top rack rests on top of the bottom rack, the top rack could be placed in any of four positions with the glass tray orientated: (1) front, (2) left, (3) rear, (4) right. Having observed my own GE dishwashers with Plexiglas lids in place, it is very obvious that the center glass tray area of the upper rack did not get very much water lifted up from the impeller. The sides and corners of the top rack got much more water action. So, based on loading patterns that individual GE dishwasher owners used, if the gasses were not getting properly cleaned, perhaps the top rack might be rotated to one of the other three positions until the best results were observed.
Why did very little water make it to the center glass tray in the top rack? The silverware basket sits right on top of the impeller. The amount of silverware utensils in the basket, would affect the amount of water that could get past and lifted high enough to reach all the way into an inverted glass tumbler. Around 1955, GE changed the rack configuration, redesigning the top rack eliminating the center section completely and redesigning the silverware basket plus raising it a little further above the impeller (see the forth page following this reply).
