"And even has a spot for Jetdry."
Honestly, do people think that rinseaid once came about in the 80s?
I'm cautious about the fact that its a model from the 70s. It seems that particular GE machines from the 70s get a bad rap on this forum (You only have to look).
But, considering that, this machine MAY be one of the "Potscrubber 2" models, which ditched the wash tower for a short amount of time, and provided a 3 level wash system (at least I think so, anyway)
Since it is a portable, I can't be the plastic tub model with the upper wash arm (rats). I watched for those for a year after I saw the first built-in model, hoping GE would introduce a convertible portable model, but they did not and shortly after that, KA introduced the 18 series.
