Well
I agree $50 is wiser than 100. Get more pics, even if you're only offering $50.
GE had lots of differences in the racking systems, from "remove the top one to load the bottom"(cheap) to self-rising ones, fold-away, etc.
The script beneath the dial should say POWER SHOWER, which is a desirable option. This also means it's a spray arm and center tube model, damn fine washing.
My PlastiSol interior had rust holes through it, mine were easily repaired and not a leak since. But the reputation ain't great. The motor's were prone to fail, and parts are very NLA. If racks are bad, you're out of luck it seems.
But my $20 dishwahser, with much work and repairs, around $80, washes wonderfully. AND IT IS FUN
