Nope Mike, this machine had to be loaded pretty much with how the spray needles were sent out from the center tube. So, I didn't get too creative with loading. And no, just the center tube. Robert will verify or tell the right number, but this tube spun at 600 rpms and had needle sprays going every where out from that center. Even in 1963 or so, I was dreaming up an enhancement to this design, put a spray arm in the bottom. (and a few others here have stated the same thing) The tube in the middle. Some, I think 1963, had a "constant rinse" type of mini spray arm twirling from the top of the tub. The pump did send a huge amount of water quite fast through the system. I've never before or since seen such a brute force of water draining form a dishwasher. I believe the 1964 or 1965 model year was the last year of this design. The following year Frigidaire came out with an actual spray arm type of dishwasher. And talk about cavernous capacity, if ya knew just how to load it. A friend of our family was a VP for GM's dealer service and he got such a kick out of my love and fascination for Frigidaire appliances. But he did admit to me that Friigiaire's dishwashers were the weak link in the family of products. I know that everyone I knew in our subdivision who had these dishwashers gleefully kicked them to the curb when the interior porcelain started rusting/leaking. Everyone was replaced by either a Maytag TOL or KA superba. And evgery housewife literally said, now I can put glasses in both racks if I want.
