that is an extremely unique dishwasher
you have there! and from 1962, my favorite year of the 60's!
i have never seen a wash system like that before, thought there was some type of mini spray on the bottom as well as that central tube but i guess not. it's just a filter in the middle of the bottom?
would love to see more pics, close-ups of that center tube and bottom filter (i'm ready for my close-up mr turquoisedude)
that motor looks just like the motor on my 2 60's model frigidaires and it is still available, at least i know where a couple are. i might know someone who has pump parts for you if interested.
all in all a beautiful peice of early 60's history! and one beautiful dishwasher! amazing we can still find these machines! and it's 47 years old and looks like new!
congrats
