and its the exact same one I grew up with! I think my parents bought it in 83, it went thru a motor and a pump but it was an awesome cleaning animal! I'd love to have the top of the line model from that time!
This series of WP DW still had a porcelain coated steel tank, they did this though about 1990. The inner door was a molded polypropylene panel which was the best way to build at the time.
I think I was just remembering the door was plastic so it may very well have been a porcelain tub. Thanks for the info combo! Someday will you post pics of the power clean you have in your kitchen?
