silly repairman
Thomas,
Whatever the problem may be - and the five listed above all sound well possible, that "in-duh-vi-duh-al" didn't know what he was talking about.
Parts might not be easy to get, but they are out there - especially this club is brilliant at finding things.
And that machine was built back when 39 years of service were nothing. In fact, Frigidaire did an ad not too long before that one was built in which they boasted "our test showed the first major repairs only after 40 years of service!"
Whether in water consumption, cleaning quality or reliability, this machine places very well compared to the stuff on sale today.
My advice: Keep it, don't turn it back on again just yet in case something is just loose and might end up bent beyond help, wait for some of the more experienced members here to write in. They will...
Oh, I saw two working Rollermatics and a couple of 1-18s at ARC in Fort Collins last sommer/fall. So the stuff about no parts nowhere, nohow is bullshit.
(Silly me, you may not know the names - those are machines sharing similar characteristics to yours).
