Thanks everyone. I will network around and see if I can find someone who can come and diagnose my machine gratis or for trade to get a definitive diagnosis. (My dear partner lost his job on the same day).
I already spent $300 on it 4 years ago replacing the outer tub and drive spline (which you all so kindly helped me diagnose). Maybe I can sell it for parts or something. It also needs replacing of the tub suspension rods (have been manually adjusting the spin cycle to medium for a couple of years). It's in good condition otherwise...clean, well-taken care of. <sigh>
In the meantime, a kind friend brought me a 15 yo Sears, direct-drive, Kenmore for free! I'm grateful to be able to laundry at home again. It's amazing how things work out.
Blessings to you all. Alice
