Been there, done that, though it has been quite a few years. I would
still be glad to fix things that way if possible.

I had exactly the same thing happen. By that I mean I had clothes
washer board/s fail after only about 5 years. I kept the bad boards but
have not yet tried to delve into exactly what is wrong with them. When
the washer needs replacing I'd love to get one with a simple
electromechanical timer. Unfortunately, I'm not sure that is possible
any more. The guy at the Fixit Shop where I usually buy my appliance
parts did not think so when I mentioned that idea the last time I was in
there. This crazy washer we have now has two motors: a pump motor which
runs at line frequency, but the main mechanism drive motor is PWM'ed at
varying frequencies up to I think a few KHz. Who needs it? Not me!
Washing clothes is not rocket science!

Yeah, us too, as far as manually cooking goes. But so much of the
control stuff is electronic I don't think it would be very easy to
circumvent. At best, it would probably look pretty bad I think. I
should probably really get serious about a whole house surge suppressor,
though I realize that still does not remove 100% of the vulnerability.
