I have an GE GSD500P-45AW dishwasher that stopped working in the middle
of the wash cycle. It made a loud beep (more of honk) and then stopped.
Then, a few seconds later, it sounded like it was trying to restart
itself, would turn on a half a second, honk and stop again. I turned
the knob back to the beginning of the cycle to see if that would help,
but I get the same situation - tries to start, honks and stops.

I don't know if this means I need a new motor and pump like he

but I don't know if its worth the cost of parts and installation
(dishwasher is from the 80's). No recalls on this model as far as I found.

Any ideas of what it would the problem might be and the cost to repair?
