Frigidaire Dishwasher not circulating water

Dishwasher has all the signs of being old, but I try to find out the problem.
Problem is, its all plastic parts. !
Do not do what I do....If you are not comfortable with electrical and or plumbing, please call the experts.

The older appliances were better built than the designed-to-fail absolute crap they produce now. With a new circ pump that would probably have lived another decade at least.
