I had a leak in my pool liner and one night my pool was not pulling any water and the pump got very hot. I got the leak fixed, but the pump will not pull any water. I have re-plumbed everything at the pump in case there was a leak but no luck, I then replaced the impeller and all internal seals. Still not getting prime. My question is, do I need to replace the motor? It sounds ok but I do not know what else could be the problem.
