Went out to get in the hottub last night and it wasn't so hot. Today found out that the breaker wouldn't reset. Unplugged things one at a time and found out that it seems to be the pump tripping the breaker. The pump motor shaft spins freely and I have no leaks. In fact, I changed out the wet end last week and it worked fine until today. Any thoughts on what I can do? Would the pump just start tripping the breaker all of a sudden?
