Update on my troubleshooting, I unplugged both the ozonator and recirculating pump, which are both 120 volt, and left the heater connected and the tub ran fine. When I either plug the ozonator, or recirculating pump in, the breaker trips. I hard wired the recirculating pump back into my regular GFCI 120 volt outlet, left the ozonator unplugged and the tub has been running fine now for several hours. It doesn't seem to be heating up much at all, but I'm going to let it run overnight and check again in the AM. With this being said it seems to have something to do with the lower power connections?
Ran all night with ozonator disconnected and circulating pump plugged in on its own and no change in temperature, so I either have a combination of problems, or possibly a bad heater is causing all my problems? Is it possible that a bad heater would cause the other lower voltage components to trip the breaker?
