I have an Infinity Spa hot tub. Wired from the breaker panel in the house to the 50 amp spa pack then to the hot tub. After checking that the wiring was correct I turn the breakers on and it tripped immediately. I then disconnect the wiring at the hot tub and tried the breaker again and it did not trip. I then reconnected the wiring at the hot tub. With the breakers shut down I removed the straps to the heater. Turn on the breaker and the hot tub worked fine. Ordered a new heater and installed. Turned on the breaker and it tripped immediately. Any ideas of water might be wrong. I did notice when it worked without the heater that the hot tub would not shut down and there was no light on for the temperature.
Thanks for your time
