I have a Hot Springs spa. 2007 Sovereign model. When I refill it or if it is really cold, it pops the circuit breaker. It seems when the heater has to work a little harder it pops. When it is up to tempeture it is fine.
My local dealer said it would be $200 to come out and look at it. If the heater needed to be replaced, it would be $700. I can get a new heater for $300 and install it myself.
Is it possible there is something else wrong and not just the heater? If so how do I check it?
