Apologize if this has been covered before. 2010 HS Vanguard. Cold and no panel lights when daughter went to use it. Found Heater/Circuit GFCI tripped. Reset breaker and spa went through power up until the point that the circ pump would normally come on. At that point, the GFCI tripped with no sign of pump activity. Disconnected common to circ pump and system cycles on without tripping but I did not wait to see if the heater tried to come on. I'm assuming it's probably the circ pump but for $180, I'd rather do a bit more troubleshooting to be sure. I could remove jumper the pump but I'd have to connect it to a GFI circuit as it may work with enough leakage to trip a GF. Any good way to conduct a power off check of the heater or is the pump likely to be the culprit?
