well I just inherited a proform magna spa. It was working fine before I took it over. I got it hooked up and it was running for about 10minutes. Then is shut tripped the GFI and now it trips the GFI immediately. I have been researching and one question I have is why does the GFI box need to be at least five feet from the tub? I have mine about three feet away mounted on a 4X6 post on my deck about waist level? Could this be the reason for the GFI to trip? Any help would be appreciated.

I'd definitely check your heater for a ground fault... heater failure can occur during start up. YOu'll need to check with your meter set to the most sensiitve ohm setting...POWER OFF>>>from either heater lead to ground... any reading indicates its bad.

I will check that. I should also comment that this spa is just a year old. It has me boggled as it was running fine for the first ten minutes.

well thank you for the tip. That seems to take care or the problem.

We have heater elements! AND I wanted to address your question about the 5 foot rule... the Gfci box is supposed be OUT of a 5 foot reach path from the spa.. in otherwords you should not be able to touch it from the spa itself.
