Our service dept asked me if I had time to go out with the service rep and see if the two of us could figure out what the problem was because it was a potentially dangerous situation and it should not be possible to get a voltage reading in the hot tub's water after the GFCI trips. Scott, one of our top service reps, and I drove out to take a look at this Park Avenue spa. When we got to the home, we sure enough got a low voltage reading in the water of the Park Ave. His electrician had come out also to see if he could help and for a second the four of us, including the home owner, were scratching our heads.
