1998 Sundance Rio, moved spa to new location, new wires, new breaker, new GFI, all done by electrician. Tried to turn on and kept tripping GFI. Electrician said he could get to run if he disconnected neautral. Replaced Ozone, heater, blower, recirculation pump, and still keep tripping GFI as soon as i flip it. Tried to disonnect evrything, and still trips. Any suggestion would be helpful. At my wits end and have spend over $1000 already. Even had local spa dealer come out, and he looked through it and said the recirculation pump was bad, so i replaced it, and still tripping immediately!
Thnaks for you help.

Are you sure all your wires are connected in the proper order inside your spa control box? ill attach the manual to your spa below.

Could you take a photo of the inside of your spa control box for me?

take a look at the wiring diagram section of the manual and check your connections in yuor spa control box.
