Recently I Got a master spa MS8000 I got it all wired up and proceeds to start it up after priming mode the gfci trips I went about disconnecting the heater element to test to see and it still trips so I also disconnected the ozonator and it still trips although during priming mode I am able to start the jets 2 and 3 but will trip the breaker if I try and turn on 1 or adjust the temp also as well if I unplug the ozonator or circulation pump i can turn on all three jets I checked voltage going into circuit box on spa and it is reading 242v and when I am able to run all 3 it drops to 241v if I disconnect the temp sensors it didn't trip the gfci although it didn't even go into priming mode and did flash codes for sensors and temperature. Pleeeease help I'm at a loss
