I tested the voltage and I'm getting 120 from each wire so that was good. I ended up just buying all new guts instead of throwing parts at it and it fixed the problem, Thanks!

Thanks for the response. Here are pics of the board and diagram. I tested the sensors in 80degree water and the only reading I could get was with my ohmeter set at 200k each sensor was reading about 22.7. What voltage are you saying to test? The incoming 240V to the board? I'm pretty sure that's good because I have power to the jets and heater just fine.

Hi all, I have a 2005 Great Lakes Forte hot tub witha Balboa GVS500. When I turn my spa on, the only message I can receive on the display is six -'s. Here's a pic: https://imgur.com/a/vApj8Vl There's no information about this error code in the manual and I can't find anything online. Everything else seems to work though. The jets and heater work. When I turn it on, it gets to temp. I'm guessing it's just running in some default mode. I've tried unplugging the top control and turning it back on. When I do that, nothing runs. I've also tried resetting the temp sensors by unplugging them and turning the tub on. I can't get this error code to go away and just get it to display the temp. I'd like to do something besides just throwing parts at it, although if I can't figure it out I'll suppose I'll just start with replacing the topside display and the sensors if there's no better way to go about it.
