Dakota Spas Skyler Balboa DAK25 CCAJ Had it working on 120, just would not heat, would keep temp with cover on. Hooked jt to 240, which guy I got it said he had 240. Hooked it up and nothing. Decided go back to 120, still nothing. I have power at circuit board. Nothing happens though, wouldn’t know it’s even plugged in. All fuses check good, power where there should be as far as I know. I’m lost and don’t know where else to look Yes in attached picture the black wire on top right relay is in wrong spot, moved it to keep pump running for time being

I have the same hot tub. I got it and had it hooked to 120, would keep hest but not warm up. Went to hook to 240 nothing. Went back to 120, still nothing. No display, relays don’t click, no pump. Have good voltage to board and everything
