Older hot tub will not fire up - Baja Casita


Aug 11, 2015
We have been using this older (early 90s) Baja Casita 4 person hot tub 2-3 times per week but now nothing is working, GFCI good and both sets of breakers are good. I am getting full power into the box. My question is where to start, I am decent with wiring but not sure if I start with circuit board or relays or what?

The pump and controls have a premier pump and pool product sticker I can get model #s if needed, but cannot seem to find a schematic

When the hot tub was working the pump would always circulate water and heater just kick on when needed - not sure if that helps or not.

I welcome any advice on this issue.
