I had shut down my hot tub last winter as per advice from Cathy from aqua tech now I am wanting to start up.
I had filled the tub and started the heater & circ pump at operating fine however I’m guessing it’s a temp sensor of some sort…?? because it states it is OH at 40-45 degrees then goes into watchdog. the h20 is cold … I shut off the outside breaker then try again in a few hours it starts and begins to heat then goes into watchdog within the hour…
