Anyone able to help me figure out where to find the heater on my spa? We have a spa that was left at our house by the previous owner and it's not heating. The manual is for models 'UHS, UHH, UHP, HU1 & PU1'. Pretty sure it's a dream maker from Googling those models.
Anyway, I've traced all wires from the control box; one goes to the lights, one to the controls panel, two to sensors, one to the motor... and that's it. I don't see any wires for the heater or anything on the circuit board marked as heater. I also traced the water lines as much as possible inside the cabinet and I don't see a heater anywhere... I'm confused...
Any help anyone can offer would be much appreciated.
