I recieved a free hot tub from a friend about a year ago. Just got it hooked up this weekend and the red power led is blinking. I know that the heater is bad (what my buddy said!) so i knopw I have to replace that and the thermastors, but would that have anything to do with the jet pump not working. I have great flow through the circ. pump, as i should i removed the filters to make sure it wasn't that. I have checked all the incomming power, and everything looks great, just no jet pump. the pump doesnt humm or anyhting, i checked the power at the jet pump and nothing. Help!
