My hot tub display shows OH then 125. Not hing changes when I shut off the breaker and turn it back on. The water, the heater, everything, is room temperature. Would this not be the temperature sensor? My Google search indicated a few things other than that, like low flow or the pump isn't working. It seems to me that, in those cases, the heater would get hot, too hot, and then shut off. This error shows as soon as I turn it on. The pump doesn't go. The heater doesn't go. But it seems to me that, if the temperature sensor thinks the water is 125 deg, it won't let the heater start (and not the pump either?).
Is there some way to test the temperature sensor?
