Hi, I have rotospa that has been giving me troubles. It would intermittently stop pumping, and a few seconds later display FLO on the panel. Unplug and plug back in resets it, and it would be good for a while. Since the pump stopped first, I suspect it might be thermal in the motor so I replaced the whole pump. Didnt fix it.
I pulled the heater assembly out to get a better look at the flow sensor, and this one has the in.flow sensor that I'm not sure how it works. There 3 wires, and it just sits on the tube, with nothing in the stream. I pulled it off, and tried pulling some o ring grease between the sensor and the tube to get a better 'coupling'. Since this it now doesnt work ar all. I'm tempted to get a new heater assembly but I'm not positive it's not the spa pack. Anyone have any experience with these?
