This probably belongs in the BEAT A DEAD HORSE section, but I didn't find what I was looking for using the search option.
I get the dreaded FLO message on my spa (Artesian Island)
I have drained, refilled the tub. I even put the hose down the filter pipe. I've even bled the pump hoping that would work (water came out, so I figured that would have cured it).
Crazy thing is that my spa pump will work in both high and low, but the low only works if I cycle it to high speed and then back to low speed. This is a pain for me because the thermostat and heater don't kick the pump into high speed (just tries low speed, gets a FLO error and then shuts down)
Anybody got any ideas?
