Hi Chaosmaster1,
Thanks for your answer. The only error code is the flashing Flo, but I think it has always flashed this. I have water runnning through the heating tube and not air locks anywhere. Would it benefit me to install a new Temp. sensor? Also could you tell me how to test the current heating element so if bad, I can order another.
Thanks again for your help.

Flo indicates that the system thinks there's not enough water flowing to activate the heater. Have you properly adjusted the pressure switch you installed?
