Could be bad or tripped high limit switch, pressure switch, thermistor, or an air lock. If it was working before you filled the tub, air lock is likely. Google how to fix a hot tub air lock for videos.

I have a 2007 Hot Spring Prodigy with temp error lights flashing. I replaced the high limit and thermistor, but no help. I jumped the built in pressure switch and everything works fine. Since the replacement heater does not have a pressure switch, is it ok to run the spa with the switch jumped? Bill
