Hi all -- I have a Sta-Rite SR333NA that's giving me fits this season. I've had rodents in the unit prior to this and they've chewed at some of the cords, but from what I can tell, they haven't chewed through any. I've put electrical tape over all the chewed up areas, and that enabled me to get the unit running last season. There was additional rodent work this winter, and I taped over the new damage as well. Also potentially worth mentioning, there's normal pressure in the system (clean filters run at about 15 and I've cleaned them twice when it was up to 22-24). This is typical pressure for my pool during normal operation, so I think the heater's getting enough water flow.
I'm thinking I could do a few things from here, but wanted opinions from you! So far I've only spent $90 and done the most obvious things I could tell based on the errors, but now I feel like I'm getting to a little more guesswork. I'm very open to any suggestions, but among the options I'm considering:
Thanks much,
Tim
- E05 error/replaced SFS. When I fired it up this season (about four weeks ago), it ran well for about a day, then gave an E05 error with the SFS LED lit. I replaced the stack flue sensor a few weeks ago, and the E05 was replaced with an E01 error. ($18)
- E01 error/replaced thermistor. Initially after the SFS replacement, the system would come on, the gas would fire shortly after, then it would error out (E01) after a minute or two with the LED near the thermistor connection would light up. After doing some research here on that E01, I replaced the thermistor, but the behavior remained. ($20)
- E01 error/replaced thermal regulator. This past week I replaced the thermal regulator. Still getting the E01 error and the LED near the thermistor, but now the system doesn't fire up at all. Once I press the "Pool On" button, it goes right to E01 and the LED. ($52)

I'm very open to any suggestions, but among the options I'm considering:
- Replace the membrane/panel ($60)
- Replace the wiring harness ($150)
- Replace the control board ($240)
Thanks much,
