Why does my Pentair pool heater say E05?
Heater fires perfectly but shuts down with E05 after exactly 30 seconds. Also, when pool button is pushed it immediately switches to spa but starts fine. My heater is a little over 1 year old. Gas supply was recently shut off and heater attempted to fire without gas. Not sure if it is related.
Why does my Pentair pool not show the exhaust temp?
“If you hold down pool on button it displays the exhaust temp. – mine was showing 80 and then flashing 40. Obviously something wrong. There is a sensor on the exhaust that looks like a bolt with 2 wires coming out of it – it’s the stack flue sensor. I took it off, cleaned the terminals, screwed the sensor back in and reattached the wire terminals.

What causes a Pentair mastertemp 400 error code E05?
I see more E05 errors that are due to things like a sooted exchanger (fuel delivery, venting), scaled up exchanger (water side), or a low water flow. I see those problems a lot more than a sensor that has gone bad. I could even buy that continued high temps could eventually cause a SFS to fail.
