This post was split from Hayward H250 no longer lights on first attempt Please start a new thread to post a question. Zea3
Hey. My Hayward H250 FDN, electronic ignition, gas pool heater's burner lights inconsistently and shows the error code: IF when it doesn't light. When left in automatic mode, it will eventually light. I have removed the flame sensor and cleaned a little but problem still exists. I have also checked all my grounding connections and they seem fine.
Would anyone know what my issue is?
