My hayward h400ed2 heater starts for 2-3 seconds then shuts down showing error IF. I checked the gas orifices - they all clean. Heater was working fine fo the most of the summer then started showing IF error intermittently. I replace igniter assembly as recommended by Hayward. That didn't help

Have you installed anything in your home that uses gas? Alot of times it due to low gas pressure.

When you checked the orfices did you actually remove them? or just stick a paperclip inside and clean them?

If the heater is firing ..even for 2-3 seconds the ignightor is fine. If it wasnt it wouldnt lite, period... bad call on hayward

Hayward H400 error code IF (Ignition Failure)


yes, make sure you order the correct part, youll need the model number and serial number. the ignitor has 2 wires wrapped with white fibers, usually 2 screws to remove it, and theres only one way to plug it back in. NOTE: Ignition failure does not always mean the ignitor needs replaced. make sure your ignitor doesnt turn on and glow when you start the heater. if it does, youll want to clean out the gas orifices.

(IF- Ignition Failure) It may be your flame sensor failing to recognize that the heater has fired. This will tell the gas valve to close if it does not detect a flame.

1F Error Code on Hayword Heater


IF stands of igniton failure. Many things can cause this. Most notable, is a clogged or dirty burner orifice. The two middle ones are the most important. But i would clean them all out. They remove with a 5/16" wrench. Improper gas pressure could also cause this. However, you need a special tool, a manometer, to read this.

Hayward H400 Pool heater will not stay lit


"IF" - Hayward Pool Heater Fails to Ignite: the most common reason for this problem is insufficient gas supply. The Hayward heater LED display will show a diagnostic fault code of "IF" which stands for Ignition Failure. Undetected gas pressure problems if not investigated properly may result in unnecessary replacement and servicing of your Hayward Pool Heater.

Hayward H Series 400,000 BTU Pool Heater Won't Ignite


You can not manually light it. Open the front cover look for the gas nozzles brass looking on a tube. on the right side you will see a wire going to a sensor above the next to last burner take the nozzle out for that burner. 7/16 wrench unsrcew the nozzle and see if it is clogged. use something soft to push it out. Spiders love to lay eggs in these. Spray with WD40 and reassemble should work now

Best of luck
