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

Hayward Pool Heater won't light?
Clean the gas jets of white spider guck! After shutting the gas off, loosen the two front cover screws and remove it, use a 7/16 wrench to unscrew each jet (8 on mine), clean it out with a pipe cleaner something similar, WD40 it, and reinstall.

Also you need to inspect the igniter.

It could be that the Igniter has gone bad. Or it cold be a number of other items, like the gas valve itself. If the heater has a display panel on it, is there an error code showing? If there is, go to your Owner's Manual and find out what the code is for the heater.

If you do not have a manual, you can find one online at the following link:

SOURCE: Pool Heater with communication (CE) Error

Code "CE" stands for communication error and describes a fault between the mother board and the display. I doubt it's the relay causing it though...

AO will apply to your blower, blower tubing, or blower vacuum switch. You need to check these items.

(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.

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...


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 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.
