Pool heater Hayward H series won't fire up

When I turn the heater on, it comes up with a code F1 and shuts down. I have the gas on and cleaned out all the burners. Wondering if it's the igniter?

I've had problems every year at start up with this heater.

SOURCE: hayward pool heater h series

the issue is a broken baffle in the system. there is a baffel that directs water into the heat exchanger and back out into the system. The welds that hold the baffel in place have broken off. It can be repaired if you take the unit to someone with a mig welder and have them re-weld it (muffler shop, mechanic?). there needs to be a weld on both sides. You can see the baffel if you remove the unit and look down the inlet and outlet tubes.

SOURCE: 1 year old hayward h1001d pool heater clicking

Actually, the clicking is likely causing the shaking. Inside the manifold of a H100 is a stainless steel diverter plate that send some of the passing water into the heat exchanger and lets the rest past and back to the pool. When it breaks, you will hear a 'clicking' noise at it rattles in the water path. When it breaks, the flow to the heat exchanger is intermittent and you will begin to boil the water, causing the shaking. This situation is dangerous, especially without a pressure relief in the heater or pipe. As long as your water chemistry is sound, Hayward will usually cover this under warranty even if the unit is over a year old.

SOURCE: HAYWARD POOL HEATER FIRES FOR 5 MIN. THEN GOES OUT

Sounds like it is cycling on high limit; causes are related to water flow through the heat exchanger or a faulty high limit(doubtful given the heater cycles back on). Check the internal bypass for obstructions; has anyone worked on it recently? There are usually two high limit switches with different trip temperatures; installing the wrong one could also be the culprit. Does the heater "bang" before it goes off (a sign that the water is boiling inside the tube bundle)?

SOURCE: 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.

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

The heater fires up for about two seconds then turns off. The filter is clean!


most likely your flame sensor needs to be cleaned with fine emory cloth.sensors sometime become oxidized or corroded. once burner ignites,if flame is not sensed signal is sent to shut down valve as a safety precaution

My heater starts and then after about 3 seconds shuts off


Either , you really don't have good pressure (below 18 PSI on filter) or your water pressure swith is defect.
Try placing your filter on "recir" and fire the heater , if it fires and stays on .....it's definitely your pressure -back wash.
hope it helps

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
