Hayward H100ID1 Won’t Ignite

Hello,

I have a Hayward H100ID1 that doesn’t ignite. The blower runs, igniter clicks but no flame. I tried opening the gas valve and made sure all the pieces inside were functioning and not getting stuck in a closed position and reinstalled. Still no dice. Trying to avoid purchasing a new valve as I fear that there could be no other issue since the igniter is trying to light, that should mean all circuits and safety circuits are being closed, right?

Welcome to the forums.

I don't recommend opening a gas valve.

There should be two wires on the gas valve. White is neutral and violet is switched 120vAC.
Connect your meter there to see if you're getting the AC voltage during the sparking.

If you are getting the 120v then check the orifices in the gas burner.
They are tiny holes and are easily plugged with spiders nests.

Thanks for the reply, Pjmax. I’m reading a voltage of about 117 through the two connectors while the system is trying to ignite. Otherwise, negligible voltage. The orifices of the gas nozzles appear free and clear. Any other ideas?

Do you have an ohmmeter ? Check for continuity on the gas valve with wire disconnected.
It it doesn't show any continuity.... it's open and defective. A rare problem.

Thanks again, Pj. I’m not reading any continuity between the two connections, I tried with the switch on and again with it off. Thank you again for your help, you're awesome.

I narrowed it down to the solenoid coil. Where could I find a new one of these? There’s no part number labeled on it. There is one for the entire solenoid/valve but not the coil itself.

Yes.... that's the part that goes bad. The same part that every other Hayward owner is looking for. What make that valve rare is that the coil is 120v as opposed to 24v in most of the other valves.
