New Hayward H100id1 Heater Won't Stay Running.

[mtb54703]

I have newly installed new Hayward H100ID1 natural gas above ground pool heater. This heater replace one of the same model that was 5 years old - it was replaced due to a leaking/carroded heat exchanger.

The new heater will turn on the blower/fan for 10-12 seconds, then open the gas valve and starts sparking the igniter. There burners will lite within a couple seconds. 10 to 12 seconds after the gas valve open, it closes. According the manual, this is an indication that the control module did not sense a flame. The heater uses the igniter as a flame sensor.

Manual and schematics (page 3) for the heater are here:

I've received a new control module, igniter wire and ignitor from Hayward - none those

items changed the problem.

I've jumpered all switches - no effect. Water pressure is good - the heater wouldn't attempt to start if it didn't have water pressure.

I've check inlet and outlet gas pressure. Inlet is 8" WC (spec says between 3 and 10.5) and the outlet is 2" WC as it should be.

I've disassembled the entire heater and looked for blockages - none. Everything looks brand new.

Heater is properly grounded. I've even tried powering the heater from a different circuit

than the pump.

The sticker on the heater say natural - thats what I have.

I've let it cycle many many many times - it still never leaves the gas valve open for

longer than 10-12 seconds.

Any ideas?

Try a new gas valve. You tried everything else. that is my guess

I have the same heater with the exact same problem. Hayward sent a local heating repair guy over to take a look at it this morning. He spent about 3 minutes with it and said that he needs to order a "new board". No idea what board he's talking about, but he said it's a common problem with these heaters.

Now I'm concerned though because it's most likely the control module that he's ordering, and it sounds like that didn't fix your problem.

Did you have Hayward send a technician out or have you been replacing the parts yourself?

I have a feeling that the short swimming season will be over here in Vermont before I get this heater working.

Sorry for the delay in responding - have been on vacation.

I have talked with the owner of a local pool store who is Hayward local warranty and repair center. He wants $75/hr travel + mileage to come out and look at it. Hayward tells me he is under contract to service all Hayward products within and 50 mile radius parts and labor. Hayward also tells me he should have parts in stock for this heater. I mentioned this to the guy and he said he would need to re-read his contract - I bet he hasn't. I can see where he might need to cover the possibility that its not a defective with the heater and is an installation problem - then Hayward wouldn't pay him. But he never made any mention to me that was what he trying to do. I think he's just ignorant of obligation as a warranty center. Either that or he just like to double dip.

I didn't buy the heater from this guy - ordered online. I would buy locally if there wasn't such a price difference. And a warranty is a warranty so it really shouldn't make any difference on getting service under it.

The local pool guy was going to get me a new circuit board after I first talked to him, but he dragged his feet and a week later hadn't heard anything from Hayward so I called Hayward back and they sent me one directly but as I've said it didn't make any difference - the burners still won't stay lit.

I'm calling Hayward again in the morning and see what else they might suggest. If this isn't resolved by the end of next week I'm ordering an different heater and making a lot of noise to get Hayward's attention.

I had the same problem. It was the gas valve believe it or not. Also would you be interested in selling me the spare board. Mine just quit.

since igniter acts as a switch to tell gas valve there is a flame present try removing igniter and sand the two stainless prongs to remove any coating that has built up ,not detecting a flame through the coating shuts gas valve off after 10 seconds . once I cleaned prongs thouroughly gas stayed on

I have some good news for you. We to had the same problem with are Hayward H100id1 heater.

It would light and then within 10 minutes it would quit. So as you thought, we went ahead and spent

$85 on the ignitor kit. Husband put it on and "NOTHING". Just donated $85.00 to the local pool

place. He took it apart, cleaned up everything, checked for clogs in the gas line....Nothing!

A friend of ours who has his own heating and airconditioning company, we called him to pick his brain and he just started working on hayword heaters! "Imagine that"

The problem was a bad "Gas Valve"

Called the pool place to check on price and we were looking at 260 plus tax!

But wait, our friend gave us a place where to buy the Gas Valve for the Hayword Heater

called All Weather Supplies. (heating and air conditioning parts)

It's going to cost $160.00 and its easy to put on yourself.

Hope this helps somebody out there

I've check inlet and outlet gas pressure. Inlet is 8" WC (spec says between 3 and 10.5) and the outlet is 2" WC as it should be.

The 8" of inlet WC was when the heater was not firing,. Yes?

What was the inlet WC while the heater was firing?
