Heater Problem

[PiPPi]

Thanks for the help I did find the problem. I removed the small copper jet tubes from the gas pipe and 3 of the 5 were completely blocked by spider webs. Actually they were little cocoons with dried up bugs in em. At first when looking at them they were so dense that they looked like someone shot white caulk into the holes.

once I cleaned em out the heater fired up just fine

Yep, that's the ticket!

I have a Hayward H250 that's about 7 years old. Having the same issue as described here where the blower turns on/off every 30 seconds to a minute. There is heat coming out the exhaust on top, but the blower keeps turning on/off. For the people who posted about covering holes with tape, what exact holes are you referring to? Do you mean the vent holes? And if so which ones? The ones on the opposite side of the water inlet/outlet & how many? Can we post pictures or videos here?

Yes spiders can build web's that fast. Haven't you ever seen a spider build a web 100 times bigger and within a day?

I have the same problem. If code I covered it half with tape and still does not work. I have only 13 hours on this unit. It did the same thing when I first put it in. I payed a pool man to come and fix it and he charged me 75 dollar for this great fix. It still does not work. I email Hayward one week ago still no reply. That Hayward for you, take your money and run. This should have been a recall , we do live in the computer age. They know who buys there produces.

Yes they can build them that fast in fact they could have done it in 5 hours . It makes a great warm home for them

Same problem with H250 purchased last year.
I think you have the same problem. Try this (Hayward temp fix). The blower cover on the right side of the blower has holes in it. Cover up half the holes with tape and see if the heater lights and stays lit. If it does you have to replace the flame sensor with the new type. According to Hayward you can operate the heater with the tape in place with no damage. This is a manufacturers defect. My new flame sensor and installation will be free of charge.

Thanks, tried everything removed gas valve checked voltages checked for blockages all good brand new heater. Taped half the blower holes and fired right up.

I have a new 250 btu Natural Gas Hayward heater and it was working good until yesterday and all of sudden it keeps blowing outlet breaker. I have the pump and heater plugged into the same outlet. I unplugged the heater and the pool pump works. I unplugged the pump and plugged in the heater and the breaker pops. So it has to be the heater. Any suggestions would be appreciated.

Bill,

It could be any number of things that would cause this. Does the heater power up at all, or does it pop the breaker as soon as you turn it on? Could be as simple as a bad wire or switch. If this is a brand new heater, don't try to mess with it yourself as you could void the warranty. Call Hayward and arrange for a warranty service.

I just installed a brand new Hayward H400FD ASME and had the same problem as the original poster (and many others here). The tape trick worked. This thread is about 5 years old and Hayward has not fixed this issue?? My heater came with two plates, one with fewer holes and one with more. The one with fewer was already pre-installed. Obviously still too many holes.
Thanks for the tip.

I have 2- H150fd/n. They both were manufactured in 2014. I bought one on Ebay. It was new ...never installed from a person that bought a "Going out of Bussiness" deal from a pool store. I drove 2.5 hrs there and 2.5 hrs back to pickup the first one. Installed it and couldn't get it to fire up. I took it back and it was replaced with another H150fd/n. For my troubles the seller gave me the first one I returned to use as parts...or fix it. I installed the second one mid-season in 2015. It worked great. Fast forward to the end-season 2016. Heater worked fine all summer until Sept...when we really need it. It would cycle through 4-5 times and then the code IF. I messed with it exchanging every part from heater #2 that I could think of using the trouble shooting guide from Hayward. No luck. I then read this forum and used tape to cover 1/2 of the blower holes as described. Fired right up and runs fine. I'm hoping that the heater #2 has the same problem and can be used by someone. Not sure if this is a long term fix but it works!! Thanks for posting!!!

Could someone post a picture of the holes they covered, please?

[Seanboy]

I ask because I have an h400idl2 and I don't see these holes.

[DavidPoolBoy]

Hello, Thanks for the tip. I installed a new H400FD today and the install went well but as noted here The flame kept going out. I used your tip and covered 50% of the holes and the flame stayed on and all is well. Thanks

OMG. Was so frustrated til I read this post. Had a probcome out. Had a new meter put on my house. Was about to dig up the gas line! I knew it was all BS! A 6" piece of duct tape fixed it. I'm not very handy but can find the blower and blower plate in the manual. Took my cover off. There it is. A bunch of square holes to let air into the blower motor. IMPORTANT. I FIRST COVERED THE LEFT HALF VERTICALLY AND THE PROBLEM PERSISTED. ONE GUY SAID HE COVERED THE BOTTOM FOUR ROWS... SO I COVERES THE BOTTOM FOUR ROWS WITH THE SAME PIECE OF TAPE... BAM! FIRED UP FIRST TIME AND HASNT SHUT OFF FOR 10 minutes!
Thank you thank you thank you. Please read if you are having Hayward pool heater IF error code problems with the heater staying on.
