Heater Problem

Postby captainron19 » Mon 25 May, 2009 20:58

OK I have had nothing but problems ever since I first got my Hayward H Series Gas Heater. Last year was the first full year to have the heater and it would not turn on at all. The service rep for Hayward looked at it and trouble shot and had to order a part that of course was on back order. After it was all said and done the heater needed a new control panel board and it did not get back up and running until August (end) so we barely used the heater.

Now I opened my pool this weekend and the heater will not fire. It starts to run, the heater light comes on for a second and then it shuts down. After a repeated attempt automatically the same happens and then it shows a IF error (Ignition failure)

I checked and have a gas flow, I have adequate pressure coming from the pool pump, and the burners all look pretty clear as far as I could see and I even got me shop vac and made sure there were no spider webs in place.

A friend of mine is an electrician and he came over to look and hooked the electrical connections up to his meter and he said there is 240V of electricity going to the transformer but the wire going from the transformer to the electric pilot is barely 1 Volt of electricity. I am not sure how much should be going to the pilot

I would appreciate any feedback on what I can try next. I emailed Hayward and told them of my displeasure of nothing but problems with this heater and that I think it should be replaced by them (I wont hold my breath)

most of the gas stuff requires 24V, and the valve is commondly earthed to the chassis
ignition and signal to the valve is sent via the elctronic assembly, not the transformer
best get a gas fitter or authorised service agent to look at it

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 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

JNick, Thanks
Just like to say the trick to cover half the intake area worked for the "IF" error code failed to start on my heater as well.

I'm having the same problem, heater won't ignite. I unscrewed and opened the small access panel for the igniter and then it lights up no problem. If I screw the panel back on, won't ignite again. I don't really understand this behavior...

thats the factory defect, i just instaled the tape fix., covered four rows from the bottom and works like a charm. i used aluminum tape just to be safe. taking the panel to the igniter reduces the pressure is why it works like that. Replace the cover and apply the tape in the manner explained and you will fire right up. hope this helps, i got the answer on here, just re-inforcing the fix is dead on. No codes now. im gonna contact hayward and hopefully they will honer their warranty and send the proper part out before 2011. ill hold my breath, Under 90deg water lol. hope this helps

I had the same problem with my 5 year old H250. I installed a new flame sensor and the heater fired right up.

Hi, I had the exact same problem, I added the tape and it works. Here is the problem. I have the new blower. Installed in 2011, so now I am thinking the blower sensor may be too sensitive or the tube the connects to the sensor my have an issue.

I am using the tape method now, but thinking there may be a real issue any ideas.

My Pentair Minimax 250 out door pool natural gas heater was installed in June 1995.
It has been serviced each spring by the technician who installed it.
We have had repeated starting problems when it is damp or wet outside.
It will only ignite late morning after it seems to dry. Steam will rise from the top at first for a minute or two.
This summer we called technician to service the heater because it wouldn't stay lit. Kept turning off and then
on again. Tech said it was water pressure problem...just backwash it. I said, we backwash all the time. The pressure is fine. I called again, the tech came when we weren't home and left a hefty bill. The problem seemed to go away but then started again and EXPLODED when I turned it on!! Hairs on my arm were singed
and the gas company was here in 3 minutes.
Technician came and admitted when he serviced it, he didn't take the burners apart to check for spider webs because it lit fine for him. Now...There were spider webs in 3 of the 5 burner valves.
TECHNICIAN SAID THE SPIDER BUILT THE 3 WEBS IN THE 10 DAYS SINCE HE SERVICED IT.
OMG does he think I am stupid??
I do not want to use this heater and DON'T WANT TO PAY THE HEFTY BILL from the first service.
Do spiders build webs that fast?? Can they cause an EXPLOSION??
Some one tell me I'm not a stupid consumer/customer.
