Pool Heater Won't Start
Вставка

- From www.swimmingpoolsteve.com/pag... - If you have a problem with your pool heater in that it will not fire or turn on, this video will discuss the most common reasons why this happens and what you can do to resolve this problem.
Most commonly the pressure switch inside the heater (safety switch) is not able to close due to low pressure or low flow in the pool system. This could be from a variable speed pump that is running on too low of a speed setting, but most commonly this problem is from a restriction in your filter. If you have a sand filter be sure to backwash it thoroughly to resolve this flow problem. If you have a cartridge filter be sure that your cartridges are cleaned with a degreasing agent (not just rinsing them off). If these tips do not resolve your heater firing problem then consider having a heater cleaning service performed by a qualified gasfitter.

Swimming pool Steve. My Hayward pool heater wouldn't start up. Your advice on using a degreaser on our paper cartridge was the solution to our problem. You know your stuff my friend. We learned a troubleshooting tip that helped confirm that the saturated filter was the problem. Hayward advised to remove the cartridge filter then reassemble and start the pump temporarily. Upon doing so the heater started up and worked like a charm.
Thanks for posting. Your advice was a BIG help.
Dude! You just saved me an expensive service call! Backwashed. Rinsed. Heater kicked right on. Thanks!
Backwash/Rinse worked like a charm! Thanks so much for posting this Steve!!!
So happy this was able to help you out.
Backwash and rinse for 5 and 3 minutes respectively did the trick Steve...TY from Toronto, Canada!
Back flushed and rinsed the sand filter and everything works perfectly. Thank you so much!
Will try it out. Love the simplicity of this guy's explanations.
Cheers - thank you.
Great tutorial. Heater would not fire. Backwashed several times. Looked like it was clean but it was not. Saved me hundreds of dollars in repair tech fee.
Thanks! I'm a new pool owner. I try your method and it worked! Just in time for a big pool party!
That worked wonderfully back washing my sand filter my pool company was here to try to Fix it and was having trouble getting it to ignite. I went inside and googled it and this video came up. Told them about it and they tried it and it worked. Thanks 1 million
Glad this worked for you. Did the heater end up working fine for you after this point?
Thanks Steve I just wanted to share my experience with my Hayward H1000 ... I tried everything you described and you are 100% correct for normal operation when pool filters naturally get dirty and disrupt flow... however my heater wouldn’t start after turning it on in the spring after 6 months of no operation and a cold winter. What I did is I removed the lid (removing the 6 screws on top of heater) did a quick overall inspection on all connections and then realized the fan wasn’t turning but can hear the electric motor running attempting to get it going ... so I realized if the fan doesn’t start, neither will the heater - they are linked. Turns out all it needed was a little kickstart just by rotating it manually a few turns. It probably was dirty, dusty etc because of the layoff and winter. All good now.
Thank you for this information. The concept is similar to pool pumps (and any electric motor) in that sometimes you need to jog it or spin it manually. Corrosion develops on the motor internals and an electrical connection is not being made. Moving the motor position will allow a better connection and the motor starts.
thanks for your feedback. I actually did call a licensed tech. but i also told him i read about orifices and so i shut the gas off fro m the house and turned the heater off and cleaned the orifices. i did strip them and when he came he just put it back for me and voila it worked. I appreciate your feedback. thank u again.
Great tips Steve. No fluff no BS love that!!
Cheers
Thank you...thank you...thank you!!! Was going efn crazy!!! Followed your instructions and "bam", the heater turned on...saved me a alot of frustration...thanks again!!!
I like your relaxing voice and simplicity in explaining. In addition to what you said, spiders will block the gas nozzles and the best way to clean it is using tobacco pipe cleaner (bristle) . It worked for me after leaving my filter unused for 3 years for this stupid reason.
Thanks a mil for this Steve. Solved the problem in exactly 7 minutes! :-)
Glad this information helped you out. Cheers.
new heat pump not starting ... problem found, filter obstruction !! Thank you Steve!
Such a small web, such a big problem. Thanks for the info. Fixed it quick.
hey steve I did a backwash and no improvement . I have a brand new aqua comfort heat pump. It worked but lately it just sits on DEF mode then attempts to start and just fails and goes back into DEF. do i need to clean my filter really good? maybe open it up and clean all the DE and start new?
Omg thank you, you just saved us thousands of dollars.
Thank you.Very helpful info.
question, i bought a used hayward H100iD1 pool heater, the person i got it from was using it with propane, d i need a special kit to convert it to natural gas?
Thx bro now I got my pool heater working :)
I am happy this helped you
Steve I have a 5 year old Hayward H series pool heater. Been working fine. Noticed this year sometimes the Mode button was a little slow to react now this morning cannot move the heater into operational setting from standby and the display window is showing 56 ( or maybe that is "stuck button")? We had extremely violent storms last evening come through and I'm wondering if there is some condensation behind the button sensor in the control panel. Is there a way to easily pop out the panel or something I can do or perhaps should I wait to see if the sun dries it out and it fixes the problem on its own. I know the temp of my pool is not 56 so that is why I think the panel is stuck. Thanks for any help you can offer.
I cleaned the filter cartridges this morning and just like magic the heater fire up. Thanks for the information, I was going crazy because last week the heater worked and then it just stopped and there were no indicator lights to look for a possible cause. You were spot on the filter pressure rose 10 PSI in the last week and I noticed that the skimmers were not keeping up with the spring pollen. Back in business and the grandkids are frolicking in the pool again.
Very detailed and clear info. Thank you..
I am glad this info was helpful for you.
Hi, we’ve just fitted a brand new tagelus pool filter, which is glass not sand, and our dream heat pump has the error code we 03, will doing what you’ve said work for glass as well a sand?
My Hayward 350 is starting it's 3rd year. No electricity is shown on the control panel. Under the panel is a 3 amp fuse that was blown. I replaced it but still no light on panel. What are likely causes?
Dude. That's smart thinking!
I dont know if itll fix mine but it's a smart idea nonetheless
A guitar string D or G fed through the pilot tube wiggled and poked works for mine ..
Three years ago, my IF code was a stuck regulator diaphragm on the back
of the gas valve. If you DON'T know what you are doing, leave it alone
and replace the valve. If you have a clue about mechanical stuff, you
can remove the rear cover of the valve, and check for the disk sticking.
This winter it was clogged jets in the big black pipe at the bottom.
7/16 wrench to unscrew the jets, tap out the gunk, and clean the pipe if
you can. Replace the jets into the black pipe, and test. IF usually
doesn't involve the ignition. If start the heater in the dark, look for
the orange glow in the burner window, this will tell you the igniter is
likely working ok. Can also be caused by low fuel flow, or in my case an
LP tank with less than 1/8 full. Not enough pressure head in the LP
lines to get a good solid 'WOOOOF' when the gas comes on.
My Jandy LXi fires but won't stay lit, any ideas? DE filter is clean.
My pool heat pump not started, I have checked the gauge. Gauge nob in on 0 zero. What should I do to start
When I turn my heater on it trips the breaker and shuts down the pool filter. Is it possible I have a bad switch. The heater was working lat week fine.
good advice
Right on Kevin, thank you for the positive comment.
Hello Steve. Raypak/Weather King. I verified that I have adequate flow. I changed the pressure switch. Starts to run, shuts off, then fan only, gives HP code. Cycles 6 times then eventually HP6 code. I disconnected the feeder line to the pressure switch and turned the pump on. Getting good flow through the tube. Any other suggestions?
I have a sta-rite SR333na pool heater. Works perfectly with the heater covers removed but when I put them on the heater clicks off. All electrical parts have been replaced. No error lights or obstruction to blower
I have an electrical heater, I did everything you recommended, even remove the filter just to make sure there was nothing obstructed. There is water going through the heater but still “no flow error” and heater doesn’t fire up. Any other cause for this?
Thanks
That worked! Thanks buddy
Nice!
Hey Steve, I have a Hayward Propane 350k BTU heater, just installed it. The heater will fire up and then shut off, any suggestions?
Call the installers back to fix it. Most likely there is a problem with the supply line (gas) and often they are too small to supply the amount of fuel needed for these giant appliances. Especially propane which is certainly more finicky than natural gas.
I got a brand new hayward that started giving me an AO and IF code 2 months after we replaced the old one.....
someone said i have mudauber wasps nests blocking my h200 from lighting. what can i do?
Call a gas technician to come and perform a heater cleaning. It is a surprisingly good value for your money if you want your heater to last a long time.
my heater is brand new and won’t start...no power to the ignition and fan. I have an earth filter. Thanks
Hi Steve, I just gave my sand filter a good backwash and rinse...Hayward heater still not firing. I hear fan and clicking. Should I try to clean it or in past the lines were blown out with high pressure air? thanks!
I opened the panel and gas lever was OFF. Turned it on and blew out the lines with high pressure air while in there. Fired right up and running fine so far. It's amazing, but when things don't fire up or turn on it's usually no fuel or power.
Thanks!
Cheers Phil
Much appreciated advice helped me change my Jandy salt cell and high-limit switches this weekend. Saved me at least $500!
What if heater wont power on at all. What are some things I should look at when diagnosing the problem?
First thing for sure is simply to start inside at your electrical panel and make sure the breaker is on, and not tripped out, and then go to the disconnect near to the heater and verify that it is on as well. If you are an electrician or have been trained for testing electrical values safely, then you would use a multimeter to verify that the voltage is what it should be, and then follow it from the house panel to the disconnect, to the internal power connections in the heater. If the heater will not power on at all then somewhere along the way your circuit is being interrupted. Would not be crazy to find something like a rodent chewed through one of the lines at some point. If you have a pool heater in a cold climate area then it is important to actually power off the breaker over the winter. If you just turn the heater off but leave the breaker on then the internal transformer in the heater will be receiving power still and will be warm enough to attract pests.
i have I F error code and i cleaned my NEW filter only have had the pool opened for 2 1/2 weeks. filter is brand new. my heater was working like a charm for past 2 1/2 weeks and now kaput. or IF error. i turn it off wait 5 minutes gas that is , turn it back on and it goes to pool and then it flashes the temp I want then it says my pool is 79, which i had it up to 87, then it flashes then 79 the wheel inside starts going round and then the clicking noise then it sounds like for a sec it is going to start the green heat light goes on for about 5 secs then off. what do u think I should do. my heater is 2 years old.
I know exactly what you should do, and I hope very much you do it, and that is to call a licenced gas technician to come and diagnose this problem for you. Imagine standing in your backyard and turning on 10 big BBQ units all at the same time...but not lighting them. Just turning the propane gas on full on all ten units. Would that make you nervous to stand in the center of 10 BBQ units all pouring propane out? It should. Your pool heater is the same size as 10 BBQ units and you probably have your face six inches away from it as you are reading IF error codes. If your heater does not fire up properly then feel free to turn off the system for a second, and then backwash your filter really well. If the heater continues to not fire up after that then you should stop trying to diagnose the problem as there is no other testing which you can do that is safe and likely to resolve the problem. I hope this info is helpful.
I have this Hayward heater. It has been working fine this season. I had it off for a few week and went to turn it back on today. I am getting an LO code. I did backwash my DE filter 3-4 days ago, so I know it is clean. Any suggestions??? My filter PSI is like 26 running at 3000.
I ran my filter on Rinse for about 30 seconds, and then turned it back to filter. Heater went on! I don't know if that was just luck or if my water pressure sensor is on its way out. Just ordered a new one on amazon to have just in case.
nice info thx
Glad it was helpful!
What happens with the sand filter. After you've back washed, and rinsed. And the heater still doesn't fire?
I just open my pool today and the flow is going through the heater and into the pool strong, but the pool heater isn't turning on, just showing the FLO on the panel. Not sure where to go from here. Any suggestions?
I have a raypak and won't fire up the digital reader says mv output fault any suggestions
Yes, I suggest that you get a licenced gas technician to come out and troubleshoot this for you. Have you done yearly spring cleaning with a gas tech? This is a service well worth the money if you want your heater to last. Also, most pool owners have ZERO appreciation for how large (and dangerous) a pool heater is. You know how when you light a crappy BBQ up you have to use a long lighter or match and you kind of lean away as you reach over to light it as you expect the WHOOOSH when it goes? A large family BBQ might be 30,000 BTU. Your pool heater is most likely between 250,000 to 400,000 BTU. That WHOOSH from lighting a BBQ sounds a lot more like ringing in your ears and learning how to walk all over again from a pool heater. I have seen a 10 pound service door blow 100' off the front of a heater that was not firing correctly.
Swimming Pool Steve I second the spring cleaning by a certified gas technician. After 15 plus years I am really starting to see the benefits of having this service done. Prolong life of the unit and less in season down times.
A question: I have a RayPack and recently installed a Variable Pump. What is the minimum pump speed for the heater to run?
Yes
One thing not covered - the heater has a pressure sensor. My heater will not start until the pump has been running about 8 hours. After that, the heater fires right up. So run your pump for a day, then try turning on the heater.
Great info, thank you for your comment. Cheers.
i do backwash but the error if continue what to do
The next step is to contact a licensed gas technician who can troubleshoot your heater (other than perhaps making sure the pressure switch in your heater is connected as they get taken apart when winterized quite often). Even when I worked for a major manufacturer of pool equipment we were not allowed to provide troubleshooting advice for heaters to anyone without a gas license. This is for safety - gas heaters are more dangerous that people tend to realize.
Brand new pool, brand new heyward pool heather. Getting error 03 when trying to turn on.
Anyone?
My filter pressure is at 20 when in pool mode, then jumps up 10 psi when I set the suction and returns to spa, causing the heater (Hayward) to throw a LO error code. I can still use is if I open the pool return valve about 20% but I would like a fix so I'm not losing so much heat to the pool. Any suggestions?
Not a lot of instant solution so this problem, but the first thing I would try is remove a jet nozzle or two from your spa to reduce the restriction to flow. Maybe you get lucky and even one nozzle left out is enough to keep your system pressure lower.
going to do 5 minute b/wash in the morning with rinse. thx for heads up. will let u no outcome
Cheers
Wireless video.
Nope. Very useless information. Wrong
Great comment - you added so much value here. Thanks for stopping by
@@serendipitysolutions glad I could help

What is the minimum speed required for this heater to run? I have a variable pump and I am not sure about the speed needed. Thanks.
That is not a question able to be answered with the information provided. YOur plumbing system, and flow rate, will be 100% unique to your pool installation. There is no RPM that is standard to generate the required flow to close the flow switch on your heater. This is why you require a gas technician to calibrate your heater and pressure switch if needed, and they will be able to tell you, based on your specific situation, what RPM you should be running at. But even then, what if your filter gets a little dirty? Now that same RPM does not produce the flow that it did before - variable speed motor RPM and flow rate is a dynamic equation and not something you will find an easy answer for online unfortunately.
Thanks a lot for your detailed answer. Both the heater and the variable speed pump were purchased and installed by Leslie's pool. I was told that 2900 would be the minimum speed, it works. However, and now my other question: what is the sense of a variable pump if, let us say, we need the heater 24/7? The 'variable speed' doesn't make sense in my view. Thanks again.
