I have a Hayward H100IH pool heater. With the pool filter on the heater starts to heat up when I turn up the thermostat, but the heat turns off after a few seconds.


That doesn't sound fun. You could call the Hayward technical support number at 908-355-7995 and they might be able to figure this out. I hope this helps.

Please vote for this answer. Thank you.

Turned the heater unit on, the burner lit and after a few seconds, it shook violently for 30 sec, then there was a bang, the furnace went silent, the flame went out breifly but then it lit again. Is...


Sounds like you had insufficient water flow through the heater causing the water to boil inside the heat ex-changer. The Hi-Limits should have turned it off almost instantly. There is an internal by-pass, almost like a thermostat in a car radiator that could have been stuck. I would need to know if this was a one time thing or it happens everytime you fire the heater.

The fan will continue to run for a few minutes after the pump turns off to purge exhaust gasses.If it was still heating you have a problem. To reset the heater,turn off the pump breaker for 30 seconds. After that you need a repairman.

Pool heater comes on for about 15 seconds and then kicks off. A minute later it will do the same thing. Already replace hot surface ignitor probably because of over use. What ca the problem be?


I run into similar problem. Generally means filter is dirty. Run filter on RINSE or BACKWASH for a few seconds then try again. I am sure this is the cause.

How do you start the heater for the first time in the spring?I don't know where to begin. The pool pump is on and working.


Make sure all gas is on to the heater and the gas valve inside the heater. Be sure all winterize plugs are in place and tight then make sure all valves are letting flow to the heater. If the heater won't start at this point be sure you have enough gas if it is LP. You need at least 30% in the tanks to get the heater to fire. Then you will have a shut off valve just outside the heater. Shut this off and you will fine a union near this, crack the union open and turn the gas back on for a few seconds till you smell gas then shut off and tighten the union back up. let it sit for 15 or 20 min. to let the gas clear then try again. If it still won't start it may be time for a repairman. I hope this helps, good luck.

Pool heater wont start but when i turn off the pump and start back again the pool heater comes on for 2 seconds and shuts off AGAIN


Heater must have water before it will fire up. There is a delay relay that may be dozing off. Not a bad thing but should be chk'd by a pool sevice.

Service light on


I just had the same problem resolved, my mastertemp 400 would run up the temp to 82F and then cutoff, the service light flashes and then 50 seconds later the heater would restart and run for 2 minnutesbefore shutting down again and relighting in 50 seconds. Repeating until the temp setting is reached.

I had the pool guy out 3 times until he found a bad thermal regulator valve (kit #77707-0010). Once replaced the heater runs great.

He told me that it's my pool chemestry that is to blame, I had it checked (like I do weekely by me and monthly by the pool supply store) and it perfect??? I'm now questioning what caused the corroson and stop it from coming back?

I hope tis helps.
