It sounds like your pool heater is not firing. I would check several things: the burner might be blocked and clogged, the gas valve might need to be replaced, the direct spark module might be malfunctioning, or the combustion blower might be cleaned. One of these is probably the issue. A service man can repair all of these problems.

Hayward H100ID wont heat water

If the heater is operational, working and the top of the heater is hot, and you do hear the combustion of the gas, see flames in the burner tray area...

.... then your heater is heating the water!

If there are flames in the heater, the heater is normally doing its job. Most people are not aware of the time it takes to see a "Temperature Rise". The average temperature rise is dependent on your heater size, the ambient temperature of the time of day you would like to use your heater, the wind/breeze factor as it goes over your pool surface. Is the pool waters surface covered? etc. All of this is a factor on how quick the temperature will rise. It is possible that you will not feel warm water coming from a return fitting.

Another common mistake some pool owners make is the system is on a timer. And the desire to start the initial warming of the water starts with the flick of the heater switch and then a few hours later the pump turns off and along with it, the heater. The heater will only work, if the pump is on and circulating the water! No circulation, no heat! So if you have a timer, remove the "Off" timer pins and allow the heater to work.

Hayward Heater Problem ''AO'' error. H400IDH

Thank you for posting your question here on

It sounds as if the air activated switch the tube you mention attaches to is not working. Pull the two wires from it and connect them to simulate the switch closing. Start up the heater to see if you get ignition. If so, replace the switch.

Pool heater fires up and starts heating the water outflowing into the pool, but only stays warm for 5 minutes or less then cools and stops heating

You are tripping a temp limit switch. You either have a bad switch which you can jump the wire to confirm. This is a trouble shooting technic only. Jumping the wire permantly might cause bigger problems.

Hayward Spa Heater H100ID blower will not stay on.

I had a similar problem and it turned out to be the solder connections on the control module. The connector that is soldered to this board (comes from the gas valve) needed to be re-soldered.
