SOURCE: Hayward H400iDL2 pool heater burned up after only 3 seasons!

I dont know about your particular model. I do manage two Hayward 380,000 pool heaters that are natural gas fired and I have never had this problem you describe.

I also manage another dozen or so assorted other gas and propane devides. One propane device sooted so bad we had to discard it. It did this, according to the propane tech, because it couldn't breathe - there were louver type vents on the door that leads directly outside. He did, however, find a ruptured diaphram in the regulator and he replaced it. Hmmmmmm, couldn't breathe eh????

I'm not too surprised at the repair cost you cite. The exchanger is of course copper and there is the labor involved and lots of it. The age of your unit at this point is not relavent. What you do need to determine is why the unit sooted up like this. If you are gas fired, you know this is considered a clean fuel (compared to all others except electricity). What ever caused it must be repaired or you will be looking at another sooted up problem and repair ... and it will not be in three years, it could be next week.

I hope you find some value to my comments . Thanks for posting this question at FixYa.com

Positive comments welcome

SOURCE: My heater ignites and blows really hot exhaust

The water is mixed on the back side of the heater and will exit the heater at 7-11 degres hotter than it came in. This will keep people from being scalded at pool side. So what you have sounds normal.

SOURCE: What does the service symbol 1F referring to?

It means Ignition Failure. They heater went thru its startup cycle, and when the gas valve opened, the heater did not sense a flame. The whole routine begins again. After about 3 attempts at this, the heater will flash IF and then go into a lockout situation. This is a safety feature of this heater.

What is a 1F code on the hayward pool heater


The code you are referring to is actually IF, not 1F. It stands for ignition failure.
If the control exceeds the maximum number of ignition retries or recycles the heater will shut down and go into lockout. Automatic reset is 60 minutes.

H150 heater shows 1f


IF is ignition failure. Verify that you have a good Ignitor and that your gas supply is adequate to fire the unit. I rarely see the internal gas valve fail on any Hayward unit. Be careful if you have to put your hand in there. The electric circuit on the smaller heaters is not typically 24VAC, it is usually 120VAC in the U.S.

I HAVE PROBLEM WITH HEATER IS SWOING 1F IN THE SCREEN


YOur 1f code is actually a IF code which stands for "ignition failure".
This can be caused by many things, but the most likely is either the ignitor has failed, or the flame sensor has failed.

Make sure the gas manual gas valve is open. Remove from panel so that you can see the ignitor.
Turn off power, then turn back on. After 90 seconds, the ignitor should start to glow red hot. If this is not occuring, then it is likely the ignitor or ignitor wiring.

If the ignitor does glow, then the heater ignites, but still goes off showing the IF code, then it is the flame sensor.

If the ignitor glows, and the heater does not ignite, it is likely the gas valve or ignition control.

As stated above, the ignitor is most likely.

Code 1F


"IF" or" Ignition failure", simply means you heater didn't fire. Be sure your gas is on,and if on propane be sure there is at least 30% in the tank (and the valve is open).Also check whether your "Glow plug" ignitor Glows, or your spark ignitor sparks (depending on which kind you have).

1F Error Code on Hayword Heater


IF stands of igniton failure. Many things can cause this. Most notable, is a clogged or dirty burner orifice. The two middle ones are the most important. But i would clean them all out. They remove with a 5/16" wrench. Improper gas pressure could also cause this. However, you need a special tool, a manometer, to read this.

I have a h400 gas heater. keeps shutting off reading 1F code


If the heater is cycling on and off continuously the problem may be a dirty filter. Try backwashing and rinsing the filter before anything else.
