SOURCE: I'm getting an 'SF' error message on my H series

SF is a thermistor or hear sensor error. If the heater is not reseting it self after a few minutes then you may need to replace the sensor. Yes you probally can do this. On the left side of the water header their is a small tube like thing that slides into the header. It will have two wires comeing from it and you will follow these into the heater and around to the front panel. When they get to the circut board you just un plug them and string a new one in it's place. Good luck.

SOURCE: Hayward H250K gas pool heater error code

Low Flow errors are not necessarily real. They can be caused by improper adjustment or a defect of the pressure switch. Locate the pressure switch. Verify that the "switch" makes contact. Adjust the dial, reducing the distance the switch has to travel to engage. This will effectively lower the operating pressure required to operate. Keep adjusting until the unit stays on.

AO will apply to your blower, blower tubing, or blower vacuum switch. You need to check these items.

Shows r 5 code when power is turned on. sta-rite


The R5 is a sequence code in the boot up sequence where your error is occuring. There is nothing in the users manual for these pool heaters that explains this error. Your best bet, unfortunately, is going to be to call Sta Rite. Here is their customer service number: 1-800-831-7133

I have a Laars Lite 2 400,000 btu pool heater. It


It could be that the Igniter has gone bad. Or it cold be a number of other items, like the gas valve itself. If the heater has a display panel on it, is there an error code showing? If there is, go to your Owner's Manual and find out what the code is for the heater.

If you do not have a manual, you can find one online at the following link:
