I just hooked up my heater and have an IF error code.
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.
There are a few reasons that this might be happening. They range from air in the gas line to inadequate gas flow. Start by checking the installation
SOURCE: I just installed a new Hayward H400FDN and it will not stay lit.
I had the same issue...you don't have enough gas pressure.
SOURCE: Error code LO
Is the heater installed indoors?? if so you'll need a vent pressure orifice kit.
if not check your water press. (below 18 PSI on filter) Place filter on "recir" if it fires and stays on . it's the pressure.
check to see if all connections a set tight hi-ltd switch wire harness etc.
SOURCE: hayward pool heater c4205 has error message of LO
lo usually indicates insufficient water flow and/or pressure switch malfunction.make sure filter is clean and pressure is in normal range

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.
