to start with the basics, make sure there is enough water flowing through the system to activate the heater. you can put sand filter in whirlpool or bypass mode. if there is enough flow through the system, make sure the heater isnt on bypass. make sure that the gas supply is turned on at the heater AND at the meter. if your heater has a pilot light, make sure it is lit.
if you still have issues, you will have to get a service company in

"IF" - Hayward Pool Heater Fails to Ignite: the most common reason for this problem is insufficient gas supply. The Hayward heater LED display will show a diagnostic fault code of "IF" which stands for Ignition Failure. Undetected gas pressure problems if not investigated properly may result in unnecessary replacement and servicing of your Hayward Pool Heater.

Open the main door, locate the 2 white fabric coated wires, they go down towards the base of the heater. This is your igniter, usually a 5/16 nut driver will be the tool you need to remove it.

pull off the side panel, the thermistor is located in the header and can be removed by backing out the nut, and then pulling the sensor straight out.
