Replace igniter on h400

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.

Hayward H400 Pool heater will not stay lit

"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.
