if code

Hey everyone!!!...I have a Hayward H200 pool heater. This year I went to turn on and everything lights up and starts but it doesn't ignite and shuts down with "IF" code. Here's what I've done.... 1. Removed igniter and tested. It glowed red hot. 2. Open gas line and clear air and dump trap, all...

I have a 4 year old H300FDP and recently ran into a SF error. I replaced the "Hayward FDXLTER1930 FD Thermistor" which cleared the SF code. When I turned the unit back on the symptoms are: Starts and fires for approx 3 seconds, then shuts off. It cycles through and does this 2 more times...
