Good day all, hoping someone can give me some help. I have a hayward h250 pool heater with mini volt, the pilot light stays lit, there is lots of water pressure, and I have checked my water conectons, and they are fine. The heater will not ignite when the knob is turned on. I did some reading and saw that I could bypass or jump the wires to make the heater ignite, so I tried this using the black and white wires. As soon as I did this the heater ignited and there was warm water going into the pool, well that is great and all, but what does this tell me about what might be causing it not to ignite on its own,,,,,, Thanks for any info
