Lots of great content here but I cannot find any feedback on my specific problem.
I have a Hayward H250 gas heater that will not fire up. Pilot light goes on everytime. If I jump the TH terminals the unit will fire up. According to the troubleshooting flowchart, the next step is to jump the pressure switch. When I do this the pilot light goes out. re light pilot, jump PP, pilot goes back out. Unfortunately, this scenario is not covered in the work flow.
Anyone seen this?
