I'm hoping someone can point me in the right direction with an issue I have with my heater. It's approx 8 years old, H100id Hayward. I haven't had any issues until now.
When I turn thermostat on, it ignites fine....and it heats the incoming water, and there's still the same hot exhaust released. But, after approx 15 minutes, it simply stops heating, with only some cool faint air out of exhaust port. I've noticed two new "sounds" this year since opening...one, it's like a fan rattling sound. And now, there's a different pitch "whirl" sound, almost like a plane starting to take off. Not extremely loud though. Other than that, I don't notice anything else...no violent shaking like I've read some experienced.
Any ideas on where I should start? Thanks in advance!!
