New pool / heater (Jandy JXI400P), running on propane. Ran fine the first night. Subsequent nights it would cut out with CHECK FLOW. I backwashed and that seemed to go away. However, now the heater consistently cuts out around 82-85 degrees with a CHECK IGN STEPS error. It will run up from 65-80's with no problem then throws the error consistently at that point.
Power cycle the heater to clear the code, try it again the next day- same thing, 65 degrees to 84 totally fine then the error. Propane guy was out and confirmed correct pressure, which I think makes sense since it goes from 65 to 84 in a quick time (20-30 minutes).
Any ideas/help where to go from here? Thanks!
