I have a Pentair starite max e therm pool heater. The heater turns on and then turns off then turns back on. It takes 3 hours to heat a spa to 101 and I am a new pool owner, had no clue that the heater wasn’t properly working and I am probably just wasting a lot of gas with it going on and off.
I am trying to diagnose this step by step. I already changed the HLS switch with a new one. Then I switched the values between pool and spa.. noticed the error doesn’t appear for both, only the spa. So heater works fine when it’s set for the pool. I have Jandy electric valves and not sure if that’s broken. The filter was 25 psi when valves were turned for pool and then 30 psi when valves turned for spa.
I have narrow the problem down to it being a water flow issues. The heater works fine on pool; it doesn’t turn off and no error code. The minute I switch the valves to spa then within 2 minutes the error shows.
I am skeptical that backwashing and cleaning the filter will fix this because the heater works when valves are set to the pool. My only guess is that valves could be broken.
