Heatpro - Turns On And Shuts Right Off, Not Sure Why No Error Message???
We got the Hayward Heatpro for our new pool. First day we used it - it worked great!e The next day was cold and rainy and not a pool day. The day after was about 65 degrees. We tried to fire up the heater again but getting our filter going. The problem is, the Hayward heat pro kicks on, does it's job for a second and shuts itself down again. After it turns on we can feel one shot of hot water kick in and it goes right back to cold. We had our pool guy come and look at it. He checked our filter and even backwashed our pool and it's still doing the same thing. AND there is no error message. Does anyone know what this could mean?

Could be low water flow. Check the solutions for that "Possible Cause" [second column] at https://www.manualslib.com/manual/449926/Hayward-HeatproAnd-174.html?page=17.
