Response to Hi, I have a 1.5hp Hayward Super II pump. In april it simply hummed but didnt rotate. I opened to see that nothing was blocked, all was free. all of a sudden it ran fine. It has run since April full time not cycling. The only time the pump stops is during cleaning, backflushing, etc. Today I turned it off for backflushing and it has the same humming as in April. Could this be a start capacitor issue? Where is that located in the pump and if yes how do I trounle shoot/replace it? Thanks
