Pump Motor Shuts Off After 10 seconds

[jim1504]

I have an inground pool/spa with a 3/4 HP Pentair Whisperflow pump. The pump motor will turn on for about 10 seconds and shut off before getting a prime. After it shuts off, it will not immediately turn back on - it will turn back on after a few minutes. The impeller does spin. Anyone have any ideas? TIA

Is there a thermal/ current overload relay that is cutting the power? Could be the pump is drawing too much current and is cutting the electricity.

Is the problem sudden, or did it happen after a period of no use?

Thanks for the help. It does seem as though something is cutting the power since there is a short delay before the pump will turn back on (even manually). Never had a problem before with the pump itself. It has run everyday since the problem appeared yesterday. I double checked the electrical connections on the pump and at the switch.

FYI, the capacitor was defective. After replacing it works perfectly.

relief no doubt.
