Depending on the age of the pump, it's possible for the windings in the motor to have developed a direct short. This can be gradual, may or may not cause the capacitor to fail, or it can happen abruptly. If the wiring is tight and not shorted out, most likely the motor windings are bad. (this is assuming the supply power is sufficient and has worked fine in the past.)

It is probably only getting 115V from your circuit which will cause it to overheat and trip the overload yet it will not draw high current which would trip the breaker. Can you confirm your line voltage with a meter? If it is suppoed to be a 230V line then look for a bad leg of power, again, checking each leg to ground using a meter.

Pump switching off for about 10 -20 seconds, then back on. Hapens about every hour


the little house on top of the motor has a capacitor in it 90% of the time thats whats wrong with this motor it's eather a 30 or a 35 mf .
pull this off the motor and search your area for pool pump motor repair, free testing ,use your zip code in the search, ask if they can test a capasitor for you.. wait to take capacitor off till the motor cools off
about a $20.00 fix

1 1/2 HP Pentair Pinnacle Pump keeps tripping the breaker. What would the problem be and how can I fix it?


The motor and/or electrical system is damaged and need to be repaired. With the breaker off, disconnect the motor and insulate the wire ends. Turn the breaker back on and it should remain closed without tripping. If so, it is ok and you can turn it off and leave it so until the motor is fixed or replaced.

Find a local electric motor repair shop and have them inspect the motor. It will likely have to be replaced but taking it to them insures it is not repairable and also makes sure the new one will fit correctly. A new motor and seal would likely run ~$150 or so.

Dynamo pump is locked--just hums


Try turning the motor from the back. Remove the end cover and turn the shaft. If it still hums the motor will need to be replaced.
