Possible Causes

Seized pump bearings, Failed start capacitor, Debris jammed in impeller, Low supply voltage

How to Fix / Troubleshooting

Safety: Turn off power at the GFCI breaker before touching the pump or wiring.

  • Listen for sounds: When briefly powered, a humming sound without rotation suggests a seized motor or bad capacitor.
  • Check for obstructions: With power OFF, remove pump unions and inspect for stones or debris lodged at the impeller inlet.
  • Try to spin shaft: Access the rear of the motor and attempt to rotate the shaft with a screwdriver. If it is stiff or frozen, the pump likely needs replacement.
  • Capacitor replacement (advanced): A technician can test and replace the start/run capacitor if the motor is free but will not start.

Do not continue to power a humming pump; it can overheat and trip the breaker.
