Why Is My Pool Pump Making Noise?

Quick answer: Grinding or screeching usually means failing bearings, humming without spinning points to a stuck impeller or bad capacitor, and rattling or gurgling points to low water or blocked suction. Turn the pump off if it grinds.

What each sound can mean

• Grinding or screeching: worn bearings
• Humming with no spin: stuck impeller or failed capacitor
• Gurgling or rattling: low water, clogged suction, or air

What to do

• Turn the pump off at the breaker if it grinds or hums without spinning
• Check the water level, baskets, and that suction valves are open
• Never run the pump dry

When to call a pro

Bearing, seal, motor, and capacitor repairs should be done by a pool professional.
