Possible Causes

Worn pump motor bearings, Debris in pump impeller, Cavitation due to low water or air lock, Misaligned pump mounting

Safety first: Turn off power before touching the pump or motor.

Check water level and air: Ensure proper water level and bleed air from the pump to rule out cavitation.
Inspect for debris: Remove the pump wet end cover and check for debris in the impeller.
Listen to motor: If the noise is a metallic grinding or high-pitched squeal, the motor bearings are likely failing.
Replace pump or motor: Replace the complete pump assembly or have the motor rebuilt by a motor shop if economical.
