4 Signs Your Pool Pump Motor Bearing Is Failing

Listen for a loud screech or grinding noise A high-pitched squeal at startup or constant metal-on-metal scraping means the bearing’s balls or rollers have worn down or lost their grease.

Watch for excessive vibration or heat If the pump shakes more than normal or the motor housing feels hot, the bearing is likely failing.

Check for tripped breakers or higher current draw A failing bearing forces the motor to work harder, which can trip breakers or burn out windings.

Don’t run the pump with a bad bearing A seized bearing can blow the pump seal or crack the diffuser. Replace the bearing or the whole motor promptly.
