Difficulty: Moderately Easy
Step1
Check to see if your pump's power source is working properly. Make sure your breaker and any switches are turned on. Then, check the wiring for any areas of corrosion.
Step2
Turn the pump off and check the impeller for debris if the motor hums but then stops. If the pump is clean, check the wiring to make sure everything is as it should be. If so, you might need to repair your capacitor, or you might need to replace it outright.
Step3
Clean your filter, or replace it, if your pump seems to be working less efficiently than before. Check your pool skimmer basket for large collections of debris that might be clogging the system.
Step4
Raise the water level in the pool if your pump is taking in air. Check to make sure your skimmer weir is working correctly, as a damaged door that allows air into the system might need to be adjusted or replaced. If there is a lot of air in your pump, look for the O-ring on your pump's lid and make sure it is lubricated and free of cracks.
Step5
Remove the motor from the pump if it is very loud. If the motor is still loud while unattached, it likely will need to be replaced. If the motor is not loud while unattached, you may have a clogged line.
Step6
Check the wiring and voltage if your pool pump is turning on and off frequently. The installer might have used the wrong voltage or wired the pump incorrectly. If the wiring seems all right, check to make sure the pump's vents aren't blocked. Blocked vents could cause the pump to overheat, which will require repair.
