Pool pumps and filters should operate noiselessly, if properly installed and maintained. However, over time --- or if improperly maintained --- pool pump motors can become loud. A loud pool pump motor is not only unpleasant to hear, but often the loud pump is not cleaning the pool water properly. If your pool pump motor is making loud noises, it's time to troubleshoot the filtration system to find out what's causing the noise.

Skill level:


  1. 1

    Check the pool pump and filter base to see if it was installed on level ground. If the filter system is sitting on an uneven base or on ground that's not level, the internal moving parts of the pool pump will cause the entire filter and the motor to vibrate. Sometimes solving the noisy pump is as simple as securing the base for the filtration system.

  2. 2

    Clear the pump basket and skimmer basket. If these two baskets are filled with debris, the pool pump motor must work twice as hard to suction the water from the pool and push it through to the filter. When the motor is overworked, it will make noise. Keeping the basket areas clean will reduce pump motor noise.

  3. 3

    Examine the pool pump impeller. To examine the impeller, turn off the filter, unplug the pump and open the pump basket lid. Pull out the pump basket and reach your fingers down through the tube leading from the pump basket towards the impeller. Touch the impeller to see if it's clogged with debris or if it is wobbly. Too much debris or a wobbling impeller will cause the pump to sound loud. Remove the debris if it's dirty. If the impeller is wobbly, it may need adjustment or replacement.

  4. 4

    Replace the bearings. If you hear a whining sound in the motor, it's time to replace the bearings. This is an intricate process, so it is recommended that you take it to a technician familiar with the inner workings of a pool pump motor.

  5. 5

    Raise the pool water level. If it has fallen below mid height of the skimmer faceplate, it is possible that air is getting into the pool filtration system. When air gets into the pump, it disrupts the pump's vacuum environment needed to filter the water. It puts more of a strain on the pool pump, causing it to sound louder as it works harder. Adding water to the pool will resolve the problem.

Tips and warnings

  • Most pool pump motors last about eight years. If your motor is older than eight years, it may be time for replacement.
  • Unless you are very familiar with the inner workings of a pool pump motor, do not attempt to dismantle and replace parts. Take it to a qualified technician.
