Why Is My Pool Pump Running in Reverse?

Published in Pool Maintenance 1 min read

Your pool pump shouldn't run in reverse. If you hear a strange noise or see your pool water circulating backward, this usually indicates a problem with your pump's motor or wiring.

Here are some common reasons why your pool pump might be running in reverse:

  • Reversed Wiring: The most likely culprit is reversed wiring. If the electrical wires connecting to the motor are accidentally switched, the motor will spin in the opposite direction.
  • Faulty Motor: A damaged motor can also cause reverse operation.
  • Incorrectly Installed Impeller: The impeller, which moves the water, might be installed backward.

To fix the issue, you should:

  • Check the wiring: Make sure the wires are connected to the correct terminals on the motor.
  • Consult a professional: If you're not comfortable working with electrical components, it's best to call a qualified electrician or pool service technician. They can diagnose the problem and make any necessary repairs.
