Why Does My Hayward Pool Pump Start Then Shut Off?

Are you tired of your Hayward pool pump starting up only to shut off a few seconds later? This can be a frustrating problem that can prevent you from enjoying your pool during the hot summer months. There are several reasons why your pool pump may be behaving this way, and in this article, we’ll explore some of the common causes and potential solutions.

Clogged Impeller

One of the most common reasons for a Hayward pool pump to start and then shut off is a clogged impeller. The impeller is responsible for drawing water into the pump and pushing it through the filter system. Over time, debris such as leaves, twigs, and other pool debris can get stuck in the impeller, preventing it from turning properly. When this happens, the pump will start up and then shut off as it tries to move water through the clogged impeller.

To fix this problem, you’ll need to shut off the power to the pump and remove the pump basket and impeller cover. Use a small brush or toothbrush to clean any debris from the impeller, being careful not to damage it. Once you’ve cleaned the impeller, reassemble the pump and turn it back on to see if the problem has been resolved.

Faulty Motor or Capacitor

If your impeller is clean and your pump still starts up and shuts off, the problem may be a faulty motor or capacitor. The motor is responsible for driving the impeller, so if it’s not working properly, the pump won’t be able to move water through the system. Similarly, the capacitor provides an electrical charge to the motor, so if it’s not functioning, the motor won’t be able to start up.

To diagnose this problem, you’ll need to test the motor and capacitor with a multimeter. This is a specialized tool that measures electrical current and can help you determine if either of these components is faulty. If you find that the motor or capacitor is not working properly, you’ll need to replace them to fix the problem.

Low Water Flow

Another reason why your Hayward pool pump may start up and then shut off is low water flow. If your pool’s water level is too low, or if there’s a blockage in the plumbing system, the pump may not be able to move water through the system properly. This can cause the pump to shut off as a safety measure to prevent damage to the motor and impeller.

To fix this problem, check your pool’s water level and make sure it’s high enough for the pump to function properly. You should also check the plumbing system for any blockages, such as debris or leaves. If you find a blockage, remove it and try starting the pump again.

Conclusion

If your Hayward pool pump is starting up and then shutting off, there are several potential causes. By checking your impeller, motor and capacitor, and water flow, you can diagnose and fix the problem. If you’re not comfortable working on your pool pump yourself, consider hiring a professional pool technician to help you. With the right knowledge and expertise, you can get your pool pump running smoothly and enjoy a refreshing swim all summer long.
