A pool pump, no matter what brand it is, will eventually run into trouble because of the combination of heat, vibration, and moisture. These three factors coupled with daily use will eventually lead to problems that will need to be troubleshot down the line. And as a shameless plug, this is why pump warranties are as important as the features of a pump when considering a pool pump purchase! Now, with that out of the way, let’s proceed with the guide!

Pool Pump Power Problems1.1 Pool Pump won’t power upYou flip the switch and instead of the comforting (and sometimes annoying) roar of the pump, you’re greeted with silence. Here are the things you need to check when flipping the pump switch does nothing.
If everything checks out and your pump isn’t still powering up then it might be time to avail the warranty on your pool pump or to get a new one from Mr Pool Man’s online pool shop! 1.2 Pool Pump Immediately Shuts off after turning onYou turn on your pump, it slowly hums then roars into life and after a few seconds, nothing, eerie silence. A problem like this is usually indicative of an overload in the electrical system or a failing capacitor.
1.3 Pool Pump Randomly shuts off after a few minutesThe pump is working properly, you’re about to jump into the pool, and all of a sudden your pump suddenly shuts off. If this happens, the first thing you should check is the motor itself. Be careful when checking because it might be super hot. If it is hot, then that’s indicative of your pump’s motor overheating and that’s your pump’s thermal overload protecting your motor from overloading. To fix it, scroll down below to our section dealing with an overheating pool pump. Another reason could be if you’re not using a dedicated switch or timer for your pump and it’s wired directly to your breaker. Circuit breaker switches are not designed to be used as on-off switches and they will wear out faster than normal. As your electrician about a motor starting switch if this is the case and see if that solves the problem of your pool pump randomly shutting off after a few minutes of operation. Strange sounds coming from the pool pumpIf you’re a longtime pool user, you probably would have gotten used to the sound of your pool pump by now and any deviation from the “normal” noise will be quite noticeable. 2.1 Humming sounds coming from the pump and it won’t turn onThere can be two reasons for a pool pump to hum and not start properly. One problem is easily fixed and one will require tinkering with your pool pump, so let’s hope that it’s the first problem and not the second one.
2.2 Screeching or roaring sounds coming from the pool pump while operatingAnother problem that pool owners face is loud (not normal loudness) noises coming from the pool pump. There are different kinds of loud noises that commonly happens to pool pumps with problems and here’s what each of them means.
2.3 Loud “vibrating” noises coming from the pumpVibration in your pool pump is normal to a certain extent because of all the moving parts but only to a certain extent. If it starts to become noticeable or louder than usual then you may need to check the following things with your pump.
It is very important to reduce vibrations as much as possible because vibrations can cause damage not only to your pool pump, but to all of the plumbing attached as well. Vibrations can loosen your couplings, and if the vibrations reach a certain point, they can even affect the other components of your pool pumping/filtration system as well. Pool Pump Flow ProblemsIdeally, your pool pump should only be sucking in water consistently but for those situations where you have pool pump flow problems, it’s best to know how to identify them so you can fix them as soon as they start to prevent them from causing more problems down the line. 3.1 Pool pump is sucking in airIf your pool pump is sucking in air instead of water then the problem is usually located at the suction side of your pool.
3.2 Water flow from the pool pump is lowLow water flow from the pump could either be a suction-side problem or a return-side problem. We’ve already covered suction-side problems in the previous section so you can check those. If those don’t resolve the issue of low water flow then it’s time to check the pressure-side of the pump for any obstruction.
3.3 Pump basket does not fill up with waterThis is a very simple problem that can cause a lot of headaches down the line. If you leave your pump in this condition then it can lead to cavitation, surge, and even to your pump’s motor burning out. The fix is actually quite easy, all you need to do is to prime your pool pump and you should be good to go. Now if you’ve successfully primed your pump but the water in your pump basket compartment still drops and you’re back to square one, check your pump lid’s o-ring for debris or damage. Miscellaneous Pump ProblemsHere are some other pump problems that don’t fit into the other categories and can be considered symptoms or warning signs of bigger problems to come. 4.1 Pool pump loses primeIf your pool pump randomly loses prime but recovers, it’s a sure symptom of a leak or a blockage on the suction side. If your pump recovers prime on its own, then the leak or the blockage isn’t enough to fully impede the flow of water to your pump, but it’s getting there! Unlog your pool lines, check your pump lid o-rings for damage, check for leaks, and ensure that your water levels are where they’re supposed to be! 4.2 Pool pump is running hotPool pumps generate heat but they should never run too hot! How hot is too hot? Well, at full load, you should still be able to touch the motor end of the pump without burning yourself. Take note, touch, not hold. But once it gets to the searing hot point, then there’s definitely something wrong with your pump. Here are some possible causes of a searing hot pool pump:
4.3 Pool pump is leakingNow this is different from the leaks that we’ve discussed earlier. If water is leaking from the pump itself then you have a very big problem on your hands. The most common pump leak is from the connection point in between the pump body and the motor. This signifies a failure on your mechanical seal. Failure of the mechanical seal, if you’re lucky, will just cause water to leak to the ground beneath your pool pump. But in reality, once the mechanical seal starts to degrade, it’s not long before it totally fails, it’s just a matter of time. Once water bypasses the mechanical seals and flows into your pump motor, it’s game over. So if your pump itself is leaking then don’t delay, replace your mechanical seal immediately! Extending the life of your pool pumpNormally, a pool pump should last anywhere from seven to ten years and a properly maintained pool pump should last more than that! To extend the life of your pool pump here are some things to keep in mind.
ConclusionHopefully this troubleshooting guide helped you identify and treat pool pump problems as they pop up! While we suggest that you try and fix minor pool pump problems, anything major like a mechanical seal failure or a motor burnout, you should also take into consideration your pump’s age. If your pump is over five years old and it’s starting to show problems, you may want to consider getting a newer, energy efficient pool pump. Our reasoning for this is simple, time makes fools out of us all, and your pool pump is no exception. Once parts start degrading, it will only be a matter of time before the other components will start to fail as well. Getting a new pump will save you headaches down the line and you’re covered with a new warranty Do you have any questions about this topic or the featured products? No worries, we're here to help!

Please validate your form with reCAPTCHA. Why is my above ground pool pump not pulling water?It could be something blocking it, a dirty pool filter, or too much air in the system. If there's something blocking your pump's suction, check your filter gauge. If it's 10psi above the normal reading, clean your filter. This will reduce pressure and reset your pump's flow.
Why is my pool filter not pulling water?The most common reason for low or no flow is that the baskets are full of debris. By checking and emptying both the skimmer basket (by the pool) and the pump basket (inside the pump) will free up the water flow, allowing the system to fully 'prime' and function at full capacity.
Why is my pump not pulling water?Not enough water is running through the pump system
Your check valve may have failed, or it's been installed incorrectly. If neither of those are the cause, your pump may simply be air bound. Or, it might be bound by something that's been caught in the impeller. A sight inspection can give you the answer.
How do I get water to flow through my pool pump?The most common reason for low or no water flow is your skimmer and/or pump baskets are full of debris. By checking and emptying both the skimmer basket (by the pool) and the pump basket (inside the pump), this will help free up the water flow, allowing the system to fully 'prime' and function at full capacity.
