Pools are fantastic in the summer, but when the pool pump suddenly stops working, it can be frustrating. The first thing you have to do is turn the power back on.
More often than not, this will fix your pool pump problems. You can still troubleshoot your pool pump problem if you’ve already tried that. Here are some tips to try to solve your pool pump not working issue.
Pool Pump Not Working Troubleshooting Tips
The Pool Pump Is Not Turning on Properly
One of the most common pool pump problems is when it simply will not turn on. If this happens, consider these possibilities:
- If your pool pump isn’t turning on when you flip the switch, it may be a simple problem with your wiring.
Make a visual inspection of your fuse panel for blown fuses. Afterwards, examine your connections to ensure that nothing is loose or broken. If you’re not quite sure what you’re doing, let an electrician take a look at it instead.
- If your pool motor gets jammed and turns off after it starts, this could be an overloaded circuit.
Make sure that you have the proper voltage for your pump. Additionally, check the motor’s vents to ensure that nothing is obstructing the fan.
- If the pump’s motor shaft is not working correctly, it is possible that the motor is lodged with debris.
- If the pump turns on but isn’t functioning at full capacity and you hear a buzzing noise, the capacitor may be the problem.
Problems with capacitors should be addressed by a professional, so contact them right away.
The Pump Runs but on Low Flow
- If the pump runs but on low flow or sometimes does not circulate the water, check to see if any of your jets are clogged. Clean the jet if necessary.
- If the pump is still running on low flow, turn off the main pool shut off valve and then turn it back on. This will let the water pass through the pressure side without running through the filter first.
- If your pump is still running slow after all of this, it could be that there is a blockage someplace in the line or an air pocket somewhere in the system not allowing water to get past it.
The Pool Pump Is Leaking or Making Strange Noises
A pool pump is bound to get stuck or leak once in a while. So here are the most common pool pump problems you’ll see when this happens:
- If your pump is leaking, it could be that there is a crack on the pump casing.
This will lead to water in the motor and cause it to overheat. Apply silicone sealant around any cracks to fix this issue.
- Strange noises on your pool motor mean something is hitting the fan blades while they are spinning.
This could be anything from dirt or sand swirling in the water to leaves caught on the fan. Clean the blades and/or fan guards to fix this issue. - If your pump is making loud noises while it is running, there could be debris in the system.
Clean out your filter housing if necessary.
The Pump Turns on for a Split Second and Turns Off
- If the pump turns on for a split second but doesn’t continue to run, this could be a fuse problem.
Look at the fuse box and check for a blown fuse. If you can see water in your circuit after sticking a flashlight into it, then you may have a short in the circuit extending from one point to another.
- If your pump turns on for several cycles but then turns off, you may be running your pump too hot.
So make sure that there’s no debris in the system and that there isn’t any water in the motor housing.
The Pump Is Leaking Water
- If you have a leaking pump, check for any worn seals that need replacement.
Inspect the O-rings in the impeller housing, the thread sealant, and the shaft seal.
- If you suspect an O-ring is leaking, bend the O-ring all the way around and search for cracks.
- If you notice any cracks, this indicates that the O-ring has dried up and needs replacements.
- If there are no cracks on the O-ring, just apply O-ring lubes to help maintain a better seal and last longer.
The Pool Pump Is Sucking in Air
This pool pump problem can happen for numerous reasons, including;
- A pump lid that has come loose
- A minimal or large crack in the pool pump
- A faulty thread sealant
- Old O-rings and gaskets
- Air leak is present in the suction line
- A faulty valve stem
- A plumbing problem on the suction pump.
Look for defects, such as holes, leaks, or faulty connectors, and fix those by replacing parts.
Tip: "If you can't find the air leak in your pump, apply shaving cream on the possible areas for a leak. If there's a leak, it will suck the shaving cream, leaving an indent." - Matt Giovanisci
Water Isn’t Entering the Pump Basket
- If the water is not properly filling up the pump basket, it could also be because of a dirty or clogged filter or pump basket.
- If you clean the filter and pump basket and are still experiencing problems, you should begin looking for the source of the leak.
In addition, make sure there is sufficient water in your skimmer. If the water level is less than halfway up the skimmer, air could be the source of the problem.
Moreover, inspect the O-ring on the basket lid to ensure a proper seal.
Signs That Your Pool Pump Is About to Sign Off
A pool pump doesn’t last forever, but it can last for about 8-10 years with proper maintenance. But what are the signs it’s about to sign off? Here are a few:
You Have Constantly Had Low Readings From Your Filter Pressure Gauge
To check, connect your pool cleaner (if you have one) to see if it’s working properly. If it is, but you still see low readings, try removing the pressure gauge and cleaning the threads. If that doesn’t work, you need to replace the pump. If this happens more often, then it’s likely that your impeller is starting to wear out.
Pool Pump Leaks More Often Than Not
If you’ve done everything you can to stop the pump from leaking, and they continue to occur regularly, the seal on the motor shaft may be completely worn out.
The good news is that this is cheap and you can easily replace it without purchasing a new pump. But if you’re already replacing the motor shaft and the water is still leaking from the pump even when it’s turned off, it’s an indicator that the seal on the motor shaft has given up.
Pool Pump Loses Its Prime
If your pump continues to lose suction despite troubleshooting all possible causes, it has most likely reached the end of its useful life. Its parts could be totally worn, and it’s time for you to get a new pump.
Bottom Line
Many of the issues you may have with your pool pump may be simply resolved if you know where to look. However, do not hesitate to contact a professional for assistance or even just some pool advice.
