It’s frustrating to have a pool pump not working properly. To help, here is a comprehensive guide on troubleshooting tips for your pool pump not working. We’ll walk you through seven helpful tips to get you back up and running in no time.

1. Check for Power Disruptions

Make Sure the Pool Pump is Getting Power

There are a few easy steps to determine if the pool pump is getting power. First, make sure the power is on and that the fuse or circuit breaker has not tripped. If the power is on, unplug the pump and look inside the power cord for frayed wiring or loose connections. If the power cord or switch appears to be connected securely, plug your pump back in and switch it on.

Check the Timer

If the pump is off, check the timer to make sure it’s set to the proper timing. If the timer is set to on mode instead of auto, you won’t have power flowing to the pool pump. Change the settings of the timer so that it is set to auto, and then power cycle the pump.

Test the Voltage and GFCI

If the pool pump is still not working, you may need to test the voltage and the GFCI. The voltage reading should be between 110 and 240 volts. If it is within this range, then you can move on to the next step. If it is not, you should replace your pump with one that has the correct voltage.
If your voltage is fine, then you should test the GFCI to see if it has tripped. If the GFCI has tripped, it should be reset, and then the pool pump should start up again.

2. Check the Intake and Outlet

Inspect the Intake

The intake valve is responsible for allowing water flow into the pump. To check the intake valve, first turn off the power to the pump. Then, take off the lid of the pump strainer and check for debris, debris build-up, or a clogged or damaged strainer basket. If there is any debris, remove it and clean it before re-installing it.

Inspect the Outlet

The outlet valve works by allowing the water to return back to the pool after running through the pump. To make sure the outlet valve is working properly, look for any clogs or blockages in the pipe leading back to the pool. If there are any clogs or blockages, remove them and clear the pipe before turning the pump back on.

Check for Leaks

It is also important to check for any leaks around the intake and outlet valves. If there are any, turn off the pump and fix the leak before proceeding.

3. Verify the Water Level

Fill the Pump With Water

The first thing to do when troubleshooting your pool pump is to make sure there is enough water in the pump basin. If the water level is lower than the intake, the pump will not be able to draw in any water, causing it to not work properly. If the water level is low, you should fill it up with a garden hose before turning the pump back on.

Check the Pressure Gauge

The pressure gauge is another important part of the pump system. If the pressure gauge is not reading properly, the pump may not be able to draw in enough water to properly circulate it. If the pressure gauge is low, simply adjust the pressure gauge to a higher reading.

Monitor the Water Level

Once you’ve verified that the pressure is right and the pump is full of water, it’s a good idea to monitor the water level to make sure it doesn’t drop too low. This will help you avoid the pump from running dry and damaging the motor.

4. Check the Filter System

Clean the Filters

In order for your pool pump to work efficiently, you have to make sure the filter system is in good condition. If you have a cartridge filter, you should check for any clogs or debris build-up, and then clean it. If you have a DE filter, you should backwash it to remove any dirt and debris.

Check the Filter Lid

After cleaning the filter, you should also check the filter lid to make sure all of the gaskets are secure and none of the O-rings are worn or damaged. If the lid is not secure, the pump will not be able to run at full capacity.

Check the Pressure Gauge

After checking the filter lid, you should also check the pressure gauge to make sure the pressure is normal. If the pressure is high, you may need to backwash the filter again. If the pressure is low, it may indicate that the filter is clogged, and you may need to replace the filter.

5. Inspect the Impeller

Check for Impeller Obstructions

The impeller is a key component in the pump, and if it is damaged, it will cause the pump to not work properly. To make sure the impeller is in good condition, you should look for any obstructions or foreign objects in the housing. If you find anything, you should remove it and then clean the impeller before re-installing it.

Check for Worn Impeller

If the impeller appears to be in good condition, the next step is to inspect it for any wear and tear. If the impeller is worn or damaged, you will need to replace it. If it is intact, you can just re-install it and continue to troubleshoot the pump.

Check the O-rings

If the impeller looks okay, you should also check the O-rings for any cracks or damage. If these are worn or cracked, they will need to be replaced.

6. Replace the Pump if Needed

What to Look for in a New Pump

If the pool pump is still not working after troubleshooting, you may need to replace it. When looking for a new pump, it’s important to look for one that is energy efficient and has the correct voltage for your pool. You should also check for any warranties or reviews before purchasing a replacement.


Once you’ve purchased a new pump, it’s time to install it. First, you should turn off the power to the old pump and remove it. Then, install the new pump according to the manufacturer’s instructions. Make sure all of the connections are secure, and the lid is on tight.

Testing the Pump

Once the pump is installed, you should turn on the power and test it to make sure it is working properly. If the pump is not working properly, you should check all of the wiring and connections to make sure they are secure.

7. Get Professional Help

Know When To Call A Professional

If you are still unable to get your pool pump working, it may be time to call a professional. Make sure to get a few estimates and pick a reputable professional to do the job for you. They should be able to diagnose the problem and perform any repairs or replacements that are needed.

Be Prepared For Repairs and Replacements

When getting ready for a professional to come repair or replace your pool pump, make sure to have all the materials and tools needed on-hand. The professional will also need access to your pump, so you may need to have someone available to help them move it if necessary.

Post-Repair Testing

Once the professional is done with their repairs or replacements, it’s a good idea to test your pool pump one more time. Make sure to fill the pump with water and check the pressure gauge to ensure the pump is working properly.

Final Words

Troubleshooting your pool pump can be a daunting task, but it can be done successfully with some basic knowledge and the right tools. Check for power disruptions, inspect the intake and outlet, verify the water level, check the filter system, inspect the impeller, replace the pump if needed, and know when to call a professional. With these seven troubleshooting tips, you should get your pool pump running smoothly in no time.
