Don’t let a broken pool pump ruin your summertime enjoyment!

An integral part of any swimming pool is the pool pump. It keeps the water in the pool clean and safe for swimmers by circulating water through the filtration system. The water in a pool can easily become contaminated and hazardous to use without a working pool pump. Regrettably, it occasionally happens for pool pumps to malfunction, leaving pool owners angry and unsure of what to do. In this post, we will examine the typical causes of pool pump failure and offer troubleshooting techniques to fix the problem.

5 Reasons a Pool Pump May Not Be Turned On

There are a number of possible causes for your pool pump not to be operating. Some of the most typical causes are listed below:

Electricity Supply Problems

A problem with the power supply is among the most frequent causes of pool pump failure. A blown fuse, a bad power cord, or a bad GFCI outlet could all be to blame for this. Check the power cable for any obvious evidence of damage, such as ragged wires or a damaged plug, to solve this problem. If the power cord seems to be in good shape, try plugging in another item to see if the outlet is functional. Replace the blown fuse or reset the GFCI outlet if the outlet isn’t working properly.

Circuit Breaker Trip

A circuit breaker trip is another frequent reason why a pool pump cannot operate. The pool pump is protected by the circuit breaker from electrical overloads that could harm it or possibly start a fire. The power supply to the pool pump will be cut off if the circuit breaker trips. Locate the circuit breaker panel and check for any breakers that are in the “off” position to troubleshoot this problem. If you come across a tripped circuit breaker, turn it back on to reset it.

Filter blockage or debris in the impeller

A pool pump may not operate due to a blocked filter or debris in the impeller. The filter may fill up with particles over time, limiting water flow and taxing the pump. Moreover, the impeller may become clogged with debris and become immobile. Remove the pump cover and shut off the pool pump’s power to begin troubleshooting this problem. Look for any obvious debris in the filter and clean it if necessary. Next, look for any obvious debris on the impeller and take out any that you find.

Defective capacitor or motor

The pool pump might not operate if the motor or capacitor is damaged. A damaged bearing, a broken seal, or overheating can all result in a bad motor. A damaged capacitor may make it impossible for the motor to turn on. Turn off the pool pump’s power and physically check the motor and capacitor for any obvious evidence of damage to begin troubleshooting this problem. If you see any damage, have the damaged parts fixed or replaced by a professional.

Broken or overheated wiring

A pool pump not working can also be caused by overheating or faulty wiring. A broken motor or a clogged filter might cause overheating, while animals chewing on the wiring or exposure to the elements can destroy it. Turn off the electricity to the pool pump and look for any obvious signs of damage to the wiring when troubleshooting this problem. If you see any damage, get the harmed wires repaired or replaced by a professional.

How to Fix a Pool Pump That Won’t Turn On

Now that we have gone over some of the reasons why a pool pump might not turn on, let’s take a look at some troubleshooting techniques to get your pump working again:

First, make sure the power is on:

When your pool pump won’t turn on, the first place to look is the power source. Double-check that the pump is plugged in and that the breaker has not tripped.

Examine the Engine:

If you think the motor is at fault, check it out for cracks or other damage. Possibly, if the motor is worn out or broken, it will need to be replaced.

Third, inspect the pump’s basket:

It is important to check the pump basket for damage or debris. If the basket needs to be cleaned or replaced, do so.

Observe the impeller:

Check the impeller for damage or foreign debris. If the impeller needs to be cleaned or replaced, do so now.

5. Double-check the timer/switch:

Inspect the timer or switch to ensure it is set correctly and operating properly.

6. Make sure the GFCI plug is working:

A GFCI outlet may be used to power the pool pump; in the event of an electrical failure, it will trigger and turn the pump off. If the plug needs to be reset, check it first.

Capacitor Testing No. 7:

An electric motor’s capacitor stores energy until it’s needed, giving the motor a jolt of power during startup. The pump might not turn on if the capacitor is malfunctioning. If the capacitor fails a multimeter test, it should be replaced.

Eighth, be sure the voltage is right:

The pool pump may not turn on if the power supply is inadequate. Check the voltage with a voltmeter and get in touch with an electrician if you need to.

9: Look for blockages:

In the case that water is not circulating through your pool, make sure the pump, suction lines, and return lines are all clear of debris. Clear away any obstructions so water can freely flow through.

Observe the pressure indicator:

When the filter system’s pressure gauge registers a high number, it could be because the system’s high pressure is preventing the pump from starting. If the pressure is too high, backwash the filter and try to restart the pump.

Advice for Avoiding Pool Pump Problems

These suggestions might assist you in avoiding typical pool pump problems. Keeping a well-functioning pool pump is essential for keeping your swimming pool clean and safe.

Routine Maintenance

The key to preventing problems with pool pumps is routine maintenance. This includes testing the motor and capacitor as well as cleaning the filter and inspecting the impeller.

Maintaining the Region Around the Pool Pump Clean and Debris-Free

Maintaining a clean and clutter-free environment around the pool pump might help avoid problems as well. Cleaning entails clearing the filter or impeller of any leaves, twigs, or other material.

Maintaining the pH balance of the pool’s water

Pool pump problems can be avoided by maintaining a balanced chemistry in the pool’s water. This entails frequently shocking the pool and preserving the right pH and chlorine levels.

Purchasing a Pool Cover

Purchasing a pool cover can also stop problems with the pool pump. An impeller or filter clog can be avoided by using a pool cover to keep debris out of the pool.


What causes my pool pump to hum but not turn on?

The majority of the time, a humming sound means that the motor is getting electricity but is unable to start. A damaged motor, a jammed impeller, or a defective capacitor are just a few possible causes for this.

Can I change the pool pump’s motor myself?

Pool pump motor replacement can be a challenging process that should only be performed by someone with electrical component repair skills. To avoid any safety risks, a professional should be hired.

How frequently should a pool pump be changed?

A pool pump’s lifespan might change depending on factors like usage and upkeep. A properly cared-for pump, however, can survive up to 10 years or longer.

Can a blocked filter prevent the pool pump from starting?

An increase in pressure brought on by a blocked filter may prohibit the pool pump from operating. Backwashing the filter can frequently resolve the problem.

Can a pool pump turn on by itself?

No, a pool pump needs to be manually activated using a switch or timer. Your pump should be checked by a professional if it suddenly starts operating. This could be a problem with the electrical wiring.


Pool owners may find it frustrating and even dangerous when their pool pump won’t operate. You may fix the issue and avoid other issues by comprehending the typical causes of pool pump failure, applying the troubleshooting techniques described in this article, and knowing the possible causes. Also, you can keep a healthy and secure swimming pool for you and your family to enjoy by adhering to the advice for preventing pool pump troubles.
