why is my pool filter not turning on



Having a functional pool filter is vital for keeping your swimming pool clean and clear. It is designed to remove impurities and debris in the water, ensuring that it is safe and enjoyable for swimming. However, what happens when your pool filter is not turning on?

In this article, we will explore some reasons why your pool filter may not be turning on and how to troubleshoot the issue.

Sub-Heading 1: Power Supply

The first thing to check if your pool filter is not turning on is the power supply. Ensure that the filter is plugged in and that the socket is supplying power, look for any frayed cords, broken or loose connections, or power surges, which can damage the pool filter's motor causing the filter not to turn on.

Always check the breaker box to make sure the pool's breaker is on and not tripped, otherwise, resetting it will help solve the problem.

Sub-Heading 2: Timer Malfunction

One of the most common reasons why a pool filter is not turning on is a malfunctioning timer. Pool filters are usually set to a specific schedule when they should turn on and off. Ensure that the timer is set correctly and that the time of day and days of the week are accurate.

A timer's malfunction can cause the pool filter not to turn on, or the filter may turn on and off randomly. Replacing a timer is an easy solution, but always consult a professional pool technician for assistance.

Sub-Heading 3: Dirty Filter

If a pool filter is not turning on, it could be due to a clogged or dirty filter. A dirty filter can cause the motor to overwork, making it difficult to start. This issue can be fixed by performing routine maintenance on your pool filter.

Always clean your filter with the manufacturer's recommended chemicals, water, and temperatures. Follow the recommended schedule for replacing or cleaning your pool filter; failure to do so can cause potential damage to your pool filter system.

Sub-Heading 4: Leaking Water

A leaking pool filter system can cause various issues, including the pool filter not turning on. When water leaks into the pump motor, it can cause the motor to short circuit or become damaged over time. Always check the piping and pool filter housing for leaks that can develop over time.

A small crack or hole in a pool filter housing can permit water to seep into the motor. It will cause the motor to burn out, which can be costly and dangerous, requiring a new pool filter to be installed.

Sub-Heading 5: Faulty Motor

Finally, a faulty pool filter motor can be one of the most significant issues causing the pool filter not to turn on. The pool filter motor is responsible for powering the filter's operation, and when it becomes faulty, it can cause the entire filter to stop working.

Such an issue requires a professional repair technician's intervention to fix or replace the pool filter system's motor.


In conclusion, owning a pool comes with a responsibility to ensure that it is well-maintained and properly functioning. A pool filter that is not turning on can be a significant issue that can lead to other related issues. Ensure that you perform routine maintenance, check for power supply and timers, and consult a professional pool technician if required.
