Pool Pump Not Working? Here's What to Check

1. Clean the Filter
Start by ensuring your filter is clean and the pressure gauge isn’t reading excessively high (30 PSI or more). A dirty filter can cause pump cavitation (air entering the pump), as the pump struggles to pull water.

2. Pump Basket and Suction Leaks
Properly clean the pump basket and check for suction leaks. Inspect the pump O-ring for damage and clear any blockages in the impeller. These steps can help keep your pump running efficiently.

3. Understand the Pump and Motor
Remember, the pump and motor are separate parts bolted together. Issues with the pump occur before the motor connections.
•    If the circuit breaker trips when the motor turns on: The motor may be burned out and will need replacement.
•    If the motor struggles to start but eventually does: The starter capacitor is likely failing. Replacing it should resolve the issue.
•    If water leaks from the connection between the motor and pump: The pump seal has likely failed. This is a $5 part that’s easy to replace but crucial to address promptly. If left unfixed, it can cause rust and motor failure.

4. Impeller Jams
A twig, rock, or debris can jam the impeller. When this happens, the motor may turn on, buzz, and then shut off.
Solution:
Turn off all equipment at the circuit breaker. Carefully check if the impeller spins freely. If it doesn’t, remove any debris obstructing it.
