Hello, I have a 3/4 Hayward Pool pump that starts, runs quiet then will stops after 30 seconds and I see some smoke coming from the front of the motor
Thank you for contacting Inyo. Is this a new pool pump or motor? I ask because the motor can shut down and smoke if the incorrect voltage is applied.
If this is an existing pump, the motor capacitor may have failed. What is the catalog or model number of the motor?
Below are a couple sources for troubleshooting the motor.
