  If your Intex swimming pool pump filter motor fails to start, ensure the line cord is plugged into a 3-wire outlet protected by a Class A Ground Fault Circuit Interrupter or RCD. Also, reset the circuit breaker; if it trips repeatedly, your electrical system might have a defect, so turn off the breaker and call an electrician. You can also let the motor cool down before restarting it.
