      If your Intex Water Pump filter motor fails to start, ensure the filter cord is plugged into a 3-wire outlet protected by a Class A Ground Fault Circuit Interrupter, or RCD. Also, try resetting the circuit breaker. If it repeatedly trips, there may be an electrical system defect, so turn off the breaker and call an electrician. Finally, allow the motor to cool down.
