How to Fix / Troubleshooting

Safety first: Immediately turn off power at the breaker. Do not attempt to restart the pump until the cause is identified.

  • 1. Inspect motor exterior: Look for discoloration, melted plastic, or burn marks on the motor and drive.
  • 2. Check ventilation: Ensure motor vents are clear of debris and that the pump is not enclosed without airflow.
  • 3. Verify wiring and voltage: Have an electrician confirm correct wiring and supply voltage.
  • 4. Replace motor/drive: If burning smell or smoke originated from the motor, replacement of the motor and drive assembly is recommended; internal damage is likely.
