Possible Causes

Prolonged overload operation, Blocked ventilation, Failed start capacitor (on single‑phase DAB pumps), Shorted windings

How to Fix / Troubleshooting

Safety first: Immediately turn off power at the breaker. Do not attempt to restart the pump. Smoke indicates a serious fire risk.

Steps to check:

  • Allow to cool: Let the motor cool completely before inspection.
  • Inspect visually: Look for melted insulation, burnt smell, or discoloured windings through ventilation slots.
  • Check capacitor: On capacitor‑start DAB pumps, test or replace the start/run capacitor if swollen or leaking.
  • Replace motor: In most cases of burning smell or smoke, the motor must be replaced. Do not reuse a burnt motor.
