Possible Causes

Overheating motor due to blocked ventilation, High ambient temperature, Overloaded pump (high head), Failing motor windings

How to Fix / Troubleshooting

Safety first: Turn off power and let the motor cool before touching it.

Steps to reduce overheating:

  • Improve ventilation: Clear debris from around the Jacuzzi motor and ensure adequate airflow.
  • Check for binding: Spin the shaft or impeller by hand to ensure it rotates freely.
  • Verify pump sizing: Ensure valves are not excessively throttled and that the system is not creating extreme backpressure.
  • Measure current draw: Have a technician measure motor amperage and compare to nameplate rating.

If the motor is drawing normal current but still overheating, internal winding damage may be present and the motor should be replaced.
