How to Fix / Troubleshooting

Safety first: Turn off power and allow the motor to cool before handling.

  • Clear vents: Remove leaves, dirt, and debris from the motor cooling vents and surrounding area.
  • Check filter and valves: Clean the filter and ensure all valves are open to reduce system head pressure.
  • Verify voltage: Confirm the motor is wired for the correct supply voltage per the Hayward nameplate.
  • Consider shading: If the pump is in direct sun, provide a ventilated shade structure to reduce ambient temperature.
