Possible Causes

Tripped breaker at pool sub-panel, Loose or disconnected supply wiring, Failed internal drive power supply, Open thermal fuse in motor

How to Fix / Troubleshooting

Safety first: Treat all wiring as live until proven otherwise with a meter. Turn off the breaker before opening any covers.

  • 1. Check breaker and switches: Verify the pool pump breaker is ON and not tripped. Reset if necessary. Confirm any external timer or switch feeding the SuperFlo is in the ON position.
  • 2. Test for voltage at the pump: With the breaker ON (use caution), use a multimeter to confirm correct voltage at the pump terminals. If no voltage is present, the issue is upstream (breaker, timer, wiring).
  • 3. Inspect wiring connections: Turn power OFF, then open the wiring compartment on the motor. Tighten all lugs and check for burned or broken wires. Repair or replace damaged conductors.
  • 4. Check display and drive: If correct voltage is present but the display remains blank, the internal power supply or drive board is likely failed. There are no user-serviceable parts inside; replacement of the drive/motor assembly is typically required.

If you are not comfortable working with live electrical circuits, contact a licensed electrician or pool professional.
