Possible Causes

How to Fix / Troubleshooting
Safety: Turn off all power to the pump before removing covers.
- Inspect feedback harness: On Sta‑Rite variable‑speed pumps, locate the low‑voltage harness between the motor and drive. Ensure the connector is fully seated and free of corrosion or broken pins.
- Check for cable damage: Look for cuts, kinks, or rodent damage along the harness. Replace the harness if any conductors are exposed or broken.
- Secure strain relief: Make sure the cable is not being pulled tight by conduit or equipment movement. Re‑route if necessary to relieve stress on the connector.
- Reset and test: After reseating connectors, restore power and attempt to start the pump. If E07 returns, the internal motor sensor or drive logic is likely defective.
- Replace assembly as needed: Because the feedback sensor is integral to the motor, the typical repair is replacement of the complete motor assembly or the combined motor/drive kit specified by Pentair Sta‑Rite.
