Possible Causes

Corrupted internal settings, Incompatible firmware configuration, Incorrect user programming causing conflicts, Power interruption during setup

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before performing any hard resets if recommended by Pentair.

Steps to resolve configuration errors:

  • 1. Review user programming: Check all programmed speeds, schedules, and external control settings. Remove overlapping or conflicting schedules.
  • 2. Restore factory defaults: Using the keypad, follow the Pentair SuperFlo VS manual to reset the pump to factory default settings. Reprogram only essential speeds and schedules.
  • 3. Power cycle: After resetting, turn the breaker OFF for 1–2 minutes, then back ON. Verify if E09 clears.
  • 4. Check for firmware notes: Consult Pentair technical bulletins or support to see if your model has known firmware issues that require an update or replacement drive.

If E09 persists after a factory reset and proper programming, the control board may be defective and the drive assembly may need replacement.
