Possible Causes

Failed internal motor position sensor, Damaged motor windings, Loose internal motor harness, Drive firmware incompatibility or corruption

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker and confirm with a meter before any disassembly.

Steps to address motor feedback errors:

  • 1. Power reset: Turn the breaker OFF for several minutes, then restore power and attempt to start the pump. Sometimes transient faults clear with a reset.
  • 2. Listen for abnormal sounds: If the motor hums, jerks, or vibrates without reaching speed, immediately shut it off. This indicates improper commutation or winding issues.
  • 3. Inspect for moisture and corrosion: Check the motor and drive interface area for signs of water ingress or corrosion on connectors (if accessible). Moisture can damage internal sensors.
  • 4. Verify correct programming: Ensure the pump is not being driven by incompatible external automation commands. Reset to factory defaults if recommended by Pentair documentation.

Because the motor feedback circuitry is internal to the SuperFlo VS motor/drive, field repair is not practical. Persistent E06 typically requires replacement of the motor and drive assembly.
