What does ERR3 mean on my Pentair AUTOTROL Performa 263 Control Unit and how do I fix it?
- RRobert PatelSep 12, 2025
If your Pentair Control Unit shows an ERR3 error, it means the camshaft rotated for more than 5 minutes trying to find the Home position. If the motor keeps rotating indefinitely, replace the following components in this order: the wire harness, the motor, the optical sensor, and finally, the controller.
