Why does my Pentair Water Pump show ERR 2?
- JJonathan LewisAug 22, 2025
The ERR 2 error on your Pentair Water Pump indicates that the controller power does not match 50 or 60 Hz. To resolve this, disconnect and then reconnect the power. If the problem persists, you may need to obtain a controller or AC transformer that is appropriate for your power frequency.
