What to do if my Pentair Pool Products Timer shows a Regen Failure?
- MMatthew ThompsonJul 28, 2025
If your Pentair Pool Products Timer displays a Regen Failure, it means the system hasn't regenerated for over 99 days (or 7 days if set to Day-of-Week). To fix this, start a Manual Regeneration to clear the error. If it's a metered system, ensure it's measuring flow by running water and checking the display. If no flow is measured, check the meter cable and its function. In Master Programming, confirm the unit is correctly configured, including system capacity, day override, and meter settings. For Day-of-Week systems, ensure at least one day is set ON. Adjust settings as needed.
