Pump runs but water appears cloudy or dirty despite normal operation.

Safety first: Turn off pump before servicing filter.

• Step 1 – Increase run time and RPM: Adjust the Pentair variable‑speed schedule to run longer at a moderate RPM to improve turnover.
• Step 2 – Clean or upgrade filter: Backwash or clean the filter. Consider upgrading to a larger Pentair filter if undersized for pool volume.
• Step 3 – Check for bypasses: Ensure any bypass valves (e.g., heater bypass) are not diverting too much flow away from the filter.
• Step 4 – Eliminate air leaks: Fix suction‑side air leaks that can reduce effective filtration.
