Pentair Pentair IntelliFlo3 VSF Variable Speed Pool Pump IMPELLER CLOG Error Fix: Impeller Obstruction

Debris has entered the pump volute and is caught in or around the impeller, restricting water flow and potentially causing the impeller to jam. Common debris includes leaves, acorns, small rocks, pine needles, and small toys. Symptoms include reduced flow, unusual noise (grinding, rattling), and potential E01 (overcurrent) or E08 (priming error) codes. Turn off the pump. Open the pump lid and remove the strainer basket. Look into the impeller eye (the opening at the bottom of the volute) for visible debris. Some debris may require removing the pump volute from the motor to access the impeller directly.
