Pentair Pentair IntelliFlo VSF Variable Speed Pool Pump LID ORING LEAK Error Fix: Pump Lid O-Ring Air Leak

Error code LID ORING LEAK on the Pentair Pentair IntelliFlo VSF Variable Speed Pool Pump means: Pump Lid O-Ring Air Leak. The O-ring that seals the pump strainer lid to the pump housing has dried out, cracked, compressed flat, or become pinched, allowing air to enter the system. Symptoms include visible air bubbles in the pump basket (visible through the clear lid), difficulty priming, and intermittent flow. Inspect the O-ring for cracks, flat spots, or deformation. Clean the O-ring groove of debris. Apply a thin coat of silicone-based O-ring lubricant (never petroleum-based). Replace the O-ring if damaged (approximately $8-15). Over-tightening the lid can also cause the O-ring to extrude and fail.
