Jandy VS FloPro 1.85 THP Variable Speed Pool Pump MECH-06 Error Fix: Pump Lid O-Ring Deterioration

The pump strainer lid O-ring is stretched, flattened, or cracked — a deteriorated lid O-ring allows air into the pump and causes loss of prime, air bubbles in the strainer pot, and reduced flow; remove the lid, inspect the O-ring for cracks, flat spots, or permanent deformation; clean the O-ring groove in the pump housing of any debris or old lubricant; lubricate the O-ring with silicone-based pool O-ring lubricant (never use petroleum-based products which destroy rubber); replace the O-ring if visibly damaged; Jandy pump lid O-rings should be inspected seasonally
