Hayward PowerFlo pump runs but there is no water flow; pump basket does not fill with water.

Safety first: Turn off the pump before opening the lid or valves.

• Check pool water level: Ensure the water level is at least halfway up the skimmer opening so the skimmer does not suck air.
• Clean baskets: Empty the skimmer basket(s) and the PowerFlo pump strainer basket. Debris can restrict flow and prevent proper priming.
• Inspect lid O-ring: Remove the PowerFlo strainer lid, clean the O-ring and sealing surface, and apply a thin coat of pool-safe silicone lubricant. Replace the O-ring if it is cracked or flattened.
• Check suction fittings: Inspect the suction-side union or hose connection at the PowerFlo pump for cracks or looseness. Tighten unions by hand plus a small additional turn; replace cracked fittings or hoses.
• Prime the pump: With the lid off, fill the PowerFlo strainer housing with water from a hose, reinstall the lid, open all suction valves, and start the pump. It may take 1–3 minutes to fully prime.
