Hayward PowerFlo pump motor housing shows visible rust and corrosion on the exterior.

Safety first: Turn off power before touching the motor.

• Identify moisture source: Look for leaking unions, fittings, or valves near the PowerFlo that may be spraying water onto the motor. Repair leaks.
• Improve protection: Install a weather-resistant cover or small shelter over the pump and motor, ensuring adequate ventilation.
• Assess severity: Surface rust can be cleaned and treated with rust-inhibiting paint, but deep corrosion near electrical connections or end bells may require motor replacement.
