Possible Causes
Running PowerFlo pump dry for extended periods, Severe cavitation causing heat and friction, Blocked flow causing overheating in wet end, Incorrect replacement impeller not rated for pump
How to Fix / Troubleshooting
Safety first: Turn off power and drain the pump before disassembly.
- Remove motor and impeller: Separate the PowerFlo motor from the housing and attempt to unscrew the impeller from the shaft. Use proper tools and hold the shaft at the rear to avoid damage.
- Inspect impeller: If vanes are melted, warped, or cracked, replace the impeller with the correct Hayward PowerFlo model.
- Check for underlying issues: Determine why the pump ran dry or overheated (air leaks, closed valves, blocked lines) and correct those issues.
- Reassemble with new seal: Whenever replacing an impeller, also install a new mechanical shaft seal.
