How to Fix / Troubleshooting
Safety first: Turn off power and close valves before disassembling the pump.
- Clean baskets: Ensure skimmer and pump baskets are clean to maximize flow.
- Inspect impeller: Remove the pump housing and diffuser to access the impeller. Use a small tool to clear any debris from the impeller eye and vanes.
- Check impeller condition: If vanes are eroded or broken, replace the impeller with the correct Hayward part for your pump model and motor HP.
- Reassemble and test: Reinstall all components, open valves, and verify improved flow and filter pressure.
