Possible Causes
Worn circulation pump bearings, Blocked impeller, Air lock in circulation line, Undersized or failing capacitor (if external)
How to Fix / Troubleshooting
Safety: Turn off power at the breaker before servicing the circulation pump.
- Bleed air: Loosen the union on the circulation pump slightly to release trapped air until water flows steadily, then retighten.
- Check for debris: Remove the pump wet end cover (if accessible) and inspect the impeller for hair, scale, or debris. Clean carefully and reassemble.
- Listen for bearing noise: Restore power and listen to the pump. Grinding or squealing indicates worn bearings and the pump should be replaced.
If P3 persists after clearing air and debris, replace the Hanscraft circulation pump to restore reliable operation.
