6. Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| La pompe ne démarre pas | No power, tripped breaker, motor overload, faulty wiring. | Check power supply, reset breaker, allow motor to cool, inspect wiring (call electrician if needed). |
| La pompe ne s'amorce pas | Low water level, air leak in suction line, clogged skimmer basket, closed valve. | Ensure adequate water level, check for leaks, clean skimmer basket, open all valves. |
| Débit réduit | Clogged filter, dirty skimmer basket, air in system, impeller obstruction. | Clean filter, clean skimmer basket, check for air leaks, inspect impeller for debris. |
| Bruit/vibrations excessifs | Cavitation (air in pump), worn bearings, loose mounting. | Check for air leaks, ensure proper water flow, inspect motor (professional service recommended). |
