6. Troubleshooting
This section addresses common issues you might encounter with your ECO-FLO EFLS15P pump.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump runs but no water flows | Not primed, air leak in suction line, clogged suction line, low water level. | Ensure pump is fully primed. Check all suction line connections for leaks. Clear any obstructions. Verify adequate water source. |
| Pump leaks at motor/pump connection | Loose bolts, damaged shaft seal. | Check and tighten all bolts. If leak persists, the shaft seal may need replacement. Contact support for assistance. |
| Pump does not start | No power, incorrect voltage, motor issue. | Check power supply and circuit breaker. Verify voltage setting (115V/230V). Consult a qualified electrician if motor issues are suspected. |
| Reduced flow or pressure | Clogged impeller, partially closed valve, excessive lift. | Inspect and clean impeller. Ensure all valves are fully open. Verify pump is within recommended operating parameters for lift. |
