Troubleshooting
If you encounter issues with your SEAFLO 56 Series Portable Washdown Pump Kit, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | No power, incorrect wiring, or faulty switch. | Check 12V DC power source connection and polarity. Ensure the power switch is in the "ON" position. Verify power cord integrity. |
| Low or no water flow. | Clogged inlet strainer, air in the system, kinked hose, or low water source. | Clean the inlet strainer. Ensure the inlet hose is fully submerged and free of kinks. Prime the pump by allowing water to flow through before starting. |
| Pump runs but no water. | Loss of prime, air leak in inlet line, or dry running for too long. | Re-prime the pump. Check all inlet connections for air leaks. Ensure continuous water supply. |
| Water leaks from hose or connections. | Loose connections, damaged hose, or worn O-rings. | Tighten all quick connect fittings. Inspect the coiled hose for damage and replace if necessary. Check and replace O-rings if worn. |
