| Fault phenomena | Cause analysis | Mixing and removal method |
| Insufficient flow or no water output | 1. Incorrect impeller rotation | 1. Adjust the direction of impeller rotation |
| 2. Check whether the valve is open and intact | 2. Inspection, maintenance, and elimination | |
| 3. The pipeline impeller is blocked | 3. Clear out clutter | |
| 4. Spinning speed is too low | 4. Inspect electrical equipment and circuits | |
| 5. Excessive head | 5. Modify the pump or reduce the head | |
| 6. The medium being pumped has a relatively high density | 6. Dilute with water to reduce concentration | |
| 7. The medium has relatively high viscosity | 7. Reduces viscosity | |
| 8. Damaged sealing ring (at the rim) | 8. Replace | |
| Operation is unstable | 1. Imbalanced impeller | 1. Send to the manufacturer for replacement or calibration |
| 2. Bearing damage | 2. Replace | |
| The pump cannot start | 1. Lack of appearance | 1. Inspection and repair of the circuit |
| 2. The impeller is stuck | 2. Remove debris | |
| 3. Winding, joint, or cable disconnection | 3. Use an ohmmeter to inspect and repair | |
| 4. Stator windings are burned out | 4. Repair or replace windings | |
| 5. Electrical control failure | 5. Repair or replace | |
| Excessive current | 1. Low operating voltage | 1. Adjust the operating voltage |
| 2. Pipelines and impellers are blocked | 2. Clearing pipeline and impeller blockages | |
| 3. The height or viscosity of the liquid being pumped is relatively high | 3. Change density or viscosity | |
| 4. Heads used are too low | 4. Reduce traffic flow. Increase head | |
| Low insulation in electrical units | 1. Leakage at the power terminal of the cable cable | 1. Tighten and press the Leum mother |
| 2. Cable damage | 2. Replace | |
| 3. Mechanical seal wear causing leakage | 3. Replacement | |
| 4. Each type 0 sealing ring fails | 4. Replace | |
| 5. One machine casing is corroded by medium and leaks | 5. Repair |
