| fault phenomenon | failure cause | elimination methods |
| 1.No power supply or one or two phase power supply is needed | Check all phases of power supply and restore power supply | |
| 2.Poor contact of ac contactor and burning of coil | Repair or replace contactors | |
| can not start | 3. The power switch is not closed, malfunction or damaged | Close the switch and replace it if the power indicator does not turn on |
| 4. Thermal relay trip or damage | Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started | |
| Water level is too low | Put water in the sink | |
| The motor burned | Repair or replace the motor | |
| 1.Line is loose | Check wiring and tighten connectors | |
| 2.Frequency converter malfunction | Check the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting. | |
| The manual is normal | 3The frequency converter is damaged | Repair or replace |
| Automatic transmission failure | 4.Pressure switch damage | Repair or replace |
| 5The pressure transmitter is damaged | Repair or replace | |
| 6.Switch failure | Repair or replace | |
| Pump non - suction pressure gauge pointer to beat violently | Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument | Check pipeline and bottom valve, refill water diversion. Tighten air leakage |
The pump consumes too much power | Too much flow, impeller wear | Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow |
