Fault Phenomenon Failure Cause Elimination Methods
  1. No power supply or one or two phase power supply is needed
Check all phases of the power supply and restore it if necessary.

 
  2. Poor contact of AC contactor and burning of coil
Repair or replace the contactor.

 
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
Fill the sink with water.

 
  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 3. The frequency converter is damaged Repair or replace.
Automatic transmission failure 4. Pressure switch damage Repair or replace.
  5. The 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.
