Fault phenomena	Possible causes	Troubleshooting
1. The water pump does not discharge water	a. The inlet outlet valve is not opened, the inlet and outlet pipelines are blocked, and the impeller flow path is blocked. b. The motor is running in the wrong direction and the motor is missing phase. c. The suction pipe is leaking. d. The pump is not filled with liquid and there is air in the pump chamber. e. Inlet water supply is insufficient, Suction Lift is too high, and the bottom valve is leaking. f. The pipeline resistance is too large.	a. Check and remove obstructions. b. Adjust the direction of the Motor and tighten the Motor wiring. c. Tighten each sealing surface to remove air. d. Open the upper cover of the pump or open the exhaust valve to exhaust the Air. e. Shut down for inspection and adjustment (grid-connected water pipes This phenomenon is prone to occur when using a Suction Lift. ) f. Reduce pipeline bends and reselect the pump.
2. Insufficient water pump flow	a On 1 first. b. Pipes and impellers are partially blocked, scale is deposited, and valve opening is insufficient. c. Voltage is low and Speed does not meet the requirements. d. Impeller wear.	a. Press 1 first. exclude. b. Remove the obstruction first and readjust the valve opening. c. Voltage stabilization d. Replace the impeller
3. Power is too large	a. Use exceeding the rated flow b. Suction Lift is too high c. Pump bearing wear d. Improper pump selection	a. Adjust Flow and close the valve b. Lower the Suction Lift. c. Replace the bearings. d. Re-select the pump.
4. Noise and vibration	a. The pipeline support is unstable. b. Liquid mixed with gas. c. Cavitation occurs. d. Bearing vibration. e. Motor is overloaded and running hot.	a. Stabilize the pipeline. b. Increase the suction pressure and exhaust. c. Reduce the vacuum degree. d. Replace the bearing. e. To adjust, press 5.
5. Motor fever	a. Flow is too large and overloaded. b. Bump. c. Motor bearing is damaged. d. Voltage is low.	a. Close the outlet valve. b. Check and rule out. c. Replace the bearings. d. Voltage stabilization.
6. Water pump leaks	a. Mechanical seal wear. b. The pump body has sand holes or cracks. c. The sealing surface is uneven. d. The installation bolts are loose.	a. Replace. b. Welding repair or replacement. c. Trimming. d. Fasten.
