During the long process of operation, the pump will sometimes have some problems. Here are the common problems and how to fix them:
- Electric leakage pump :
- The cause of this phenomenon is that the wire connection of the motor winding is hit by the shell due to damage to the insulation. In addition, due to dampness of the motor winding or water, the same symptoms are observed.
- The remedy is to dry or repair the wire connection of the insulating or gene-coated tape .
- Electricity enters the pump but the machine is not working
- Curse: the machine has burnt starter coil or working coil, dry or punctured capacitor, power supply has lost phase, pump power float is broken, power supply is weak
- How to fix: need to rewind the motor winding when the coil is burned, replace the capacitor when the capacitor is dry or punctured. Fix the water float and power supply when the power system is out of phase or the float fails. The source voltage should be increased when there is insufficient power.
- The most common failure is the pump running well but no running water .
- Cause: There is no water entering the suction tube due to dehydration or water drying. There is no priming water in the pump chamber due to a open check valve. Pump seal is open. The suction line is open or punctured. The impeller is broken
- Remedy: Check the water source, replace the one-way valve. Prime more water into the pump chamber and run the machine again. Replace seal when the machine is open, replace the impeller

- The pump runs with a loud noise
- Cause: because the electric motor part bearings are greased dry or corroded and water gets in. In this case it often leads to fuse blown .
- How to fix: maybe little oil on the two ends of the shaft before replacing the new fuse and running the pump again , need cleaning, lubricating the bearings,
- The pump is running, the engine is hot
- Causes: engine capacity is too small, engine wire is shorted, industrial pump is stuck, source water is too weak
- Remedy: replace the motor with large capacity, rewind the coil, clean grease regularly. If the pump is newly purchased but hot phenomenon occurs, check the water supply line before and after the pump to see if it is blocked. If the pipe is not clogged, it is necessary to replace and repair the pipe
