1, can not start. Check the electrical connector is solid connection, switch contact is tight. If open circuit or poor contact should be repaired. 2, can not absorb water. The reason is that there is air in the pump body or intake pipe. Remedy: First water pressure up, and then filled with water pump, and then boot. At the same time check the check valve is tight, piping, fittings leaks, such as found leakage, remove the joint at the joints coated with oil or paint, and tighten the screws. Check the pump shaft seal ring, such as serious wear and tear should be replaced with new pieces. 3, motor overheating. Check the wiring and the switch is shorted, check the impeller and the impeller cover, the motor stator and the rotor have no friction, promptly remove obstacles. 4, lack of traffic. This is because the head is too high, the pipeline is too long or the pipeline has a right-angle bend caused. Should adjust the head, shorten the pipe or change the curvature of the pipeline, but also must check and eliminate the clogging filter and pipeline.
