1, can not start. Check that the wire connector is securely connected and that the switch contacts are tight. If there is an open circuit or poor contact, it should be repaired.
2, can not absorb water. The reason is that there is air or water in the pump body. Remedy: first press the water up, then fill the pump with water, then turn it on. At the same time, check whether the check valve is tight, and whether the pipeline or joint is leaking. If air leakage is found, apply lubricant or blend paint at the joint after tightening, and tighten the screw. Check the oil seal ring of the pump shaft. If the wear is serious, replace the new one.
3. The motor is overheated. Check the wiring and switch for short circuit, check the impeller and impeller cover, motor stator and rotor for friction, and remove obstacles in time.
4. Insufficient traffic. This is caused by too high a lift, too long a pipe or a right angle bend in the pipe. The lift should be adjusted to shorten the line or change the bend of the line. At the same time, the filter and the blockage of the line must be checked and removed.
