The dryer drainage pump noise big how should solve

Dryer generated by the impeller of pump of vacuum sucking up from below the water to high again, if no water in the pump body, not form a vacuum, the water does not come up, if the level is higher than the water pump, can use the irrigation ways to introduce the water pump body, or also need water.

In normal circumstances, when the drainage pump works, if there is no liquid in the dryer, the drainage pump is in no-load condition, and the noise is more normal than when the liquid is discharged. However, the noise is not very large, which causes the abnormal noise when the drainage pump works. The drainage pump itself is damaged. At this time, we need to take certain measures according to the specific situation to solve these problems.
