The drum washing machine makes a loud noise, like knocking at the door. Why?

Too many clothes are washed and dehydrated at one time. When the drum rotates at high speed, it will produce greater centrifugal force, and the washing machine will have greater vibration and jitter, and at the same time, it will have greater noise. If used for a long time, it will damage or damage the mechanical mechanism of the washing machine. The solution is to appropriately reduce some clothes that are put into the washing machine for washing and dehydration at one time.
