Loud knocking during the drying Samsung Dryer
The customer complained of a loud knocking noise during drying. It turned out that the pulley idler at some point jammed from the lint caught in it and the belt began to worn it. After some time, the roller began to spin again and due to the fact that the belt all the time fell into this groove at high speed was a loud knock during working. We replaced the pulley idler in time because it could lead to its failure and a belt break.
