Samsung Eco Bubble WF 1602 W5V - Displays the code "Sud"

Despite the use of non-foaming powder, the "Sud" code appeared - an excess of foam, so I cleaned the filter, as well as the drain hose, dispenser and pressure switch. In addition, twice without laundry at 95 degrees and the program came to an end with no problem. When the washing machine is loaded with the batch and the centrifugation step is reached, the code reappears and the washing machine stops even though the washing machine is not visible.
Is it possible that someone can meet with such a case, and what else you can check here.

Problem solved. It turned out that you need to check the outflow from the drum more closely, because in the intake pipe there was a very tightly squeezed sock that behaved like a thick filter, which in the water washed quite well so the defect did not reveal itself. That made me mislead.
The sock during the washing had to be pulled between the drum and collar.
Maybe this advice will be helpful to someone. I close the subject.
