Is a blanket considered pure after being washed three consecutive times in an automatic washing machine, despite the smell of urine remaining in it? And does the automatic dryer become pure by the moisture of the clothes that enter it, and if it becomes pure, do the clothes then become impure? And if it does not become pure, how can it be purified when it does not have openings for water to be discharged?

The persistence of the smell of impurity does not matter if its removal is difficult and arduous.

The dryer does not become impure merely by doubt. If its impurity is certain, then it is purified by pouring water over it. The passage of wet clothes over it is not sufficient to purify it. If it would be damaged by pouring water over it, then wiping it, like smooth surfaces, is sufficient.

If the dryer is not purified, there is a difference of opinion regarding the transfer of impurity to the wet clothes that come into contact with it.
