Does washing clothes stained with a visible impurity, such as menstrual blood, in an automatic washing machine along with other clothes remove the impurity, or must the impure clothes be hand-washed before being put into the washing machine?

If impure clothes are placed in a small amount of water (less than two qullas) in a washing machine tub or a container, the water becomes impure, and the clothes remain impure. In fact, all the clothes placed with them become impure. These clothes are purified by pouring water over them until the impurity is presumed to have been removed, and certainty is not a condition. To wash impure clothes with others, they must first be purified from the impurity before being placed with the rest of the clothes in a small amount of water for cleaning.
