Can you wash clothes with najasat via the washing machine, (hadse akbar) sperm etc.
In the name of Allah, the most Beneficent, the most Merciful
Impurities (najasat) are of two types, visible and invisible.
Visible impurities become clean by washing/removing the impurity.
The invisible impurity becomes clean by repeated washing until the person washing feels that the item is now clean. (Hidaya, VOL1, P77-78) The jurists have stated that this can usually be achieved by washing the item thrice. The ruling of washing thrice is mentioned in Fatawa Hindiya. (VOL1, P41-42)
As the process of washing clothes in the washing machine involves several washes and rinses, impure clothes can therefore be washed via the washing machine. The clothes will become clean as long as no visible impurity is still present after the wash.
Allah knows best.
