According to the Shafi'i madhhab, is it possible to clean a thing from najis by washing in a washing machine?

According to the Shafi'i madhhab, standing water does not purify a thing from najis, but on the contrary, it becomes najis if it comes into contact with it, and its volume is less than about 216 liters. It turns out that if I put a thing stained with najis in the washing machine for washing, it will not be cleaned, but on the contrary will make all the things that are washed with it unclean? It's just that I used to wash things in the washing machine that had an invisible najis on them without any signs (volume, color, taste, smell).
