Question
Is it permissible to use a dishwasher on Passover after replacing the dish trays, without koshering the body itself? Since there is always sixty times the water against the chametz, and the emission from the utensils is considered nat bar nat [as ruled in Shulchan Aruch, TNB].
Answer
Hello
Regarding Passover, where the prohibition is in any amount, having sixty or nat bar nat does not help.
In practice, the instruction is not to kosher a dishwasher even from meat to dairy, because it is impossible to reach the level of boiling that is effective for hagalah.
