We accidently washed a dairy cup in a fleishig dishwasher. There was no milk in the cup and it is not expensive china. Rather it is everyday dishes (earthenware). What do we do with the cup? The dishwasher?
If the dishwasher had soup in it when used then all is fine. Dishwasher and Cup are Kosher. It should not be done in the first place. Rabbi Dov Lior
