You were in a kosher household and in the absence of two dishwashers (Yes, i know of Jewish households that have two.) one will be set aside strictly for meat or dairy. There will also be seperate cabinets for identical set of dishes, one for dairy and one for meat.
If you were aware of this before you made the soup and then cleaned up afterward you may be on the hook.
It would seem that a rabbi could kasher the dishwasher however i'm not entirely sure, but he should be consulted.
By rabbinical law that dishwasher is no longer kosher.
