The dishwasher may include a rack positioned in a washing space and at least one nozzle that directs washing fluid into the washing space, a sump that receives washing fluid to be supplied to the washing space, and a filter device provided in the sump, including a first filter and a second filter. A driver rotates the first filter or the second filter so as to separate foreign materials from the filter device and prevent the filter device from clogging.
