A dishwasher is provided with a washing container for receiving items to be washed by the dishwasher, a circulatory pump for circulating a rinsing liquid into contact with items received in the washing container, and a comminution device for comminuting rinsing residue. The comminution device and the circulatory pump are operatively interconnected in a manner such that the comminution device is at least temporarily driven by the circulatory pump. As a result, the comminution device can be driven in a simple and efficient manner, enabling the dishwasher to be produced at low cost and also increasing the reliable operability and easy maintenance thereof.
