Abstract
A dishwasher is provided having a dishwashing container and a filter system for cleaning dishwashing liquid. The filter system includes a foam volume and the filter system and the dishwashing container are communicated with one another such that at least some of the dishwashing liquid can be discharged from the dishwashing container in association with a washing cycle of the dishwashing machine to the foam volume for passage of the discharged dishwashing liquid through the foam volume. Dishwashing residue contained in the dishwashing liquid is at least partially absorbed or retained by the foam volume such that the fine-grained dirt particles can be filtered out of the dishwashing fluid, a resoiling of the dishwashing fluid or the items to be cleaned can be minimized and the dishwashing result can be improved.
