Abstract: A method is provided for operating a dishwasher (1) in the form of a batch dishwasher, which has a treatment chamber (2) for accommodating washware to be cleaned. Provision is made, during an adsorption phase, for air to be conducted out of the treatment chamber (2) through a sorption unit (41), which contains a reversibly dehydratable dry material, in such a way that the dry material absorbs moisture from the air stream, wherein the air is then returned to the treatment chamber (2). Provision is further made, during a desorption phase, for the dry material of the sorption unit (41) to be heated in such a way that moisture is desorbed from the dry material as steam. During the desorption phase, the sorption unit (41) is subjected to forced ventilation only to such an extent that recondensation of desorbed steam in the sorption unit (41) itself is effectively prevented.

Abstract: In order to reduce the fresh water or final-rinse liquid quantity necessary to clean items without impairing the effectiveness of the cleaning, it is provided that, during an adsorption phase, air is led out of the treatment chamber of the machine through a sorption unit such that moisture is absorbed from the air flow by a dry material, after which the air is fed back to the treatment chamber. During a desorption phase, the dry material is heated and air is led out of the treatment chamber through the heated dry material such that moisture is desorbed from the dry material and at least a part of the desorbed moisture is discharged as steam from the sorption unit. At least a part of the steam discharged from the sorption unit is led into the treatment chamber during a steam final-rinse phase.
