Abstract

See full text

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.
