Method for operating a dishwasher

Abstract

A method for operating a dishwasher is provided. During a first phase, the dishwasher is operated with a first fluid quantity that is heated by a desorption process of a drying material. The first fluid quantity is increased to a second fluid quantity by adding a third fluid quantity that is stored in the drying material. During a second phase, the dishwasher is operated with the second fluid quantity. The first and second fluid quantities are circulated by a circulation pump during the first and second phases, respectively. The circulation pump is operated at a rotational speed that is higher during the second phase than during the first phase.
