Abstract

In a method for operating a dishwasher, in particular a household dishwasher, a washing program is performed from a number of washing programs, with the washing program including a sub-program step of pre-washing and a sub-program step of cleaning that follows the sub-program step of pre-washing. The sub-program step of pre-washing includes supplying water into a washing compartment of the dishwasher to provide a washing liquor, dispensing a predetermined amount of a cleaning agent into the washing liquor, and circulating the washing liquor and applying the washing liquor to items to be washed arranged in the washing compartment, while a heater for heating the washing liquor is inactive during the sub-program step of pre-washing. The sub-program step of pre-cleaning includes heating the washing liquor to a predetermined temperature, and circulating the heated washing liquor and applying the heated washing liquor to the items in the washing compartment.

         23 . The method of  claim 14 , further comprising reducing a pump rotational speed during at least one of the sub-program steps of pre-washing and cleaning compared to a washing program, in which the cleaning agent is not dispensed into the washing liquor during the sub-program step of pre-washing, but rather during the sub-program step of cleaning. 
     
     
         24 . The method of  claim 14 , further comprising reducing a duration of at least one of the sub-program step of pre-washing and the sub-program step of cleaning compared to a washing program in which the cleaning agent is not dispensed into the washing liquor during the sub-program step of pre-washing, but rather during the sub-program step of cleaning. 
     
     
         25 . A computer program product embodied on a non-transitory computer readable medium comprising commands which, when executed by a computer, cause the computer to carry out the method set forth in  claim 14 .
