Abstract (en)

The invention concerns a method for the operation of a dishwasher with program control, in which the program steps are variable depending on the degree of opaqueness of the washing solution. The cleaning effect is optimised with a minimum expenditure of time and energy in that a first program structure can be selected for easily cleaned domestic soiling and a second program structure can be selected for burned-on and/or dried-on domestic soiling, in that the degree of opaqueness of the washing solution is measured by means of an optical sensor according to transparency and foam formation, in that in the first program structure at least the washing duration is varied in the program steps and in that in the second program structure the washing solution is heated to a defined temperature, at least in pre-washing.
