ABSTRACT:
A dishwasher is provided with a probe for measuring pH the value of a wash liquid. A corresponding wash program is run that is dependent on the pH value of the wash liquid measured by the probe. The wash program is selected from several programs stored in the program controls. The pH can be controlled by adding detergent as necessary. Extra functions can be selected by an operator.
