1. A system, comprising:
a dishwasher including a washing chamber;
a sensor unit comprising at least two of a member selected from a group consisting of a turbidity sensor, a conductivity sensor, a temperature sensor, and a filter soiling sensor, with each member configured to detect a time curve of a sensor signal of a washing liquor, wherein the sensor unit is configured to output the detected time curves of at least two sensor signals;
a memory unit designed to store the time curves of the at least two sensor signals;
an ascertaining unit designed to ascertain a temporal functional value based on the time curves of the at least two sensor signals, wherein the temporal functional value comprises at least two integral values, and wherein the ascertaining unit is designed to integrate the time curves of the at least two sensor signals to ascertain the at least two integral values, and wherein the ascertaining unit is further designed to ascertain a key figure based on the at least two integral values; and
a control device designed to carry out a washing program for washing washware in the washing chamber of the dishwasher and to carry out a specified action as a function of the ascertained key figure.
 
15. A method for operating a dishwasher which includes a control device for carrying out a washing program for washing washware arranged in a washing chamber of the dishwasher, said method comprising:
detecting time curves of at least two sensor signals of a washing liquor with a sensor unit comprising at least two of a member selected from a group consisting of a turbidity sensor, a conductivity sensor, a temperature sensor, and a filter soiling sensor, with each member detecting a time curve of a sensor signal of the washing liquor;
storing the time curves of the at least two sensor signals;
ascertaining a temporal functional value including at least two integral values based on the time curves of the at least two sensor signals by integrating the time curves of the at least two sensor signals to ascertain the at least two integral values;
ascertaining a key figure based on the at least two integral values; and
carrying out with the control device a specified action as a function of the ascertained key figure.
