System with a dishwasher, method, and computer program product

A system, comprising:

• a dishwasher including a washing chamber;
• a sensor unit designed to detect a time curve of at least one sensor signal of a washing liquor and to output the detected time curve of the at least one sensor signal;
• a memory unit designed to store the time curve of the at least one sensor signal;
• an ascertaining unit designed to ascertain a temporal functional value based on the time curve of the at least one sensor signal;
• 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 temporal functional value.

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 a time curve of at least one sensor signal of a washing liquor;
• storing the time curve of the at least one sensor signal;
• ascertaining a temporal functional value based on the time curve of the at least one sensor signal;
• and
• carrying out with the control device a specified action as a function of the analysis result.
