A device for determining a fill level of liquid within a suds tub of a washing machine, having a fill level sensor by means of which a pressure value generated by the liquid can be determined, the fill level sensor having at least one detection part disposed in a lower area of the suds tub that is covered by the liquid during the washing process. In one embodiment, an outcome amount associated with a total number of events is determined. An interface component can receive a portion of serialized data with transparent structure related to an application specification. The fine pattern is revised by forming an auxiliary pattern maintaining a first distance D1 from the second pattern.
