Abstract: A method for detecting a leak, having at least the following steps: a) capturing a flow volume of a liquid through a liquid line during a multiplicity of liquid removal processes; b) comparing the flow volumes of the liquid in the respective liquid removal processes with an alarm value; c) outputting an alarm signal if the flow volume of the liquid in a liquid removal process exceeds the alarm value; d) adapting the alarm value on the basis of a frequency of the occurrence of the flow volumes of the liquid in the liquid removal processes above an adaptation value.
