Abstract
A unit for detecting an addition of a cleaning agent in a beverage dispenser, in particular in a coffee machine. In order to guarantee that a cleaning agent has been added when automatic cleaning is carried out, a measurement device is provided as well as a method of determining whether a cleaning agent has been added to the aqueous cleaning liquid. Whether a cleaning agent has been added to the aqueous cleaning liquid can be determined in dependence upon the measured conductivity and the measured electrical resistance of the cleaning liquid, respectively.
