Abstract (en)
[origin: WO2022002557A1] The invention relates to a dishwasher (1), in particular a domestic dishwasher, comprising a controller (150) for running a wash program for washing washware arranged in a wash chamber (4) of the dishwasher (1), a first spray unit (112) and a second spray unit (122) which can selectively be supplied with a wash liquor (F) via a pump device (140) in order to form a respective wash zone, and an intensive spray device (132) which is paired with the first (112) or the second spray device (122) and can be brought into an activated state or a deactivated state by means of a switch valve (133). The controller (150) is designed to detect a first pump flow (I0) while the first spray device (112) is being supplied with wash liquor (F) and to detect a second pump flow (I1, I2) while the second spray device (122) is being supplied with wash liquor (F) in order to form a current differential value (ΔI0) on the basis of the detected first (I0) and second pump flow (I1, I2) and in order to ascertain a current switch state of the intensive spray device (132) on the basis of the current differential value (ΔI0), a number of stored earlier differential values (ΔI1 – ΔI8), and a specified class differential value (K), wherein the controller (150) is designed to adapt the wash program on the basis of the ascertained current switch state.
