A dishwasher includes a dishwasher interior for washing items to be washed with washing liquor. Arranged at a lower end of the dishwasher interior is a pump sump for collecting the washing liquor, and a sensor is arranged in the pump sump for outputting a sensor signal as a function of a presence of washing liquor at the sensor. A control apparatus configured to carry out a washing program selected from a number of washing programs is designed to determine a malfunction of a component of a hydraulic assembly as a function of the sensor signal and of a current operating state of the dishwasher.

Dishwasher, method for operating a dishwasher, and computer program product

A dishwasher includes a pump device operated by a pump current for supply of washing liquor to a first spray device via a first hydraulic arrangement for providing a first washing zone and to a second spray device via a second hydraulic arrangement for providing a second washing zone. A third spray device is connected to one of the first and second hydraulic arrangements for providing an intensive washing zone. In a first switching state, the third spray device is isolated from the one hydraulic arrangement, and in a second switching state the third spray device is connected to the one hydraulic arrangement. A control device determines a current switching state of the third spray device as a function of a difference between the pump current when washing liquor is supplied to the first hydraulic arrangement and when washing liquor is supplied to the second hydraulic arrangement.
