The detector can be an inductive sensor (160) that detects an indicating member (141) of the washing basket. The washing basket can comprise one or several indicating members, for enabling a more reliable detection. A method of operating such a dishwasher (100) comprises the steps of automatically detecting what type of washing basket (140) is placed in the dishwasher, and then controlling the water pressure and granule addition according to what washing basket was detected. A system comprises an above dishwasher and an above washing basket.
