Abstract

The invention relates to a dishwasher, in particular a domestic dishwasher (1), comprising a control device (2) for carrying out a dish-washing cycle for washing a load, a washing chamber (7) for receiving the load during the washing cycle and a circulation pump (22) for circulating a cleaning fluid (S) which is in the washing chamber (7). Said control device (2) comprises a concentricity-monitoring unit (25) for testing the concentricity of the circulation pump (22), and a power signal (LS) which corresponds to the electric power absorbed by the circulation pump (22) is fed to said concentricity-monitoring unit (25). Said concentricity monitoring unit (25) comprises a filter arrangement (43) with a band pass ratio for generating a filtered power signal (GS) and an evaluation arrangement (44) which is mounted downstream from the filter arrangement (43) for evaluating the filtered power signal (GS).
