Abstract

A dishwasher includes a control device controlling a dishwashing cycle for cleaning items to be washed, a dishwashing chamber for the items to be washed, an inlet valve for controlled filling the washing chamber with washing liquid, and a circulating pump for circulating the washing liquid in the dishwashing chamber. The inlet valve is opened during a primary filling phase having a duration sufficient to fill the dishwashing chamber with a nominal amount of washing liquid and allowing the circulating pump running to run concentrically at a rated speed. A concentricity monitoring unit performs a concentricity check at the end of the primary filling phase to ascertain whether the circulating pump is running concentrically at the rated speed. The filling sequence is terminated when the circulating pump is running concentrically, whereas the filling sequence is continued when the circulating pump is not running concentrically.
