A dishwasher, wherein a duct system has a function describing a pressure difference in dependence on the rotational speed of the circulating pump and having a lower rotational speed range in which the pressure difference changes at most in proportion to the rotational speed of the circulating pump and an upper rotational speed range in which the pressure difference changes more than in proportion to the rotational speed of the circulating pump; and wherein the control device has a first rinsing program in which the circulating pump is operated at a normal cleaning rotational speed for normal cleaning of the rinsing stock and a second rinsing program in which the circulating pump is operated at an intensive cleaning rotational speed higher than the normal cleaning rotational speed and lying in the upper rotational speed range for intensive cleaning of the rinsing stock.
