Abstract
A household dishwasher includes a first spray arm having a first spraying circle, a second spray arm having a second spraying circle which overlaps with the first spraying circle, and a synchronization facility configured to adapt a rotational speed of the first spray arm to a rotational speed of the second spray arm, or vice versa. The synchronization facility includes a first magnetic field allocated to the first spray arm and a second magnetic field allocated to the second spray arm, with the first magnetic field and the second magnetic field having a same polarization, so that the first magnetic field and the second magnetic field repel one another during operation of the household dishwasher to thereby prevent contact between the first spray arm and the second spray arm during a rotational movement of the first spray arm and the second spray arm.
