A dishwashing machine including a comminution device and a method for comminuting residue in the dishwasher. The comminution device at minimal manufacturing costs, makes it possible to easily comminute the coarse contaminants or residue accumulating during the rinse cycle in the dishwashing machine, flush it out of the dishwasher and at the same time reduce the danger of clogging the sieve(s) placed in the dishwasher. The comminution device preferably is actuated by the lye pump of the dishwashing machine. In this manner the comminution device is actuated easily and efficiently, which both enables cost-effective manufacture of the dishwashing machine, and improves its operating safety and ease of maintenance. In the process the rinse residue can first collect during the rinse cycle in uncomminuted form on the floor of the rinsing container and only then be comminuted when the washing liquid is pumped out and flushed out of the dishwashing machine.

An apparatus allows monitoring the formation of scale. The apparatus makes it possible to determine the degree of water hardness or a tendency of the degree of water hardness to change over time and to take measures for adjusting the desired degree of water hardness accordingly. A translucent or transparent element has two end surfaces, at least one element emitting an optical signal, and at least one element receiving an optical signal. The element emitting the optical signal and the element receiving the optical signal are directly adjacent to the end surfaces of the transparent element, and the end surfaces are disposed such that they remain free of scale build-up at all times.

A device and a method for detecting deposits on surfaces includes a body having a surface on which deposits occur and influence reflection properties of the surface to electromagnetic radiation. A transmitter transmits electromagnetic radiation to the body and a detector detects the presence of the deposits at the surface. The detector measures electromagnetic radiation received from the transmitter after reflection at the surface. Preferably, the device and method are used in a liquid-conveying machine, particularly, a washing machine and/or a dishwasher. Particularly, light is introduced into the light-guiding body to detect the presence of the deposits. The light is internally reflected by the surface and is guided to a sensor. If deposits occur on the surface, the deposits affect the light-reflecting properties of the surface, and the affect is detected by the sensor.
