Abstract: A pump of a dishwasher has an integrated heating element, a pump chamber with an inlet and an outlet, a pump rotor inside the pump chamber and a drive motor, wherein the heating element and a temperature sensor are provided on a wall of the pump chamber. For measuring a calcification of the pump chamber it is filled with water and then the pump rotor rotates for mixing the water in the pump chamber without transporting water out of the pump chamber. The temperature of the water in the pump chamber is measured with the temperature sensor as a starting temperature, and then the heating element is activated to heat the water in the pump chamber while the temperature of the water in the pump chamber is measured. Then the heating element is deactivated and the maximum temperature of the water during the heating duration or directly afterwards is determined. A temperature relation between the maximum temperature and the starting temperature of the water is calculated.

Abstract: A heating device for a hob has a flat rectangular carrier with an outer edge, two heating elements which each have a heating conductor and which together form a heating area and which are fastened on the carrier, wherein each heating element defines a partial heating area, and the partial heating areas are situated inside the rectangular shape of the carrier. The heating elements and their partial heating areas can be operated independently of one another. The partial heating areas of the heating elements do not intersect. A first partial heating area is rectangular and extends, by way of at least one of its outer sides, to the outer edge of the carrier and runs parallel in relation to the outer edge. A second partial heating area covers the portion of the rest of the carrier which is left free by the first partial heating area. Various configurations of heated areas can be achieved owing to the independent operation.

Abstract: In a method for the production of a heating device, comprising a support that is curved along one direction and at least one flat thick film heating element disposed thereon, the support and/or the heating device itself are processed from a tube, in particular a circular-cylindrical tube. For that purpose a tube wall is severed in one direction which does not exclusively have a peripheral direction component so that the support is not a circumferential tube. The thick film heating element can be applied before or after the severing.

Abstract: A pump for a dishwasher is configured as an impeller pump having a central water inflow to a rotating impeller for conveying the water in the radial direction out of the impeller into a pump chamber which surrounds the impeller in a ring-like manner and has a heated pump chamber wall on its outer side.
