Abstract: A heating means installed in a pump for heating water during pumping has a tubular cylindrical holder that defines a heating chamber for the water. On the outside of the holder, a plurality of heating conductor tracks are connected together in series. The heating means is configured for operation of the pump in the horizontal state, such that its longitudinal axis extends horizontally. In this horizontal state, the heating means has a residual water level as a horizontal plane that lies roughly in the lower third. Apart from two heating conductor tracks, the heating conductor tracks extend below this residual water level, while said two heating conductor tracks extend above the residual water level. In the absence of cooling water on the inner surface of the heating chamber, they can overheat more quickly and be locally destroyed as an emergency safety device before the entire heating means is at risk of overheating.

The connection device is attached at the contact fields with the contact feet and is electrically connected thereto. Additional electrical insulation is arranged between the connection device and the outside of the carrier. This can be, for example, one of several individual insulating layers that together form the entire insulating layer.

The two connection contacts are electrically disconnected from one another and make electrical contact with the single heating element or all of the heating elements of the heating element group for connection to a current supply or as a power connection. An effective width of all of the heating elements within a common heating element group is greater than an effective length of the single heating element or all of the heating elements of this common heating element group between the two connection contacts.

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. Here, the pump has an outlet in the end region of the pump chamber at an axial spacing from the impeller. Heating elements which have a decreasing power output with regard to the area power output in the axial direction of the pump toward the outlet are arranged on the pump chamber wall. An input of energy into the pump chamber can thus be varied and in the process adapted depending on a turbulent or laminar flow.

At least one of the connection areas is connected to a controller for evaluating a leakage current as current flows through the dielectric layer, and the heating element is connected to measuring means for monitoring a heating conductor current through the heating element. Both the leakage current and the heating conductor current are monitored over time and faults can be identified if there are conspicuous changes.
