Embodiment Construction

[0016] The drawing shows a schematic illustration of a domestic appliance 1 containing water, which is designed as a dishwasher 2 . The dishwasher 2 has a work area 3 in which items to be cleaned or washed (not shown) are placed. The items are here positioned on at least one shelf 4 which can be pulled out, for example, forwards from the workspace, that is to say out of the plane of the drawing. The working area 3 is also referred to as a wash container. A sump 5 is provided at the bottom of the working area 3 for collecting water or washing liquid introduced into the working area 3 . A drain pump 6 and a circulation pump 7 are connected to the sump 5 for fluid flow purposes. Fluid can be conveyed from the sump 5 towards the waste water connection 8 by means of the drain pump 6 . The drain pump 6 can also be used to pump fluid out of the sump 5 or the working area 3, whereby the drain pump 6 also acts as a drain pump. A circulation pump 7 can be used to supply fluid from s...

Abstract

The invention relates to a water-bearing household appliance (1), in particular a dishwasher (2), to which a fluid can be added during at least one filling step and comprising at least one lye pump (6) for delivering fluid from the water-bearing household appliance (1) and an overfilling protection device (11) for preventing too high a water level in the water-bearing household appliance (1). The overfilling protection device (11) is designed for capturing at least one operating parameter of the lye pump (6) and prevents performing a further filling step after the filling step if a faulty function of the lye pump (6) is present that can be derived from the at least one operating parameter. The invention further relates to a method for operating a water-bearing household appliance (1).

Description

technical field [0001] The invention relates to a water-containing domestic appliance according to the preamble of claim 1 . Background technique [0002] A water-containing domestic appliance, such as a dishwasher, is supplied during the filling step with the fluid required to operate the appliance. In this process, the fluid is supplied in particular into the working area of ​​the domestic appliance, for example into a washing container of a dishwasher. At least one drain pump is also provided, which can be used to pump the fluid out of the household appliance again. In order to prevent overflow of water caused by an excessively high water level in the domestic appliance and thus water loss in the environment of the domestic appliance, the domestic appliance has an overfill protection device. This prevents excessive water levels from occurring. For example, the overfill protection device can have a bottom groove in which a water level sensor is arranged. When the water...
