Abstract: A method for operating a water-conducting household appliance having a storage container which is connected by means of an overflow outlet in a liquid-conducting manner to a washing compartment and having a pump which is connected in the liquid-conducting manner to the washing compartment. The method includes starting the pump; filling the storage container with a liquid; monitoring a first operating parameter associated with the pump after the pump has been started; and terminating the filling of the storage container with the liquid when the first operating parameter reaches a predefined threshold value and/or the first operating parameter exceeds a predefined fluctuation range.

Abstract: A dishwasher and a method for operating a dishwasher having a washing receptacle; at least two spraying devices located within the washing receptacle; a reversing device; a drive in functional connection with the reversing device in order to bring the reversing device into different positions; and a circulation pump which, depending on a set position of the reversing device, conveys liquid to at least one of the at least two spraying devices. The method includes controlling the drive such that the reversing device assumes a predefined starting position; and controlling the drive such that, based on the predefined starting position, the reversing device assumes a specific position.

Abstract: A dishwasher with a multi-step filter system includes a coarse filter and a micro filter for cleaning the rinsing solution and also includes a lye pump and a circulatory pump. The dishwasher also includes a comminutor arranged in the path of the flow downstream from the coarse filter for remains contained in the rinsing solution.

Abstract: A circuit arrangement is provided for protecting from overheating a heating element whose resistance value is a function of its temperature. The circuit arrangement includes a power supply, a switch, and a switch control circuit, a current sensor providing a signal proportional to the current flowing through the heating element, and a first scaling device whose output provides a signal proportional to the supply voltage of the heating element. An evaluation circuit compares the difference signal determined by a first detector having an output that provides a difference signal formed from the signals of the current sensor and the first scaling device with a reference signal and the switch control circuit can be switched from a conducting state when the switch control circuit is in a first state to a non-conducting state when the switch control circuit is in a second state.

Abstract: A water-conducting domestic appliance having a drain pump, a controller to activate the drain pump, and a water safety switch that has a first switch position to react to escaping water, wherein the water safety switch is connected to the controller. If a fault causes water to escape, the water safety switch switches into the first switch position so as to connect the controller to an electrical mains.

Abstract: A method for operating a dishwasher that has a washing container; at least two spray devices disposed inside the washing container; a circulating pump to deliver liquid to the at least two spray devices; a first drive to drive the circulating pump; and a reversing device; wherein, based on a position of the reversing device, the circulating pump delivers the liquid to one or both of the two spray devices. The method includes adjusting the position of the reversing device and detecting the current position of the reversing device based on an operating parameter assigned to the first drive.
