Title
(DE) WASSERFÜHRENDES HAUSHALTSGERÄT
(EN) WATER-BEARING HOUSEHOLD APPLIANCE
(FR) APPAREIL MÉNAGER À CIRCULATION D'EAU
Abstract
(DE)
Die Erfindung betrifft ein wasserführendes Haushaltsgerät (1), insbesondere Geschirrspülmaschine (2), dem während mindestens eines Füllschritts Flüssigkeit zuführbar ist und das wenigstens eine Laugenpumpe (6) zum Herausfördern von Flüssigkeit aus dem wasserführenden Haushaltsgerät (1) und eine Überfüllungsschutzeinrichtung (11) zur Verhinderung eines zu hohen Wasserstands in dem wasserführenden Haushaltsgerät (1) aufweist. Dabei ist vorgesehen, dass die Überfüllungsschutzeinrichtung (11) zur Erfassung von wenigstens einem Betriebsparameter der Laugenpumpe (6) ausgebildet ist und nach dem Füllschritt bei Vorliegen einer aus dem wenigstens einen Betriebsparameter herleitbaren Fehlfunktion der Laugenpumpe (6) die Durchführung eines weiteren Füllschritts verhindert. Die Erfindung betrifft ferner ein Verfahren zum Betreiben eines wasserführenden Haushaltsgeräts (1).
(EN)
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).
(FR)
L'invention concerne un appareil ménager (1) à circulation d'eau, notamment un lave-vaisselle (2), auquel un liquide est cédé lors d'au moins une première étape de remplissage et qui comprend au moins une pompe de vidange (6) pour évacuer le liquide de l'appareil ménager (1) à circulation d'eau et un dispositif de trop-plein (11) pour empêcher un niveau d'eau trop élevé dans l'appareil ménager (1) à circulation d'eau. A cet effet, le dispositif de trop-plein (11) est conçu pour détecter au moins un paramètre de fonctionnement de la pompe de vidange (6) et, au terme de cette étape de remplissage, empêcher l'exécution d'une autre étape de remplissage en cas de dysfonctionnement de la pompe de vidange (6), dysfonctionnement imputable audit au moins un paramètre de fonctionnement. L'invention concerne également un procédé pour faire fonctionner un appareil ménager (1) à circulation d'eau.
