Abstract

L'invention concerne un lave-vaisselle (10) qui est doté d'un réservoir de lavage (2) comprenant une partie d'ouverture (2a) destinée à recevoir de la vaisselle et une porte (6) disposée de manière à pouvoir ouvrir et fermer la partie d'ouverture (2a). La porte (6) présente une partie joint (11) capable d'assurer l'étanchéité de bords périphériques au sommet et au fond et au niveau des deux côtés de cette dernière dans un état fermé, la partie joint (11) comprenant, dans au moins une partie d'une partie latérale ou d'une partie inférieure de cette dernière, un emplacement d'évacuation de joint à partir duquel l'eau en excès qui déborde lorsque le niveau d'eau s'élève à partir d'une surface inférieure du réservoir de lavage (2) peut s'échapper. Le réservoir de lavage (2) comporte : un orifice de trop-plein (14) qui est disposé à l'extérieur de la partie joint (11) de la partie inférieure (6a) de la porte (6), et dans lequel s'écoule l'eau en excès ; et une unité de détection de trop-plein (16) qui est disposée à l'extérieur de la partie joint (11) de la partie inférieure de la porte (6), dans une position inférieure à la hauteur de l'orifice de trop-plein (14) afin de détecter un état de trop-plein. L'invention concerne donc un lave-vaisselle (10) au moyen duquel une nouvelle tentative peut être réalisée si le trop-plein est temporaire.
