Abstract

L'invention concerne un appareil ménager à circulation d'eau (1), en particulier une machine lave-vaisselle, qui, en fonctionnement, comporte des zones mouillées dans lesquelles circule un liquide (FW ; S), en particulier un espace de traitement (2) pour le nettoyage des objets à rincer ou à laver. Au moins une partie (S) circulante du liquide (FW ; S) peut être chauffée et pour cela, un système de commande (16) pour un moteur (13) d'une pompe de circulation (6) est associé à une pompe de circulation (6) équipée d'un chauffage (11), le moteur (13) étant surveillé par un système de sécurité (15). Ledit appareil ménager est réalisé de sorte que le système de sécurité (15) du moteur (13) et l'électronique de commande (16) du moteur (13) ainsi que le système de commande et de sécurité du chauffage (11) soient rassemblés avec la pompe chauffante (6) et forment une unité éprouvée.
