Abstract

L'invention concerne un appareil ménager à circulation d'eau (1), qui sert en particulier d'appareil de traitement de linge pour le lavage et/ou le séchage de linge, comportant un réservoir (15) servant à recevoir au moins un agent de traitement liquide, une pompe de dosage (19) entraînée par un moteur électrique (18), et une commande (23) servant à commander le moteur électrique (18) de la pompe de dosage (19). En mode de fonctionnement normal, la commande (23) commande le moteur électrique (18) de la pompe de dosage (19) de sorte que la pompe de dosage (19) refoule l'agent de traitement liquide du réservoir (15) dans la zone de traitement (9). En mode de fonctionnement nettoyage, la commande (23) commande le moteur électrique (18) de la pompe de dosage (19) au moins par moments de sorte que le moteur électrique (18) produit un couple de rotation plus élevé et/ou variable pour entraîner la pompe de dosage (19). Ainsi, en mode de fonctionnement nettoyage, la commande (23) peut commander le moteur électrique (18) avec une tension plus élevée et/ou pulsée, ce qui permet de nettoyer la pompe de dosage (19) et d'autres éléments d'un dispositif de dosage (16) de l'appareil ménager (1), et donc de faciliter l'utilisation et le nettoyage du dispositif de dosage (16) pour un utilisateur.
