Abstract

L'invention concerne un appareil ménager (1) à circulation d'eau servant en particulier d'appareil de traitement du linge (1) destiné à laver du linge, et comprenant une zone de traitement (3), un capteur de turbidité (14) et une commande (7) mettant en œuvre au moins un programme. Au moins un liquide de rinçage peut être guidé dans la zone de traitement (3) en fonction d'un cycle de rinçage du programme, une turbidité du liquide de rinçage guidé dans la zone de traitement (3) pouvant être détectée par le capteur de turbidité (14) au moins approximativement. En outre, le programme peut être réglé par un utilisateur. Lors d'un réglage du programme au cours duquel une adaptation automatique d'un nombre de cycles de rinçage peut être réglée par l'utilisateur, la commande (7) adapte le nombre de cycles de rinçage pendant le programme en fonction de la turbidité détectée par le capteur de turbidité (14) et, lors d'un réglage du programme au cours duquel un nombre de cycles de rinçage pouvant être choisi par l'utilisateur est réglé par l'utilisateur, la commande (7) met en œuvre le nombre de cycles de rinçage choisi par l'utilisateur dans le programme. L'utilisateur a donc la possibilité, en plus de régler manuellement le nombre de cycles de rinçage, de régler également une adaptation automatique du nombre de cycles de rinçage.
