Water-conducting domestic appliance and method for operating a water-conducting domestic appliance

Abstract

A water-conducting domestic appliance includes a dispensing apparatus configured to dispense a cleaning agent into a dishwasher cavity of the water-conducting domestic appliance, and a controller configured to carry out a number of wash programs for washing items to be washed and to carry out a cleaning program for cleaning the water-conducting domestic appliance. The cleaning program includes a first cleaning phase with a first cleaning agent at a first temperature and a second cleaning phase with a second cleaning agent at a second temperature. The controller is configured to actuate the dispensing apparatus such as to dispense the second cleaning agent into the dishwasher cavity during the second cleaning phase.

         15 . The domestic appliance of  claim 14 , constructed in the form of a dishwasher. 
     
     
         16 . The domestic appliance of  claim 14 , wherein the first temperature is higher than the second temperature. 
     
     
         17 . The domestic appliance of  claim 14 , wherein the first temperature is higher than 60° C. 
     
     
         18 . The domestic appliance of  claim 14 , wherein the first temperature is in a range of 65° C. to 80° C. 
     
     
         19 . The domestic appliance of  claim 14 , wherein the second temperature is in a range of 45° C. to 55° C. 
     
     
         20 . The domestic appliance of  claim 14 , wherein at least one of the first cleaning phase and the first cleaning agent is configured to dissolve limescale, fat and/or microorganisms. 
     
     
         21 . The domestic appliance of  claim 14 , wherein at least one of the second cleaning phase and the second cleaning agent is configured to dissolve carbohydrate, protein and/or cellulose. 
     
     
         22 . The domestic appliance of  claim 14 , wherein the cleaning program includes a pre-rinse phase prior to the first cleaning phase. 
     
     
         23 . The domestic appliance of  claim 14 , wherein the cleaning program includes an intermediate wash phase between the first cleaning phase and the second cleaning phase. 
     
     
         24 . The domestic appliance of  claim 14 , wherein the cleaning program includes an intermediate wash phase after the second cleaning phase. 
     
     
         25 . The domestic appliance of  claim 14 , wherein the cleaning program includes a rinse-aid phase after the second cleaning phase. 
     
     
         26 . The domestic appliance of  claim 14 , wherein the cleaning program includes a final drying phase. 
     
     
         27 . A method for operating a water-conducting domestic appliance, comprising:
 configuring a cleaning program for cleaning the water-conducting domestic appliance such that the cleaning program includes a first cleaning phase with a first cleaning agent at a first temperature and a second cleaning phase with a second cleaning agent at a second temperature; and   carrying out by a controller the cleaning program such that the dispensing apparatus is actuated to dispense the second cleaning agent into a dishwasher cavity of the water-conducting domestic appliance during the second cleaning phase.   
     
     
         28 . The method of  claim 27  for operating a dishwasher. 
     
     
         29 . A computer program product embodied in a non-transitory computer readable medium, wherein the computer program product, when loaded into a controller of a water-conducting domestic appliance and executed by the controller, causes the controller to:
 carry out a cleaning program having a first cleaning phase with a first cleaning agent at a first temperature and a second cleaning phase with a second cleaning agent at a second temperature; and   actuate a dispensing apparatus of the water-conducting domestic appliance to dispense the second cleaning agent into a dishwasher cavity of the water-conducting domestic appliance during the second cleaning phase.
