11. The water-conducting household appliance of claim 10 , wherein the special cleaning program is identical to the high-temperature wash program.
12. The water-conducting household appliance of claim 4 , wherein at least one of:
the counter unit is configured to increase a counter status for each wash cycle performed by a count value of “1”; and
the limit counter status lies within a range of 1 to 5.
13. The water-conducting household appliance of claim 12 , wherein the limit counter status is at 3.
14. The water-conducting household appliance of claim 6 , wherein, for weighting the at least one recorded influencing variable, the control device assigns a respectively different count value to the at least one recorded influencing variable.
15. The water-conducting household appliance of claim 1 , wherein, in the special cleaning program, the washing liquid is applied at least to areas of the water-conducting household appliance prone to soiling, and wherein the temperature of the washing liquid is sufficiently high to remove grease deposits.
16. The water-conducting household appliance of claim 15 , wherein the temperature of the washing liquid lies within a range of 65 to 75° C.
17. The water-conducting household appliance of claim 1 , wherein the water-conducting household appliance is a dishwasher and a heating phase subprogram step of the special cleaning program is configured to heat the washing liquid to a cleaning temperature and disable an upper spray plane so that an entire hydraulic circuit operates via a lower spray plane.
18. The water-conducting household appliance of claim 1 , wherein the special cleaning program is configured to operate a circulation pump connected to a hydraulic circuit at higher speed.
19. The water-conducting household appliance of claim 10 , wherein the control device is configured to carry out the special cleaning program when the start signal is generated regardless of whether one of the at least one wash program stored in the control device is selected by a user.
20. The water-conducting household appliance of claim 1 , wherein the start signal is generated based on a condition of the washing container.
21. The water-conducting household appliance of claim 1 , wherein the washing container is configured to hold items to be washed and the user-selected wash program is adapted to clean the items to be washed.
22. The water-conducting household appliance of claim 1 , wherein the washing liquid source is configured to supply the same type of washing liquid to the washing container during the performance of the user-selected wash program and the special cleaning program.
23. A water-conducting household appliance comprising:
a washing container configured to hold items to be washed;
a control device configured to carry out a wash cycle according to one of a special cleaning program adapted to clean the washing container and a user-selected wash program adapted to clean the items to be washed; and
a washing liquid source configured to supply the washing container with a washing liquid during performance of the wash cycle,
wherein the control device is configured to carry out the wash cycle according to the special cleaning program instead of the user-selected wash program in response to a start signal generated without user input.
24. The water-conducting household appliance of claim 23 , wherein the special cleaning program is configured to supply the washing liquid at a higher temperature than the user-selected wash program.
25. The water-conducting household appliance of claim 24 , wherein the special cleaning program is configured to supply the washing liquid at a greater flow rate than the user-selected wash program.
26. The water-conducting household appliance of claim 25 further comprising a hydraulic circuit with an upper spray plane and a lower spray plane, wherein the user-selected wash program is configured to direct the washing liquid through the upper spray plane and the lower spray plane, and wherein the special cleaning program is configured to disable the upper spray plane.
27. The water-conducting household appliance of claim 23 , wherein at least one of a low-temperature wash program, a medium-temperature wash program and a high-temperature wash program is stored in the control device, and wherein the user-selected wash program corresponds to one of the wash programs stored in the control device.
28. The water-conducting household appliance of claim 27 further comprising a signal generating device connected to the control device, the signal generating device being configured to generate the start signal.
29. The water-conducting household appliance of claim 28 , wherein the signal generating device has a counter unit configured to generate the start signal upon reaching a limit counter status.
30. The water-conducting household appliance of claim 29 , wherein the counter unit is configured to increment as a function of at least one recorded influencing variable that influences the level of soiling of the household appliance.
