Dishwasher having two water connections and control method

A method for controlling at least one wash cycle of a dishwasher, comprising:

• activating one of first and second operating modes based upon a determination of which of the first operating mode and the second operating mode is more efficient,
• wherein in the first operating mode a wash program is activated by a program control device to draw hot water from an external hot water supply to execute at least one partial wash cycle of a wash cycle;
• wherein in the second operating mode another wash program is activated by the program control device to draw exclusively cold water from an external cold water supply to execute at least another partial wash cycle of the wash cycle, and
• wherein the wash program and the other wash program are each complete wash programs for cleaning dishes;
• and
• switching from the first operating mode to the second operating mode when water temperature from the external hot water supply falls below a predetermined limit.

A dishwasher, comprising

• a hot water inlet device for intake of hot water from an external hot water supply;
• a cold water inlet device for intake of cold water from an external cold water supply;
• and
• a program control device programmed to control a wash cycle of a selected dishwashing program for cleaning wash items, said program control device being programmed to operate in first and second operating modes,
• wherein the first operating mode includes activation of one wash program which, in at least one first partial wash cycle of a first wash cycle, draws hot water from the external hot water supply,
• wherein the second operating mode includes activation of another wash program which, in at least one second partial wash cycle of a second wash cycle, exclusively draws cold water from the external cold water supply,
• wherein the program control device is programmed to select the first operating mode or the second operating mode based upon a determination of which of the first operating mode and the second operating mode is more efficient,
• wherein the one wash program and the other wash program are each complete wash programs for cleaning dishes, and
• wherein the program control device switches from the first operating mode to the second operating mode when water temperature from the external hot water supply falls below a predetermined limit.

A dishwasher, comprising

• a cold water inlet device for intake of cold water from an external cold water supply;
• and
• a program control device programmed to control a wash cycle of a selected dishwashing program for cleaning wash items, said program control device being programmed to operate in first and second operating modes,
• wherein the first operating mode includes activation of one wash program which draws hot water from the external hot water supply and cold water from the cold water supply in different wash cycles,
• wherein the second operating mode includes activation of another wash program which exclusively draws cold water from the external cold water supply for all wash cycles,
• wherein the program control device is programmed to select the first operating mode or the second operating mode based upon a determination of which of the first operating mode and the second operating mode is at least one of more economically efficient and more cleaning efficient, and
• wherein the one wash program and the other wash program are each complete wash programs for cleaning dishes.

• wherein the program control device is programmed to select the first operating mode or the second operating mode based upon a determination of which of the first operating mode and the second operating mode is more efficient,
• wherein the one wash program and the other wash program are each complete wash programs for cleaning dishes, and
• wherein the determination of which of the first operating mode an the second operating mode is more efficient is based upon whether it is more economical to draw heated water from the external hot water supply or whether it is more economical toheat water in the dishwasher.
