Patent ID: 8734590

Claim:
A dishwasher, comprising: a control device in which at least one wash program is stored to control a wash cycle for cleaning items to be washed; a washing chamber in which the items to be washed are located; a water inlet device having a hot-water valve controlled by the control device and a cold-water valve controlled by the control device, the hot-water valve to take in hot water from an external hot-water supply and the cold-water valve to take in cold water from an external cold-water supply; at least one temperature sensor arranged downstream of the water inlet device; and a spraying device for spraying the items to be washed; wherein the control device is programmed to control the hot-water valve of the water inlet device, during a first phase of an intake phase, to take in only hot water into the washing chamber without spraying the items to be washed with the hot water and to compare a temperature of the hot water measured by the at least one temperature sensor to a predetermined temperature of washing liquor for the wash step before spraying the items to be washed, wherein, if the temperature of the hot water measured by the at least one temperature sensor in the first phase of the intake phase is greater than the predetermined temperature of the washing liquor for the wash step, then the control device is programmed to control the hot-water valve and the cold-water valve of the water inlet device, during a second phase of the intake phase which is subsequent to the first phase of the intake phase, to take in both hot water and cold water into the washing chamber without spraying the items to be washed with the water, and wherein, if the temperature of the hot water measured by the at least one temperature sensor in the first phase of the intake phase is one of less than and equal to the predetermined temperature of the washing liquor for the wash step, then the control device is programmed to control the hot-water valve of the water inlet device, during the second phase of the intake phase, to take in only the hot water into the washing chamber, and wherein the control device is programmed to control the spraying device, during a spraying phase which is subsequent to the intake phase, to spray the items to be washed with the washing liquor containing the water that has been taken into the washing chamber via the water inlet device if the temperature of the washing liquor is equal to the predetermined temperature of the washing liquor for the wash step.
