Claim:
1. A method of operating a dishwasher including a treating chamber for receiving dishes and having both a cool cycle of operation and a hot cycle of operation, which may be implemented in the treating chamber and that may be selected by a user and implemented by a controller, where the cool cycle of operation has a cool liquid temperature insufficient to dissolve fatty soils, and the hot cycle of operation has a hot liquid temperature sufficient to dissolve fatty soils, the method comprising: maintaining liquid temperatures within the treating chamber below the hot liquid temperature for all implemented cycles of operation, regardless of whether the cool or hot cycle of operation is selected; storing in a memory associated with the controller, a running count of the number of cycles of operation implemented within the treating chamber with liquid temperatures below the hot liquid temperature; and when the count satisfies a predetermined threshold count, using a liquid with a hot liquid temperature within the treating chamber when a subsequent cycle of operation is implemented, regardless of whether the subsequent cycle of operation is selected as the cool cycle of operation or the hot cycle of operation.
