Abstract:
1. A method for controlling a household appliance, particularly a washer or a dishwasher, having an I/O control for programs and a machine unit comprising a central control that controls assigned functional units according to the selected program, wherein an interface is configured between the I/O control and the machine unit for the transmission of program-specific commands, wherein in the I/O control the program selection criteria entered by an operator, or information received by a remote transmission, are converted into assigned program-specific commands, wherein the program commands are received by the machine unit and converted into the functional commands for the functional units of the machine unit, wherein the I/O control is provided with selection means for the program data to be selected, and display means for the display of the selected program data, wherein the program data that was pre-defined by the selection means or that are received from the remote transmission are converted into the program-specific commands via the input converter, wherein the program-specific commands are transmitted to the machine unit and converted into the functional commands for the functional units, wherein the interface between the I/O control and the machine unit comprises a coder/decoder in the I/O control and a decoder/coder in the machine unit as well as a two-way transmission link between the coder/decoder and the decoder/coder, wherein the program-specific commands in the I/O control are configured depending on the chosen selection means via the input converter and the coder of the coder/decoder and are routed to the transmission link, wherein the program-specific commands received by the machine unit are routed to a machine-specific converter via the decoder of decoder/coder, wherein the central control receives input signals from the machine-specific converter that are specific to the central control, wherein the functional units and/or the central control route check-back signals to the machine-specific converter which are converted in the machine unit via the coder of the decoder/coder and routed back to the UO control via the transmission link, and wherein the incoming check-back signals from the decoder of the coder/decoder are received in the I/O control, and converted by the input converter and displayed via the display means.
