A washing machine and a method of changing system data therein that can grasp causes such as trouble of the product itself, problems on installation, problems on the regional characteristics, living pattern change of a user, etc., and change/replace a pre-stored program to/by a wash-related program that can solve the problems. The washing machine includes an outer tank, an inner tank, a load section, a microcomputer for controlling drive of the load section and reading an operation state of the load section, a key input section, a display section, an interface section for sending/receiving wash-related data to/from an external device, and a memory for enabling data read/write and storing the program or data received from the external device. If a data-change command is externally or internally produced, the wash-related program is changed through processes of data movement/copy/deletion for each sector in the memory by executing a program for data communication, and thus the convenience in use, washing performance, and operational efficiency can be maximized. Also, the trouble diagnosis and repair performed by the user or service man can be facilitated through the display of the changed program version.
