Problems solved by technology

However, the traditional washing machine cannot understand its operating status, use failure records, etc., so it cannot correctly analyze the above reasons.
[0015] The washing machine designed with the traditional technology described above cannot save information about the product’s operating status, use history, and failure history, so it will not be possible to determine the cause of the above failure during repairs.
Therefore, only using the method of replacing parts, that is, using the method of replacing hardware to repair the product, the same failure will still occur
