The only thing in my 6 year old washing machine that has been broken was the circuit board. Part mainly needed to cycle trough the menu because they put that instead of analog buttons. Meanwhile, I know people with certain German brand machines that are 30 years old and running perfectly for the entire 30 years, and if something would break it would 9 out of 10 be super obvious and mechanically easy to fix.

Sometimes smarter is definitely not better.
