I have a Maytag washing machine & dryer from 1955 that still run and the only thing either ever needs is a new belt every 15 years or so.

I've seen the inside of modern washing machines and the difference between the two is stark.

Both machines are actually extremely simple, but the Maytag is incredibly overengineered. Every last component is quality.

Modern machines do everything in the PCB but every component had maximum cost squeezed out of it.
