There's no user error, just bad design.

This is an aphorism, not a truth. But it’s true that dish washing machines are often badly designed, especially when there are multiple opaque options that can be turned on and off. Consider the example presented in this very video, where the “Eco” cycle uses more water and more energy than the normal cycle and where the “High Temp” option adds more wash cycles as well as heating the water for longer. No amount of design can save the user from misunderstanding what these options do. The only way for the user to use the machine correctly is, at a minimum, to read and learn from the service guide (or other documentation) which gives explicit details about what each wash cycle is supposed to do. If you watch the supplementary video you’ll find that even that was incomplete and had errors; full understanding required hacking the dishwasher to reveal which parts of the machine were active (inlet, heater, pump, etc) and for how long.

Therefore I stand by my assertion that if you refuse to learn the details of what your dishwasher actually does then you will probably be using it badly.
