Earlier quoted context omitted.
Updates improve wash efficiency, etc. Not just security updates. Maybe a new cleaning powder comes with a new algo. Maybe there's a better dosing for certain levels of water hardness. But the gist is that it updates the whole module. I'm fine with this, Miele are like Bosch in that they look after the hardware they sell for decades rather than considering it deprecated the day it leaves a shop floor.
Every dishwasher I've ever used, your best bet is to put everything on full blast, least efficient settings. Otherwise the dishes get "almost" clean. I always imagine the engineers standing around patting themselves on the back after testing, and marveling how their ideas worked so well most of the dishes got clean. The dishes all need to be totally clean, every time, or it's useless to me.
The big one that drives me nuts on new cars are all the auto start/stop at idle systems. They eat car batteries and starters (increase wear from oil starvation on startup too - consumer car engines are not positively lubricated; pressure has to pump back up every time the engine starts) and there is no way to disable them other than pushing a button every time you start your car (or hacking around with the wiring), but I'm sure they are critical in obtaining higher gas milage requirements so expect them to proliferate. It's crap that happens when you focus on one metric - gas milage - to the exclusion of "the big picture" such as total carbon footprint over the life of the car including the manufacturing and replacement costs/environmental impact of replacing prematurely worn out parts from "energy efficient" design decisions.
