Now dishwashers require WiFi to work. This should be against the law. It's certainly against common sense. My wife bought a Sonos boombox a couple of years ago, and the first time we turned it on I discovered that you had to download an app to control the volume. It went back in the box and back to the store. A dishwasher, once you have installed it, has a higher time cost to box it back up and return it.
The point of the story is that if you are buying large or small appliances, read the fine print before you buy. And the dreaded 10 mm socket also makes an appearance in this horror story.
