I recently bought a new washing machine. It has a mode with an odd name that turns out to be tied to a cleaning product from another company. The manual doesn’t have any information on what the mode does or why it exists. The manual is a generic manual for like 5 or 10 models, and seems to only include the functions common to them all. Any function on a higher-end model that’s not included on the lower-end model is just not documented. I guess if you want to use those, you’re on your own.

But of course, there’s a phone app you can download and give the company a bunch of personal information to connect your washer to your home network so you can get notification when it’s done with its cycle.
