> Most of them have a well-hidden faster mode

My shiny new (2025) Bosch washing machine has a big button on the front which switches from the default 3 hour programme (for 40 degree wash) to 1hr 30m. Like, it's not very _well_ hidden :)

Interestingly, the 3 hour programme isn't really a 3 hour programme. If you use it, the timer will generally start at 3 hours and drop to an hour or so after 20 minutes. I have no idea what the heuristic is, and the manual is silent on the matter.
