Most washing machines have a timer that prevents you from opening the hatch just after the washing cycle ends. Instad you must wait for the timer to go off, usually a minute or two, before you can open the hatch.
Why? Would letting the user open the hatch immediately after washing ends pose any safety or other issues?
Mine beeps when the door unlocks, but I’ve seen many that beep before the final check. Either to satisfy some “1 hour wash cycle” target or perhaps they expect people to walk to the machine when it beeps and the check isn’t that long so it’s probably going to be unlocked when you get there?
I’m looking for this beep-and-unlock feature next time I buy a washing machine…
