The watet level does not matter, acording to the german manuals. And temperature restrains HAVE to be in place. So does the pause requirement. Imagine a little kid, pushing that door open mid boilwash cycle.
And sure, you most likely don't want to add something 10 minutes before the wash phase ends.
And I doubt you just forget to add a jumper, hoodie, what ever. And though this door isn't big, I could see me putting jeans, shorts, and even a medium sized hoodie through there.
