Washing machine is already running, forgot a part?

The other day a washing machine expert gave me a great tip:

It happens more often that the moment you press the start button of the washing machine, you still think of a part of the washing. In order not to confuse the electronics, you let them run and wash the part next time.

And now it's time to try to open the door when the machine is already running. In my case, this is up to a certain temperature and a certain water level, so that nothing can run out or you can scald yourself. And Schwupp is the part in it.
