Tap Play/Pause to pause. Opening the lid pauses it for you.
Lifting the lid mid-cycle pauses the machine safely. The cycle resumes when the lid is closed. On pause, only the time flashes. Every icon holds its state.
To reset, pause the machine, then press and hold Power until the Power button greys out. The machine drains. The panel stays unusable until the drain finishes, then the machine switches itself off. Power it back on to use it again.
