Mine opens with the long press of a button.
But my beep gives me a different problem, I never hear it. Imagine a shy introvert whispering, "Excuse me, if it isn't any trouble, would you please kindly move your laundry?" From across the apartment behind several closed doors.
The end result is me nerotically checking it, and sometimes it just refused to end. Like the timer says some amount of time and nothing is happening. If I open it, the display sheepishly flashes CL, which I assume means clean and not clear.
