Why does the washer door not open after a cycle?

The door will not open if water remains in the drum — drain the drum first and then open the door manually. The door lock light must be off before the door will open, and it may take a few moments for the door lock mechanism to disengage after pressing Start/Pause. If the power cord was unplugged during operation, plug it back in, turn on the power, and press and hold Start/Pause to stop the operation. (Page 18)
