Even more curious
Between the wash spin and the rinse fill, as in all Unimatics, there is a pause, when everything is off, except the hum of the timer motor; but in your video, there is a distinct pump chug, chug, chugging like that of a conventional Tag or an early 90s DD WP. (Was your Maytag on?) Please take another listen, when you get a sec. Hey, you'll be able to hear Melody crooning again.
Of course Ben, I could be hearing things. ;->
