Bendix!
My Grandmother had a simular bendix, but hers had a complete round window door and the dispenser had a smaller square door. Also a grey dial on each side with the timer on right that had a seperate soak cycle and up to a 12 minute wash. The dial on the left was for the water level. (at least in those days you can get water in these machines) In the center was a 2 button selection for hot or warm water. I don't know if it had a heater. I do remember when she would do a hot wash she would switch the machine to warm after it filled but I don't remember why she did that. Me and my sister always had so much fun watching the bendix run. I wish they made machines like that today.
