My old washing machine had nobs (dials) you turn. You put the clothes and soap in, close the door and press the button. My preference of type of wash and water temperature were all "saved" by the nob position.
My current washing machine, nob is type of wash, capacitive touch buttons for everything else. Keeping the nob "on" keeps the digital display on and consuming power. And the wash options like temperature, extra rinse etc are all controlled digitally with no memory. Want 60 degrees water? Press the water temperature button 8 times, each with a delay of about 3/4 of a second for it to register before a press works again. It's utterly terrible.
