please excuse my mess! but I just couldn't believe my eyes when I flipped through YouTube videos that all said you had to take apart all the connections to the dishwasher in order to replace the door gasket, at least on this type of dishwasher. hope this helps you if you are in the same boat.
and also, please excuse my face lol, I'm sick and I tried to smile so I wouldn't look scary, but it's just so forced it looks funny.
