I was just here to see if anyone has a simple (not battery) idea of how to detect if the dishwasher is open/closed. But I'm happy to read all the other comments.
My recommendation is to read the manual, our dishwasher has this function. But I needed to enable it, and it doesn't by default work in all modes. Maybe it's good to check?
Is the end goal to know if your dishwasher has finished? If so, a smart plug with power monitoring could tell you that.
The end goal is trying to automate when the dishwasher is emptied by a person. I've been tracking a lot of power things already to get there status. So in the kitchen there is a led kickboard that shows the color of the appliances
Nice. you can look out for a project with esp home and a contact sensor. Here is an exemple

maybe just a window/door sensor that uses a magnet to detect closure?
Would work but is a challange with an intergrated dishwasher. And I've been trying to avoid batteries (unsuccessful but trying)
