Our dishwasher has a bright ass white LED when it’s done and clean. As long as you don’t open the door it’s lit up like the Lighthouse of Alexandria. If you’re opening the door, you need to just empty it. Even with that we have a magnet that says “Hella Clean” on one side and “Dirty AF” on the other, makes people actually want to swap it around since it’s not just a basic boring ass dirty/clean sign.
