We've been having some confusion lately over whether the dishwasher has been run yet or not. The ancient one we had before had a light that came on when it had completed its cycle, and the light stayed on until you physically turned it off after you had emptied it.
The new dishwasher has a light that comes on, but the light automatically turns off the first time the door opens. So if someone just reaches in for a clean fork, but doesn't empty the dishwasher, the next person that comes along may think the dishes haven't been washed yet and add a used plate to the rack. (We do a pretty thorough rinse job before putting them in the dishwasher, so they usually look clean even if they haven't been washed yet.)
Hello clipart and card-making supplies!
I happily found everything I needed in my stash to solve the issue. Printed the graphic, layered with pretty paper, laminated to keep it tidy, added tiny but strong magnets.
Now all I have to do is train whoever starts the wash cycle to turn the sign to 'clean', and whoever puts clean dishes away to turn the sign to 'dirty'...myself included.
