Fortunately, I had an ancient Scrabble game that likely was missing pieces, so I didn't feel bad about using some of the tiles for my project. I wouldn't dare use our current Scrabble game.
For the project I used a piece of black craft felt, the scrabble tiles to spell CLEAN and DIRTY, some crafters glue, and a flat magnet.
I cut a piece of felt 1 1/2 x 3 1/2 inches for the backing for the letter tiles. I applied glue to each tile back and to the sides that touched the next tile, placing each one carefully in line on the felt backing.
Glue both rows of tiles in line, being sure to place the words so that they will read correctly when the magnet is flipped over.
Give the glue some drying time, then cut the magnet to size if needed and glue to the back. I gave mine time to dry overnight before using.
The next morning I was ready to place my new magnet on the dishwasher and have the "Clean or Dirty?" question forever after answered. Well, the best laid plans sometimes do not work out as planned, I suppose. I unloaded the clean dishes, and slapped my new magnet to the front to show that the dishwasher was ready for "Dirty" dishes, but the magnet just slid to the floor with a dull thud. One thing my brain had failed to process in my planning, my dishwasher is made of stainless steel - magnets won't stick.
I hope this mission will be more helpful to someone else than it was to me! My daughter Angela says her dishwasher is a metal that will hold a magnet, and that she would love to use my Scrabble magnet, so maybe it will be useful to her at least.
For now I am still trying to answer the question, "Are the dishes clean or dirty?"
