Invest 5 dollars in a pack of shims. Of course the true fix is to get that bottom replaced, but as that can be pricy I would use the shims or a block of wood as long as it is sturdy and stable when done you shouldn't have any issues

My LG dishwasher is missing the front adjustable feet and the bottom tray/frame is broken on one side where the foot would be installed so installing new feet doesn't do any good. I was wondering what the best option would be for properly installing the dishwasher so it would be stable short of replacing the entire bottom plastic piece and installing new feet. I was considering cutting a piece of 2x2 down to size to raise the front end up to meet the cabinet but didn't want to go through the trouble before knowing if it was a good option. Any suggestions, advice, or tips would be greatly appreciated. Thanks, Beau.
