I have A KitchenAid dishwasher I don't know exactly how to explain it but the four hour delay button on the front panel stays on but nothing else works. You can push all the buttons nothing else works. I hit clear and the light goes off on the four hour button but I can still get any other button and nothing works. A few days ago there were a few other lights on and they were just blinking but they're not blinking now what could be wrong?

More than likely you have something sticking, like the float level switch or something like that. Make sure to check your filter and take the spray arms off and see if they have trash in them, then check the pump clean-out. Here are some manuals: https://dl.dropboxusercontent.com/u/8010163/KitchenAid%20KD-01%20Stainless%20Steel%20Dishwasher.pdf

Another problem that is very common with that dishwasher is that the control panel where the buttons are located gets dirty from moisture getting into it. To repair it you have to remove the panel and peel off the rubber front and clean both surfaces with dishwashing soap and water with an old soft toothbrush. Under each button you will find a carbon disk that makes contact with the contacts printed on the circuit board. Make sure you are very careful cleaning these and if one is loose make sure to glue it back on. Then wash off with water and then alcohol (95% isopropyl) and let dry in sun or a warm, dry place. Check for corroded or loose connections which also may be causing your problem. You can find these all over the machine, but more than likely around sensors and safeties.
