A water softner will not make the dishes any cleaner, it just makes it so they don't have water spots on them.
If the dishes are dirty, it is most likely that the nozzles (holes) in arms may be plugged.
Also check to make sure you are getting plenty of water to dishwasher. Make sure all water valves are full turned open.

If the control panel does not work all the time, it is very likely you have either a shorted wire, or a fualty main board which is very common in newer machines.

I was so impressed with the advice on this website, I thought I would take a stab at this. The difference is, I will include all the steps, so if I go into a little too much detail for you, I'm sorry, but I felt a few things got left out that needed to be said.

Tools Needed: screwdriver with t-15, and t-20 torx bits (available at any hardware store), and a pair of pliers. Also I used a headlamp so I did'nt have to hold a flashlight with my teeth.

step#1- Clear a spot on your counter or kitchen table and remove both the lower and upper racks from your dishwasher. The lower rack just lifts out, the upper you will find two light blue plastic caps that once removed will allow you to slide the rack off of the metal slides. Next, the long L shaped spray bar that goes up the back and across the top needs to be un-clipped and removed, 2 clips at top and 2 clips at the back. It might take a little wiggling but that spray bar slides into the top cover, once unclipped push back at the bottom and tilt the upper part toward you, it should come out fairly easily and give you wide open access to the cover. Next you want to remove the plastic nut that holds the spinner in place, using your pliers turn it counter clockwise, it should loosen fairly easily, and remove nut and spinner. Next with either a T-20 or T-25 torx bit, remove the 3 screws that hold the outer cover in place, notice the direction of the tube that plugs into the spray bar, make sure it goes back in the same way. Now remove the T-15 screw that holds the black grinder cover in place and remove screw and cover. Now remove the 6 screws that hold the inner cover in place and remove the cover. You can now see what all the fuss was about, mine included a piece of pistachio shell, a bay leaf, and a cherry pit. Once it's all cleaned out, just reverse these steps and be ready! You have just earned your place as your homes resident handyman or woman!
