Whirlpool Dishwasher strage problem

I have a whirlpool dishwasher that stopped working one day. I called the local repair guys and they came out, said it needed a new front panel and that the part would take 3 months to get. I convinced them to order the circuit board and I replaced it. It fixed the problem and the washer worked again. Then about 4 weeks later it stopped working so I ordered a replacement circuit board and replaced it myself and it worked again. Then a few weeks later the same thing happened. This time I purchased the front panel and the circuit board, replaced everything and all was fine for about a month. Now it’s not working again. Something is obviously frying the circuit board. Any ideas? It’s not the front panel because it’s been replaced and I never thought it was bad in the first place… Model [FONT=Arial]KUDM01TJBS0[/FONT]

Anybody have any ideas here? I don’t want to buy a new dishwasher if this is a simple fix, and don’t want to throw money at something that is dead??? Help???
