I have the solution! Had error 4 and had the repair guy come....he said its caused by too many suds...if you are using tablets that have rinse aid as well as rinse aid, it causes to many bubbles, these get sucked down the two little outlets (located at the bottom of the dishwasher door, easy to see if you open the door completly) and make the water level in the base seem higher than it actually is which triggers the over flow button. Now to fix it is SUPER hard....NOT! Just pull out your dishwasher, and tip it back slightly. The water stuck in the base will trickle out...not much but will take 5-10 mins. Then turn it on, run on a rinse cycle to be sure its all gone! Easy Peesy. I called whirpool about this, and why they could not tell me how to fix it is beyond me......they told me to press and hold the start button...i dont think even they know how to fix it! So...I got to do this under warranty, now hopefully you get to fix it for free and we all win. Yay!

I just had the same thing, same model. After cleaning the filter out, the problem remained. I then read on another forum that it helps if you tilt the machine backwards for a few minutes (which involved pulling it out of the cavity in the kitchen). Did this and it now seems to be working. Hope this helps you.
