Does not stop running

I received this from GWOL... and it corrected my problem.
Typically this means that there has been a water leak of some sort and there is water in the lower base pan. This is the large white plastic base that the dishwasher sits on.

If you remove the toe kick and look back past the fill valve on the extreme left side of the dishwasher about 6 to 8 inches from the front you will see a red stick that goes straight up and down. This is a mechanical linkage that activates the drain feature. Be careful as there are live connections here.

This stick rests on a round piece of Styrofoam that acts as a float. If there is water present it will cause the stick to lift and the dishwasher will go into drain. The source of the leak will have to be isolated and corrected. Most likely it is the fill float assembly as referenced at the end of this post.

If the stick is not in the upright position then there is possibly an issue with the switch mechanism itself.

You will have to pull the dishwasher out from beneath the cabinet and remove the panel covering the left hand side. If it is a full panel then there are a couple of screws holding it on from the front through side trim as viewed when the door is open if it is a half panel then it can be removed by removing the large torx screw on the lower right as seen when facing the panel.

If there is a problem with the switch then the entire mechanism should be replaced.

Try the following link to a picture for reference. It is upside down as compared to the installed one:

Hi,
I had a problem with a clog in our garbage disposal drain pipe. The pipe was cleared up but subsequently the dishwasher is not functioning. When the door is opened and the on/off button is pushed the motor automatically starts running without a cycle being selected. Also, there doesn't seem to be any water getting into the washer. It is a siemens SL84A302UC-01 It was working perfectly the day before. Can you help me?
Thanks
