Keeps running - Whirlpool 24 in. DU1100XTP Built-in Dishwasher

Hello, The first thing that you would have to be able to tell is which cycle of the dishwasher is it that keeps running. Most of the time when this happens the unit keeps running on the drain cycle in which the unit either detects a leak in the system that the pump is trying to clear the water from the unit leaking water out of the machine. Another reason would be if you had a clogged drain line, In order to check for an issue with a clogged drain line you would first go under you sink. You would then disconnect the drain line to the exit water port either on your disposal,or sink piping. You would then visually inspect the inside of the exit port where the drain line connects to. Alot of times I find that this area does get gunked up with debris from the disposal. After assuring that this area was functioning properly you would then have to de-install the dishwasher from under your counter in order to check the rest of the drain line as well as the pump itself. You can check the rest of the drain line by disconnecting the line from the pump cleaning this connection end point and blowing air through the line which would tell you if there were any clogs in the line at all. If there were no clogs in the drain line you would next look at the pump itself and have to assure that the impellar inside the pump is spining. If it were not then you would replace the drain pump. I will await your reply as to which cycle you think that the unit is constantly running in before further diagnosing your issue at hand. I await your reply
Thank you
