I have an LG dishwasher, with a replacement hose that has a black connection that goes to something, somewhere however mine is 2006 manufacturer and the new hose that I ordered does not tell us where to hook up the third dishwasher connection. It appears that the connection goes on the later models to a tube where it is connected, however mine does not have that connection. My serial number is 612KWVC01278 if that helps. I would really like a tech to tell me where to put this third connection or do i just plug it with something.
