That is interesting. I bought my unit in NH, live in Maine, and have the ice maker. There is a valve under the kitchen sink to shut the water off to the ice maker and then you open up the drain you mentioned and drain the water from the ice maker. You do this if you are cold weather camping. There is also a flex line connection that is under the kitchen slide. I broke loose that fitting as well to ensure all water had drained. That said I will see if all of that was successful when I open it back up this spring. I think I would tell your dealer that you want the ice maker, because it is not an option on the 3711, it is supposed to be in the Samsung refrigerator. It is my opinion that you paid for it and it should be there. I would suggest contacting Keystone to confirm that. All that aside, enjoy your unit and travel safe.
