Product review (3 stars): Door problem
I purchased this dishwasher based on my experience with Samsung.  All my other appliances are Samsung and I have had no problems.  The door latch issue started almost from the beginning - either the door would not close at all or it would come open during the cycle.  After completing the online registration with the Samsung support site, you need to go through their troubleshooting.  The last step did it for me.  Give the middle shelf a tug.  Something snapped back into place and the door problem has disappeared.

Update on 1/6/15:  We finally had service come out and do warranty work on this.  They replaced the rails that hold the middle rack.  This is a common problem and my repair guy said he had fixed at least 6 of them.  Got rid of the LE code too by fixing the rails.  We have not had any problems since this was done but you have to be sure that the rack is locked into place when you close it - do a slight lift as you push it in which locks it in place so it can't open the door during the run.
