SOURCE: I have the same SE error message on my Samsung dishwasher.

An "SE error" indicates a drain problem. The first time I saw this error on my DMR78AHS, I experimented with different scenarios and cycles involving my washer for about a week... to no avail. Finally I pulled it out and found that the contractor who installed it had accidentally crushed the attached drain hose against a 2x4 inside the counter when they pushed it back under the counter. I had to cut off the crushed part of the hose and reconnect it the drain line with some hose clamps (this is not ideal). If it was recently installed, you could explore this option or you could simply try to snake the line, starting from where the drain hose attaches to your sink's drain. You may also want to get a professional to help such as a plumber or a dishwasher specialist.

I have the se problem...only one year old. Since then change Samsung drain hose (theres a one way check valve inside) and replaced with a universal one from home depot (no check valve). At the same time bought correct hose being shipped from china so took awhile to get here to America. To simplify my point in telling you, depot hose flows better, less resistance, and bigger openning; like 1/2 to 3/4 difference. Guess what? No drain issue and se is back before I even install correct hose. Well warranty is up next month so now service tech can make the call as my warranty runs out....sure he will fix it for a month or two but problem will come back and stuck buying another model. Samsung has since stop making this stainless steel model for a reason. What a expensive piece of junk and in the interest of someone like myself who has all Samsung ss kitchen should give me another knowing theres a known issue. So I wont be happy with patch as only so much that can be done with **** product. This is what I think is real issue. The electronics of this machine cant handle the one way check valve limited drain flow so although corrected their issue with bigger hose its already too late unless was done from beginning. From reading online complaits clothing or dish washer same issue error code SE (not real issue) and wont work. If I seem a little angry cause previously owned worked better and lasted 8 years without any ANY problems.
