Turn the dishwasher on to any function, however, it's important that first it pumps the water OUT of the dishwasher. When you see that it pumped the water out, then turn it off.
I too have a DW80K7050UG that is beyond awful smelling. I've had multiple Samsung products and this experience will be ending that for myself as well as as many friends and family who will listen to my story if i am unable to get an accomodation. The "solutions" they tell you to try over and over again are a joke. None of that works to escape the rancid smell that fills the room. I literally leave the dirty dishes in the sink when guests are over and wait to load it until they leave because yes in the sink smells better that this awful unit. I have held multiple phone and chat sessions, having to explain my story over and over AND OVER again, and taken days off work to meet with technicians that tell me quite literally this is a complaint they get daily with Samsung dishwashers and there is nothing they can recommend futher. After speaking with a friend regarding my issue she said she was advised at Lowe's not to purchase a Samsung dishwasher because of this exact issue. That is shameful that Samsung would continue selling these units and not stand behind this product if a known issue is at hand.
I found the the issue. Open the dishwasher door and reach your finger under the bottom gasket that seals the door shut. There you will find a build up of rotting food. Clean it once a month with a Clorox wipe and it will be like a new dishwasher.
sorry, I've been hunting and pecking for a while now- while the "hanging loop" theory makes sense, I too have a new dischwasher that smells terribly, but we do NOT have a dispoosal in the sink.
Anybody out there have the same problem? Smelly dishwasher but no dgarbage disposal back-drain to blame? BTW, it semlls after a few hours with the clean dishes still in it, depiste the fact ot opens when its done. its hooked up useing the same connections my old Sears dishwasher used. and another thing- why does it take 2-3 hours to clean? nad why is it always dripping wet in there? The old one was dry after the cycle.
Responding to this post because the drain hose was installed properly (ran high through cabinet wall and then back down to kitchen drain) but still had smelly dishwasher.
Moved into a home with existing Samsung dishwasher (DMT400). Noticed bad smells after dry cycle. Took apart the filter unit at bottom of tub and found grayish beige chunky slime over many of the parts (this involved removing the lower spray arm, the filter cover, and a spinning disk). Cleaned it all and reassembled. The smell was better but still noticeable from the door. Took off a metal cover to the vent near the top inside of the door and found more of the same 'growth or residue' on the inside of the metal cover and plastic grate (it twists to release--the two screws just below are for removing the vent housing inside the door and don't need to be removed). I pushed down the black diaphragm to thoroughly clean the entire area.
Hopefully this resolves the smell once and for all. Hard to know if previous owners had maintained and used the dishwasher appropriately to prevent this build up in the first place. However, had also seen posts about a black grime along the inner rubber seal and I have also seen this and cleaned it and seen it reappear within a couple months. Although disgusting, not sure it was the source of our smell.
Maybe the lawyer that that has taken on the ice maker class action would be interested in this one too?
Only satisfaction comes from chasing away potential Samsung customers in Lowe’s/Home Depot (5 last Thursday-one was looking at a 4000 refrigerator).
I am there almost daily due to my job.
