Check the brackets that hold the top rack for any broken plastic brackets. My dishwasher was making the same noise and after noticing the broken plastic pieces I pulled out the dishwasher put it on its side removed a white panel on the bottom that is attached with two screws, removed the drain line and inside there were two plastic tabs from the broken bracket. Once those were removed the grinding noise stopped. The bracket holding the drain hose can be removed with a pair of pliers.
I wish I knew that earlier.. I've been having that issue intermittently and now my dishwasher hasn't worked in two months.. I'm getting an SE error about a minute after starting the cycle, there is no noises when I turn it on and the cycle stops once I get the SE error. I'm going to attempt what you suggested above right now and let you know if it resolves my issue
Wow, your awesome Fultondsan... That fixed it..
Genius......same issue for my DMT800RHS
Wow I knew it had to be in the pump but I didn't know it was the impeller that pumps the water out...how does that break when we never put any dishes with food in ours? Anyway it's fixed for now! Thanks
This was my issue as well. We bought our house a little over a year ago. It had all new Samsung appliances. In this year we have replaced the microwave, the fridge makes loud cracking noises and the ice maker no longer works. And the clothes washer has had a recall where it crashes around when un-balanced (Samsung's response to the recall was to send out a sticker that reminds you to use the bedding setting for bedding).
Now this issue w/ the dishwasher. I would never recommend Samsung appliances to anyone. Steer clear.
Look for missing plastic tabs on the upper rack.

Perfect solution and the step-by-step with photos out on http://303lurch.com/?p=164 were super helpful. Found two cherry pits and a piece of plastic in the water pump.
June 12,2011... i think a lot of the issues regarding noise and cleaning issues are related to the water sensor assembly. Small white plastic device on left hand side of dishwasher when pulled out. we had this dishwasher 3 months, the upper plastic clips broke, then the loud grinding noise, - called for warranty repair, in meantime got a code 9E - low water level. Repair man came out, pushed some special sequence of buttons and it never gave him the history of the 9E code coming up, but we ran a cycle and sure enough it came up. Repair man came back 3 weeks later with parts (yes 3 weeks - upper brackets, water sensor assembly and a new bottom tray - as there was a thumping sound). Repair man found some plastic shavings in the water assembly which may have caused the fault in the sensor reading water level. dishwasher fixed, very quiet now, and dishes are super hot to touch after cycle and clean - if you place dinner plates apart - tines are too close.
prior to being fixed - dishes would have a few water dirt stains, and dishes were not completely dry. Now they are dry completely - even the plastic utensil holder handle. I also made sure the drain hose was fastened up high to top of inside cabinet. i still would not recommend this dishwasher - but want to help those of us who are stuck with it !! hopefully this helps.
Perfect advise above. My dishwasher was making the same rattling/grinding sound. Did this and a small piece of plastic came out. Just ran it and it is perfectly quiet again. Thank you!!! Glyn from Texas
I removed the white plate from the bottom of the dishwasher, removed the drain line with a pliers, and found the missing piece of broken gray plastic from the upper dish tray. One of the other plastic tabs holding the tray was also broken and barely hanging on.
Thank You All, especially fultondsan for providing detailed instructions. I Probably would have figured it out but I would just as likely have made it worse first ;-)
The new Samsung dishwashers have to be accessed from underneath. I posted a video: Samsung dishwasher grinding noise FIXED
Thanks for this thread. I had several tabs break off, but only found one in the discharge pump. That was the source of the noise.
We just had the grinding noise in ours yesterday. I pulled out the dish washer and removed the bottom white plate. I checked the drain hoses and found nothing. You can twist off the purge pump however and lo and behold I found a grey cap that covers the acre holes in the side of the dishwasher inside! That was the source of the grinding as it was hitting the impeller of the purge pump. No damage done. Replaced the hose and plate and everyone is running well now. Beware of small parts getting into the grinder or purge pump of these machines. It seems too easy for thing to get past any filters.
I did all that was described and the SE error persists. I should mention that it's the second time this happens to me. the first time I cleaned the small white plastic device on left hand side of dishwasher as well as the black hose leading to it so I hoped to do the same today ... but it does not help. it seems like the water pump is not being turned on to pump the water out meaning as soon as the white tray is full the dish stops and the SE Error appears.
Any help will be GREATLY appreciated!

Great solutions - the step by step with photos herehttp://303lurch.com/?p=164 really were a huge help.
Whoops... didn't realize that my comment actually posted below. :)
YOU WOULD THINK, Samsung would issue a repair part or warning. My Dishwasher had the same problem.
Thank you. The link was very helpful.
