less than 3 months into using the dishwasher it starts giving us trouble. mid-cycle it'll get stuck and won't progress. then we run it and when we wake up and it's back to the original start time like it never ran. called samsung and they send someone out but the problem is there is no error code and it's an intermittent problem so it doesn't happen when the repair person comes.  he says the waterwall arm was loose, fixed it and said it would be resolved.  two weeks later happens again.  get the same questions and now i have another repair person coming.  samsung doesn't seem likely to replace this unit, just keep sending repairmen. this shouldn't be happening to a unit less than 6 months old. i’ll likely end up buying a new unit (different brand) and lose $900.  should have bought an lg.
