we started to get error codes, all related to drainage, after about 1 week of use. on two occasions the dishwasher emptied its contents onto the floor. 
the samsung engineer due to fix it never made contact despite us chasing them. so we arranged for a replacement.
we have had the replacement for 2 weeks. we have started getting error codes and  again the dishwasher dumped its contents onto the floor. twice.
a little research shows i'm not the only one to experience these problems. it'll be replaced by dishwasher from another manufacturer.
