i wanted this washer for months... it was so pretty and with the samsung name. i have had it for less than a month and it is mediocre at best. my 18 year old whirlpool did better. i don't over stack and i rinse my dishes well before loading. i use the rinse agent as too.
pros: pretty, quiet
cons: spots on dishes and glassware, food left on dishes on lower and top racks using the full wash that is 2.5 hours long. no drying system... at all... it opens and air dries.
maybe linear isn't something they have worked out.
