Samsung DW80R9950US Repair Guide
A premium Samsung built-in with Linear Wash, where the spray bar travels the length of the tub rather than rotating. Extremely quiet at 39 dB, with a moving assembly no conventional dishwasher has.

Tech notes
Linear Wash adds a travelling spray bar on rails, and debris in the track produces uneven cleaning that mimics a pump fault. Inspect the track before condemning the circulation pump.
