Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Wash — WaterWall (top tier)
- WaterWall uses a sweeping 'wall' of water from a moving bar across the tub floor for intensive, even coverage — a premium wash. If the WaterWall bar is blocked by a fallen item it cannot sweep, which is a common cause of poor cleaning on this model.
- Drying — heated + AutoRelease door
- Heated drying plus AutoRelease Dry auto-opening door; intentional at the end.
- Filter & codes
- Manual filter must be cleaned periodically; LC = leak sensor; drain codes point to the filter and drain hose.

Questions that only have an answer for the Samsung WaterWall DW80M9550 dishwasher
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
My Samsung WaterWall dishwasher is cleaning unevenly.+
The WaterWall system sweeps a moving bar across the tub floor, so anything that has fallen through the racks and blocks that bar stops it sweeping and leaves areas uncleaned. Check the tub floor for fallen items or utensils jamming the WaterWall bar, clean the filter, and make sure tall items on the bottom rack are not blocking coverage. The bar must be able to travel freely for even cleaning.
