Error Code Explained
What Does the Viking Spray Arm Obstruction Error Code Mean?
Viking Professional dishwashers use multi-level spray arms to distribute wash water throughout the tub. A spray arm that cannot rotate freely — due to a rack item blocking its path — or one whose jet holes are clogged with limescale or food debris will produce uneven cleaning with some areas of the load consistently coming out dirty.

-
1Rack Item Blocking RotationA tall item in the lower or upper rack is physically blocking the spray arm from completing its rotation.
-
