In 2018, Otis introduced an enhanced polyurethane formulation (Gen2 Premier belts) that significantly reduces the scratch phenomenon. If your building still has original "blue label" belts, you are in the high-risk category.
In strict Otis service literature, there is no single fault code labeled "Scratch." Instead, used by field mechanics to describe a specific audible and physical symptom: the sound of steel-on-steel contact within the Gen2 drive system. otis gen2 scratch
