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.
The Otis Gen2 is a marvel of engineering. It replaced the heavy, clanking steel ropes of the 20th century with flat, polyurethane-coated steel belts. It is smoother, quieter, more efficient. It is the sound of corporate friction reduction. The aesthetic is deliberately sterile: brushed stainless steel, recessed lighting, controls that request rather than command.
