There is a detailed set of instructions about how to post a photo on this forum in the "welcome" section. It sounds like your Centa rollers have broken up. Can you re-start the engine with the starter motor or does it just whirl over without turning the engine? If it just motors over without any engine cranking, they have failed completely. Total failure can happen if you ignore all the vibrations, noise and rubber smells and chunks of rubber roller on the floor.
