But in practice, they proved impractical and time-consuming, leading down a path that risked unnecessary teardown of an otherwise serviceable machine.Instead, it was practical experience—knowing where these units typically fail, recognizing subtle symptoms, and understanding how the system behaves under real conditions—that led to a fast, targeted fix. No full disassembly. No wasted hours. Just the right call, made at the right time.
