Troubleshoot: couch will not go up/down and oil leakage
Use this fault-isolation flow when the Aquilion 16 patient couch's vertical (lift) drive won't raise, won't lower, or shows hydraulic oil leakage — the source manual treats all three symptoms as one linked flowchart across two pages.

Personnel
1 technician · Intermediate — hydraulic + electrical fault isolation on the couch vertical (lift) drive; mixes a live-circuit check at mains level (source calls for >=180 VAC, and a rated-voltage check at the solenoid valve) with mechanical observation (pump noise, oil level, sinking rate), and ends by handing off to dedicated replacement procedures for the tilt encoder / solenoid valve / hydraulic unit (skill assessment derived from procedure content — not an OEM-stated skill level)
