The travel solenoids were getting an intermittent and unpredictable signal from the HWH control board. Cleaning connections and fuses resolved the issue, although the system should be monitored for future flakiness. The intermittent signal could be caused by a failing solder joint.
In bigger picture context, the process to follow with any leveling issue is to FIRST determine if the problem is electrical or pneumatic. On HWH systems, the first step is to check the magnetism of the solenoid that is supposedly engaged. You can go to the trouble of unplugging the solenoid and measuring the voltage, but the quick sanity check is to place a washer or small screwdriver on the top of the energized solenoid.
