7693A Autosampler Failure Codes

Lately, an Agilent 7693A autosampler (model G4513a) intermittently shows error codes. Does anyone know where to find a list of error codes / failure codes? I cannot find any Agilent document with these codes and possible corrections.

 

Status Screen:
ALS Failure State: Preparing Samples
ALS Failure Code 245: Autosampler front tower plunger error

 

Last time the ALS threw a code, I performed troubleshooting by swapping out cables and towers between our two GC systems. The other GC tower worked on this system, and visa versa. After all the swapping and turning GC system off/on, the code eventually went away. Not sure why.

 

The tower intializes the same as the identical one on another GC system.  The green Ready light is on.  The instruments and computer have all been cycled off/on.

 

Any advice will be greatly appreciated.
