Same error code has happened to my SVL75-2, just now. Dealer says it is a starter drive inhibitor code. It is probably a safety feature to protect the engine, but that doesn’t help me solve the problem.
Thank you. I had the same problem with my tractor. I followed your instructions and the problem is solved. I have been going through the fuel system, drained tank, changed pumps, but I had not disassembled the water separator. Thanks, again.
