Why does my Kohler generator show error code 16 even with a full tank?
This usually indicates a fuel delivery problem such as a clogged fuel filter, blocked fuel line, or faulty fuel pump. Check each component as outlined in the steps above.
Can I reset error code 16 on my Kohler generator?
Yes, after fixing the underlying cause, you can reset the error by turning the generator off, waiting a few minutes, and then restarting it. If the error reappears, the issue is not resolved.
