Back det H2 flow

In my 6890 GC-FID appears the status message: Back det H2 flow. It is a random message and when it appears I have a lot of noise in my chromatogram

I have cleaned the detector, the jet and reinstalled the column but the problem appears again. I also checked the leaks in the line and it is ok.

I have another FID detector in the front and it Works correctly.

Any advice? What should I be looking at?

Many thanks
