G1600ax EL5207 error
It started giving me the error in the middle of the night after all runs were completed. Now it does it in minutes.
I went through the adjust offset diagnostic macro and the pressure is able to get to 900 mbar HP 400 mbar vac within 2:00. So I don't think the pump is bad or there is a leak.
The buffer bottles and o-rings look fine. I tried switching bottles.
