After 13 days of starting the Cooldown of the Liquefier A, today the level sensor indicated that the Dewar A has started accumulating liquid. Notice that the outlet flow actual value is around ~13slm although FCAQ is still set to 24slm.

In the morning we noticed that the Liquefier A switched to the "Liquefy" mode automatically because the condition "Mode end: Dewar level" 5% was met.
The liquid level is ~24L and artificial blockage appeared. So, the Dewar pressure and heater were adjusted to get rid of the blockage.
