Remember the gauge connected WHERE ! Thus there is also a dwell time as pressure builds in the Boiler (Head / air space) and thus the larger the brew boiler the longer the dwell time.
In effect it adds a slight pre-infusion by default. It starts to pump, water reaches the puk BUT at this stage it has not pressurised the boiler. Mine usualy takes a few seconds (6 to 8) to build up and you will here the pump change as teh load increases and then it will move from 4 or 5 bar to 9.
