Paolo5 there is an issue on some machines with the pump not activating automatically when the lever is pulled down. Mine has that issue. A part is in transit to me from Antony at Casa Espresso to rectify that. It slips on over the rear of the paddle area I think. It may be that your issue is related. Suggest you contact Antony. Any easy fix apparently.
It hasn’t been a problem for me because I’ve simply activated the pump by pressing the right paddle towards the machine. That said, I’m still looking forwardto having rectified.
Paolo I’ve been using the 9barista this last week almost exclusively so my memory of the Nurri is a little hazy but as I think about it I seem to recall that I am often deactivating the pump after I lift the lever, by nudging the right paddle towards me.
I’ll fire her up tomorrow and report back.
