    Chances are it was a very small film of scale deposited as the water remaining in the group head passages (after factory testing) slowly dried out while the machine sat on display - the jet being the smallest orifice in the system would have likely remained a film of water across the orifice (due to surface tension) and as the water dried, the jet orifice would have gradually plugged up with dried mineral deposits. I've seen it happen on several brand new machines, both commercial and domestic, and they don't always have to have been sitting for a long time for it to happen.

    Chances are the tool he used to clean the jet was a set of tip cleaners for oxy/acetylene welding torches, that's what I use. Perfect for cleaning out a wide variety of small jet orifices.

    Yes, I even quizzed my tech friend what it was for who told me, verbatim, "to prevent this kind of issue".

    The above image is looking at the gicleur jet inside the mushroom nut,
    Once the mushroom nut is removed, the mushroom itself along with the gicleur can be lifted out and the gicleur unscrewed from the mushroom and cleaned out with a toothpick or similar.
    On a new , unused , machine i would not be surprised if the blockage was some form of debris, sealing compound, metal particles, etc left over from assembly and moving the m/c could have loosened up some of this and let it flush through to the gicleur area.
    There should be a filter immediately above the gicleur to prevent this kind of issue... was there one installed ?

    Not sure about other machines BB, however, the area photographed is the top of the E61 assy and my Galatea is finished similarly, seems they are all like that, must admit it's the one cosmetic aspect of the machine that pisses me off, Mr Bezzera please take note.
    Fortunately it's pretty well hidden from view and is only really noticeable when you working on the top of the assy, removing the mushroom etc.

    Certainly a problem/fix to keep in mind.

    Thanks, I'm stoked, and the 3 shots I've been able to pour are something else compared to my old Oscar.

    From the sellers description it was brand new, and it certainly looked that way, (still had protective plastic on the chrome). It was manufactured in 2012, so it wasn't sitting on a store shelf for years as I thought it might have been.

    The manual didn't mention anything specific regards to a start-up procedure.

    I'm still not sure what the actual blockage was, I tried taking a photo but it didn't really turn out.

    Solved, thank you all for your help. I had a mate that's a coffee tech sort it out, it was a blocked gicleur. He vouched for it being a new machine, but said it's not often you'd see it blocked like that if it hadn't seen use.

    The pump is turning on and pressure rising to 12 when the levers lifted right? The problem is not electrical or OPV

    It could be cam attached to the lever is not lifting the valve to let water out, i.e. a broken cam shaft
    or Giclcuer blocked...
    Thanks for the reply, man this thing is a puzzle together open.

    The lever feels like a sensible amount of resistance required.

    Lid off and all electrical connections look fine.

    Oh right, my mistake. I was confused. I'm going to edit the earlier post, don't want to confuse others more than I already have.
