    Have you made sure that the flow is fully stopped when the needle valve is closed?

    If not, loosen the retaining screw for the handle and lift it up a little so you can fully close the valve.

    If you are trying to slow the flow down you will find that you will only need to open the valve less than a quarter turn to achieve about 2 bar with about 1.25 turns for full flow.
    NAILED IT! thank you, full control restored

    Definitely doesn't fully stop. I'll look into this.

  • Profiling advice please. Using my ECM Technika V profi with flow control

    Hi Team,

    I'm after a little advice about using my coffee machine.

    I recently upgraded from an ISOMAC mondiale to an ECM technika V profi, which have been wonderful.

    It has a flow controller fitted which I am just having a little hard time getting my head around. Perhaps a coffee snobber might be able to help with.

    Essentially it doesn't to matter how "open or closed" I have the flow control it always goes straight to 9 bar.... If I run the group head with no handle attached I can see a obvious reduction in flow as I close down the flow controller, but it certainly doesn't shut it off completely.

    The best I am able to achieve is stalling the pressure for about 2 seconds in the first 4 seconds by starting the shot with the flow controller (half turn open) then once I see the pressure engage I turn the flow controller (fully closed). This give me 3-5 seconds of pressure between 3-6 bar before the head equalises with the pump at 9 bar even with the flow control fully closed.

    Overall this doesn't seem like much of a difference from having the flow controller fully open from the beginning of the shot (getting to 9 bar in 2-3 seconds). Am I doing something incorrectly?

    For reference my grind seams dialled similarly to when using my Isomac. I'm using 15g VST basket dosed to 17.3g & extracting 25ml in 30 seconds.

    Thank you in advance.
Working...
