    Thanks everyone. Will have a read of the manual and adjust myself. I think I'll skip the service for now as well [emoji106]

    Good to see you've got the machine working....
    I'd say you've given it a pretty good service yourself. It's working, and if it aint broke, why go have it fixed? Turn down the pressurestat to lower the heat till you're satisfied, and enjoy the coffees.

    That manual has been available here in the Pointy End Documentation Area for over a year and a half.

    Everything you have done already is much trickier than adjusting the pressure/temp.

    I have been working on a Domobar Super (slightly different model). Adjusting the temp/pressure is pretty simple. Just remove the top cup tray and the black plastic cap to get to the pressure stat adjustment which requires a flat screwdriver.

    If you haven't found it already 1st Line coffee has a great manual for Domobar Super.

    I have attached it as it may be some help as it has a section on adjusting pressure and also a pressure to temperature guide. Aim for 1.1 bar on the left gauge as this should equate to 93 degrees Celsius for water temperature.

    Those two things march in lockstep and thus both can be addressed by tweaking the pressurestat down a notch or two.

    Thanks everyone for your help and advice. Checked that water was at least travelling through one of the pipes leading to the group. It was but looked like there was a partial blockage. Took the group apart and the two main pipes connected to it and descaled everything. Machine is now working as it should, maybe a tad hot and pressure is too high. Thinking of getting it serviced anyway just to make sure everything else is OK and to have the temp and pressure properly dialed in.

    Really grateful for all the knowledge on this forum. Thanks again.

    I think that will be your problem, in that 3way. Dislodged wire, sticking plunger.. something in there.
    Im not sure of it's modes of operation...

    What about removing the 3way all together. Then if pump runs and pumps water out where the 3way is, you have water to the group.

    I think this is the group you are looking for. If I had to take a guess I'd say all of those years of this machine sitting around I'd say something is stuck or seized keep doing what you are doing stripping and cleaning reassemble and test.

    Yep, M-GT is correct if you have a non-leva Group...
    Thought you had a Leva E-61...

    Those parts are the inlet valve that is operated by the lever cam - a non-lever group like yours won't have those.

    The photo of the front is from too high an angle to show it, but there should be a little stainless steel 'box' under the group head that covers the 3 way valve, probably held in place by the exhaust tube that points down into the drip tray. Unscrewing the exhaust tube should allow the cover to slide down and off the 3 way valve, then there will probably be a thin 14mm nut that you undo to remove the coil to access the terminals to test it.

    Juat wondering if this is what I should be seeing after removing the shower screen and the group sprayer? Also, I know my machine is slightly different to this as it does not have the brew lever, but I dont have parts 6, 7 or 8. Should I?

    Is there any danger in me running the machine with the brew group detached to see if the water is at least getting there from one of the two pipes that connect to the brew group?
