    I've just had a similar issue with my Technika. I spoke to Renzo at Di Bartoli who went through a few simple checks, in the end advised to descale and popped a bottle of descaler in the post. Took less than 10 secs on the first descale flush to clear the blockage. I hope your issue clears up just as easily.

      I had a play with it in the shed today, took the back and sides off to get a closer look at the water circuit for potential blockages.

      Removed the line to the pump and blew it out with compressed air, then the line from the pump to the solenoid, the the lines to each boiler, then the line to the steam wand, then the line to the group head, the fully disassembled the group head, cleaned it and greased it. Removed the screen and the little thing under it with the 2 small holes, blew them out also. I didn't do all the lines as I didn't want to remove the boilers so the lines from the bottom of the boilers didn't get cleaned.

      Over all there was bugger all scale in any of the lines. I was really surprised how clean they were given the 12 months of daily use.

      Not confident it was fixed (as I didn't really find anything concerning) I reassembled it and plumbed it back in and turned it one, still no pre infusion flow and 30ml in 16 seconds same as before.

      I don't think it is a pump or motor issue as pump pressure is still getting up to 10 bar, slightly higher than what it normally does with coffee in the PF, it normally gets that high when the blind PF is fitted and doing a clean suggesting a blockage or partial blockage somewhere after the pump.

      Before I box it up and send it to a someone to inspect i was thinking of doing a full system descale using the inbuilt tank to pump descale solution right through the pump, boilers and all lines. Is this a good idea?

        Sorted, thanks to the help of a forum member who steered me in the right direction, much appreciated.

        found the jet in the top mushroom bit blocked up. I pulled this out yesterday but didn't strip it this far.




        What it now looks like, water flow is so much better, 30ml in about 4 seconds

          Wooohooo , glad to be of service... :-) Hopefully you tried that option before my other suggestion ? (checking the water valve mesh filter) ?

            yeah didn't bother with the other one after I found this. It was easier to get to. Thanks again

              The mushroom valve should always be the first thing that gets checked if you suspect there's a blockage. If there's scale present this is where you'll see it most easily. If the group head is clean then your problem is elsewhere.

                True, but with the ECM machines it can be a little less obvious how to get to it, they don't have the usual 22mm nut on top of the mushroom, instead you have to separate the two halves of the mushroom using the upper 36mm nut and the lower half which has 19mm flats machined into it

                  Good info for ECM owners. I'm sure it's still easier than disassembling other parts of the machine, so it's handy to know what to look for.

                    Can I just clarify where exactly this valve is located? I dont seem to recognise it (though, that might be because I have never stripped my technika apart)

                      This screws into the top of the group head, the main nut is 36mm and the machined flats can be seen on the valve body. Seperate these and the little Jet and screen is inside
