    You make some good points and a lot of assumptions about my risk taking/mechanical knowledge.

    Forgive my response but your replies although being rather informative could be taken as rude.
    Without knowing your risk taking/mechanical knowledge, it makes sense to me that AM would play safe and ASSUME you know nothing.

    Then again, we both have a quality background and I too can be perceived as rude occasionally.

    Better to be shocked by AMs language (but alive) rather than have been spoken to politely but (shocked and) dead.
    I understand that It was the presentation/tone rather than the assumptions that I took issue to. AMs first two posts were terse, his third showed some humanity. Im quite prepared to believe that AM meant well and thats just his style or a bad day or whatever. The fact that he has responded since points to that.

    Ill lead onto another point Im a research scientist so I understand the need for the concise presentation of data but facts dont have to be presented in a drab manner (that can be left to accountants ;D). just some food for thought
    INTJ... Should have realised...  ;D    

    Only one line in the second post was a bit pointed  :

    And in-fact - the info in my first post was concise and to the point..  You asked / provided no background and was an unknown poster - you got the answer and then you FLAMED...  

    I may be an ENFP but often get tired of people that do not RESEARCH or look for the answers that are already posted...  Lots of PICs and instructions including PDFs as to how to pull the EM6910 apart..   ;D

    Be thankful ya got me on a good day :P and that I did not just direct you to a STICKY -  http://coffeesnobs.com.au/YaBB.pl?num=1248646363

    Besides most of the Scientists, PHD, Masters and researchers I deal with every day understand Quality and a direct approach - As per TGs post.  In fact, any thing less blunt is just NOISE to them.

    The fact that I may have / did have / am having a bad month - WORK / Family / Multiple Deaths - Yet still attempt to assist with  timely advice while considering YOUR and OTHERS safety  - Well.. thats just me.   I am also  dyslexic, bad tempered (going off teh cigs), old, no humour, sick of trying to revive dead people; BUT am 100% happy with my self....

    If ya not happy with me or my approach ...  Take a Cement pill - Quick Set I would recommend    and then report to the Forum Moderators  :-*

    Now, on that note; my Assignment is waiting, along with others that may need support / advice and may be; they will appreciate it

    I need a tripple shot to get the bad taste from my mouth  ;D

    Over and out - Forum Ignore filter Activated.

        Actually Im an ENTP, so your close-ish
        I doubt that Im like the academics you deal with, I live in the real world
        Now you have me intrigued, what do you do for a living?

        I have done a search and found little of use wrt diagrams etc. I have a manual but it is useless (you refer to it yourself in another post ), just a big parts fiche : The link here does not seem to work.

                  Brewman you can be sure AM was just giving responsible advice.  I wish Id listened to him before attempting my 6910 repair.

                  I too was working on a non-electrical fault. After turning the machine on & off several times whilst testing, at one stage I forgot to turn it off. Result?  A nasty zap which triggered the safety switch AND a cooked thermoblock.

                  I dont think anyone on CS is more generous with their time than AM is.
                  I am happy to report back that severly zapping yourself on a La Pavoni Pub does not cause any damage to the machine itself. :-/
                  This was while adjusting the opv, and accidentally brushing my hand over the element plug.

                  Any advice that will help you from killing yourself is great in my book

                    Thanks AM



                    Everyone can be assured that I do not take the danger of electricity lightly. A long time workmate (an electrician) was electrocuted when we were both starting out, in a very nasty accident He is lucky to be alive but 20+ years later he still has health problems as a direct result

                      Re: EM6910 Sidecover removal

                      Ok sidecover off and fitting nipped up (it wa sthe one at the bottom od the copper tube that feeds the steam thermoblock) Thanks agian AM. Martrix will be served one of my best beers when we meet ;D

                      The story now continues -
                      I went to Jetblack for one of their home barista courses last week (excellent course from Deb and Charlie who know all the ins and outs of the various domestic machines. I can highly recommend it)
                      Charlie noticed that the pressure guage wasnt working. It stopped in the first week we owned the machine and I figured that the pain of losing the machine for 1-2weeks while it was repaired was more than the pain of living without a guage. Once we started pulling shots Charlie observed that the three way valve was not working. Im now convinced that the two are related. The first option was to leave the blind filter under pressure overnight with the machine in standby mode in the hope that the cafetto and pressure would release the blockage. All this achieved was to deform the blind filter
                      While the cover was off I used the link above to check a few things. I removed and dissaembled the 3-way valve which was in surprisingly clean condition. I clreaned it anyway
                      I then back-tracked using Martrix air trick and located a blockage in the group head bw C and the swage fitting at the rear of the head. Ill pinch his diagram to explain

                      When I blow through B. Air it doesnt come out C. I had the 3-way valve disconnected but Im fairly confident its not the culprit as I can hear the solenoid clicking when I hit the brew button and Ive just cleaned it internally.


                      Im right in thinking that air should come out C. yes?
                      I spent all afternoon squirting cafetto down into the orifice (from both ends) with a syringe and poking with s/s wire. Left it o/night with cafetto soaking but still no air would travel though. I reassembled this morning because I wanted a coffee and I was hoping in my heart that a backflush would blow out the blockage after the attention of yesterday. But Im still in the same situation.

                      Im hoping to draw on CSs collective brainstrust to offer me a better way to unblock it or am I just gonna have to bite the bullet and buy a new group head?

                      The machine is two years old so its well out of waranty and Im not prepared to put up the fight with SB that its a waranty job because it occurred during the warantee period - two chances Id get a good result from that one I reckon :-[

                          The SB blind has a hole in it for good reasons... If you left a normal blind in it... Naughty....

                          Rather that forcing any crap further into the system... The trick is to work in the reverse ... IE. Suck via a vacuum system or apply pressure from the other end..

                          However all pathways need to be manually open as you dont want to do this when the system is ON..

                          Matrix took some time and will confirm that at the end of teh day.. It is rather straight forward, but you have to take ya time and no SHORT CUTS... No matter how good they might sound..

                          At the end of the day.. Matrix / Myself could assist but or time and getting it to us is teh issue...

                          Keep working on it... But slow and steady... Also do not break the fine tubing to the Gauge...

                          I have done about 8 major repairs and all have been basic problems, often due to misuse or lack of cleaning (Correct cleaning that is). I still try to short cut and get caught every time...

                            Bman, I would suggest first you disconnect you pressure gauge line (at B in pic above) and then blow compressed air through it to see if anything registers on the gauge.
                            Be super gentle with this copper line as it is hollow and will only take a few bending sessions before it will develop a crack.


                            If that checks out with no major leaks then I would be removing the solenoid valve and clean it as per my post. Make sure all the little rubber items are moving correctly, study the little bugger and soak, clean, soak clean in Cafetto.

                              Obviously I am naughty, the crap will be well and truly forced in now :-[ Ive only had a blind filter for a few days, the machine didnt come with any - unless you mean the dual floor baskets :-/

                              Would some time with the head in an ultrasonic bath be worth a shot? The other thought I had was contact cleaner :-/ You can squirt that down the orifice with the tube applicator.
                              I have a compressor so Ill take the blow from the back option but I reckon its (the blockage) been there for two years and has had plenty of time to bake itself in. It wont be easy is my guess. Maybe the new head option would be worth it for the saving in time/aggravation

                              The guage is working which is why I reckon the blockage has been there since the dial stopped moving. Ill remove the head and go from there.

                                The rubber blind is usually inside and attached to the rear door... Or you can use the double floor baskets as it does the same thing..

                                A solid Blind is a NO NO on these units...

                                I would be cleaning and flushing all the lines prior to replacing teh head... That could be more than the unit might be worth..

                                I do use an ultra sonic but one needs to take some care with some items and the removal and refitting is where YOU / ME introduce a fault and they are the worse kind.

                                Of to Ballet so will check back in a couple of HRs..
