    EM6910 Sidecover removal

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    My 6910 has developed a small leak so yesterday I whipped the back cover off and discovered that its just a loose swage fitting at the bottom of the copper tube :-/
    The problem is that you cant get at the fitting without removing the metal side cover which I cannot figure how to do ::) The screws at the bottom come off easily but be damed if I can work out how to get the top free.
    Anyone have some experience with this?

    Remove from all power before attempting any thing... Water and electrons do not mix with great outcomes...


    Remove the top Anti tamper screw... You will need a good quality torx number 5 ?? Mine says 320T


    Then after ya repair ensure the safety has been maintained and perform an EST in accordance with AS3760..

    Once you remove the safety lock or any tamper proof screw you have in fact breached the equipments manufactures risk management approach..

    Thus even if reconnecting a non electrical item... You could possibly cause a unsafe situation...

    As due to licence and a duty of care, ( implied or direct) it is required that I advise you of the correct process to follow before putting said item back into use....

    Electricity can and does kill. Other CSs have been bitten doing simple repairs.. If it happens.. I wont give it a second thought...

    What is another one, to a list that now exceeds the fingers on both hands..

    Re: EM6910 Sidecover removal

    I saw the torque spit but was hoping the side panel could be removed easily. 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.
    I will make two inferred observations from your above replies
    1) There is more weight than I had initailly attached to your forum name.
    2) You are a sunbeam repairer.
    Are either correct?

    You and other have the right to ASSUME what you wish *;D *:D *;)

    As to the two points you raise..

    Q1: Weight

    A1: Actually I am about 68kg soaking wet *::)

    Q2: Sunbeam repairer

    A2: Wrong if you mean I have any formal association with Sunbeam or its agencies either now or previously...

    If you mean I repair coffee machines as a hobby and some might be stamped Sunbeam.. Correct.


    If you really want to know me... *Try reading the last 30 odd posts of mine..

    Angry / Mad / Frustrated / *Old / Had a gut full / Love to stir / *Suffer fools - NOT... *But above all like my coffee.

    As stated in another post... The truth can be much stranger than your best attempt at fiction... *

    Those that know me in person, know me better.... *But like PC said *there are .. Both Sides Of The Story.... Or BJ with "The Stranger"... *8-)

    Re: EM6910 Sidecover removal

    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.

    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.

    TG... Why is this so ? It is something I have noticed on occasion.. Quality = Rude or is it that many just do not get it ?

    PS.. I guess if enough think I am rude... Then I must be... But I think ya last line says it all...

    PPS. Yep we lost another employee only the other week... First line RCA - Almost with out fail... Fail to disconnect/check and Fail to use PPE... RCA - Familiarity breeds contempt.

    Its because we are used to delivering factual information, which tends to not be as "soft" as normal speech.




    AND they just dont get it.
    AND were both rude old bastards.

    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 :)

    Read this thread with great interest. Strikes me, that rudeness could be implied more forcefully by those with knowledge, when they dont answer future requests for help. Lets all be nice, and realize that tone and communicative intention are not obvious in the written word. Imagine future replies from our collective iPhones....

    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... *:o

    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 ;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 :o

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

    I doubt that Im like the academics you deal with, I live in the real world :D
    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.

    1: I am a prick ;) Well actually my wife would suggest an ass hole at times ;D She only just had a go at me, because I tore strips of a very close mate over how to use Adobe and generate interactive forms :-)

    But all good intentions, just loosing patience and where too many just just EXPECT... And expect it instantly..

    A: Once raced GS500s - but no killer instinct in a tight corner. Love boxers and when had to sell due to kids due and a house... They got BMW as initials :D Two speeds Full stop and flat out.

    B: F&T as a trade, Dip in Coms and Electronics, Electrical Quals and Licence, Time with teh Navy and at sea, Builders offsider, Gold and other mining - underground and surface, Teachers Aid - Manual arts, Silver service and Bar - Hospitality, Professional shooter and destruction of vermin, ARCBS - Blood product and Cold chain management - Papers etc etc etc Vaccine management papers etc, Service for Haematology, Coag, Blood Gas, Flow and Blood banking etc etc etc (AU,NZ,HK,US, South Pacific etc), MCP for MS and NT, Contract Management and Tenders - Writing and Procurement; WHO support in PNG, FiJi and China, PC3 and PC4 audits and investigations, Public health and Forensics. Post grad in Health Management, External Auditor (Quality), NATA experience and Metrology - Calibration, Middle Manager - Biomedical etc etc etc

    Then there are other hobbies, experiences, wife number 3 and other things that are NFP.... Life and death are cheep and more so in some places - than others. Every day is new and teh past can not be undone.. One must move on, if and when a new day is offered.

    As brief as I can get :-?

    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 :o
    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 :-[

    Did you completely remove and disassemble the solenoid valve to clean it?

    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
    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..

    PS. Matrix... How is yours going and your Group Handle ?

    watch this vid. At the 38sec mark is the "pshht!" which is the relief valve letting go of the built-up pressure in the head and exiting it to the drip tray below. You can see it happen if you remove the stainless tray.

    Does this happen to yours?

    Now I feel like a real goose. The rubber thing never seemed to work. Im gueesing I was using it incorectly :-[

    All the lines bar the galley through the head are flushed. I was surprise at the lack of scale but thats not siurprising hink9ng on it now, its hardly had any water through them if my guess is right.

    I have access to an ultrasonic which is why I threw it into consideration. What are the pitfalls I should consider before deciding whether to attempt it?

    For one ya need to know what your cleaning.. Sounds silly, but nothing worse that putting in ONE item and then finding springs and little balls etc.. Opps how does this all fit back together ;)

    The rubber blind... Just blocks for a moment and as your cleaning tab dissolves, it also releases some of teh pressure and cleaning fluid flow through the group... When checking ya Gauge... Either the Rubber a OR double floor used... Then in manual after a min or so teh gauge will reach a value... That is the SB sweet spot... Do a search as there is plent to read up on...


    So what is the ACTUAL problem that you believe, your having...

    There is a blockage in the head in the line b/w C on the diagram above and the rear of the head. I disconected and cleaned all the copper lines b/w rear of the head and the 3-way. I can blow air through them but not from rear of head through to C.


    Two symptoms: no reading on pressure guage & pressure not released after in head after brew is stopped.
    I cant blow air from B through to C

    Pic again to make it easier :)

    ps you cant see it from this pic but copper line runs left-to-right out from the 3-way/soleniod straight to the back of the head.

    I am correct in thinking that when the brew cycle is stopped that the solenoid should open allowing the pressurised liquid in the head to run out through C, past B, through solenoid valve then into the drip tray?

    are you getting any coffee through when you try and pull a shot as normal?

    And what happens if you try for HOT Water... If that little spring valve in the head is playing up you will have all sorts of issues.

    Everything is working as normal except for the pressure relief in the head when you cut the brew cycle. This is ok if I get it right as the liquid can still trickle out the group handle but if I overdose or grind too fine it all stays under pressure with the resulting spurt of grinds everywhere when the handle is released. Also makes inspection of the puck difficult. Im still making coffee however and when I get it right it is as good as ever. The gauge is registering no pressure but it does work (used martrix air trick to check it) so it all points to a blockage in that line b/w C and B.

    Im fairly certain the blockage is in/near C just where the tunnel does the right angle turn to the rear of the head.

    The spring/non-return valve in the centre (A) was removed and cleaned. It appeared to have no problems.

    The fact that I can still make coffee has me tossing up whether I should live with it as it is :-/ However now that I know its not meant to be like that itll play tricks with my head :D

    giggled like a schoolgirl... *So true.... Many a time I have persisted and ended up mush worse off and then questioned my intent *;D

    However, in this case, it is about getting a dry puck and allowing excess pressure to be safely managed... *Thus I would persist from a WHS point... *

    As to teh gauge working... That is a side issue *:D

    UPDATE: With teh system OFF - Using my small compressor; air was input at C and the gauge moved slightly, with the excess coming out the drain..

    Thus I can only assume that there is a blockage in the head and or tubing from the take off for the gauge to the head...

    CLEAN and SUCK and BLOW - Do this for the actual components ONLY... Other wise you could move the offending crap into another section and cause further issues...
