    em6910 steam issues

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    After a couple of years of faithful service, my em6910 has developed a problem with the steam side of things.

    A colleague filled up the water tank this morning, but i dont think it clicked in properly - i poured a shot which struggled for water but got there + then when I went to use the steam wand, it didnt pressure up properly and is now all but dead. :(

    Symptoms now are:
    steam wand heating but no pressure. (just very weak pumps)
    Group + hot water pump working fine.

    I called SB repair centre + the guy told me it may be any one of 3 problems:

    blocked = $90 - 115
    new circuit board - $270
    or pump - warranty


    is there anyway of knowing what it is before i get taken for a ride at the service centre?

    Thanks in advance, Matt

    Hi Matt

    There have been a few threads about steam blockages in 6910s. A search would help, just remember to change the default search range to something longer than the default 1 week.

    This may get you started : http://coffeesnobs.com.au/YaBB.pl?num=1232674232

    No doubt some others will contribute also.

    I have had several EM6900s where the Steam Wand failed...the current EM6910 still working beautifully. While the "reliability" of the EM69xx is debatable, from my experience the Sunbeam support has always been top notch so hopefully, being taken for a ride wont come into the equation.

    If you ever fully choke an EM6910 and keep pushing it OR use a true Blind filter you can and will blow the steam pump.

    Note there is a fix for this... But it is a work around; that being said... I did it to mine and happy.

    Some time in teh next week I hope to have a post up as to mods to the EM69xx series; that will enhance reliability for both units but more so for the 6910 - Steam and group..

    AM, looking forward to your posts.. also perhaps some pros/cons of re-programming an EM6910 (steam and brew variables, etc)

    A simple back flush seems to have fixed the problem, so all good.

    Not fixed by solved the intimidate cause... Grinds in the lines.


    If ya not careful..... Dead pump system.

    SB are now identifying the issue of a FAILED Coil Vs User generated... Art some stage they will fix or just put back on the user..

    Idiocracy in the wings...

    Re: em6910 steam issues

    OK, so what do you suggest as a longer term solution? How do I clean / avoid "grinds in the line"?

    Search and follow the directions that have been posted time and time again.

    1: Do not OVERdose... 5 cent test

    2: Regular maintenance and Depending upon usage:

    A: - Short manual run or two with teh rubber blind at the end of the day ??.

    B: - Correct chemical back flush and cleaning of the shower screen etc every 3 weeks ????

    C. - Good water - Filtered is not filtered

    3: Purge ya steam b4 and after using

    4: After ya dump ya puck... place group in lightly - hit manual and wiggle a bit [smiley=2vrolijk_08.gif]

    5: Do not over lock or force the group in = OVERDOSE

    6: Keep ya group seal in good condition.

    And the list can go on.. Do some searching and spend the time to read...

    Re: em6910 steam issues

    Excellent tips - thanks! so far I have only been doing about half of what you suggest.....

    1. I am not sure what the 5c test is, but I will do a bit of searching around.
    2.
    a. Short manual run sounds like a good idea.
    b. back flush regularly. yep
    c. water could be better for sure
    3. yep
    4. I normally run manual without group in + rinse the group, but i will try the wiggle!
    5. yep
    6. yep

    Looks like is was indeed a temporary fix, as the blockage has returned. :(

    Sounds like you have got grinds in the system...

    That means a pull down and clean out... Try SB for a Warranty Pump job ??


    Where are you located ?

    Re: em6910 steam issues

    sounds like it....

    Im in Sydney - closest service centre is Ashfield.

    After talking to them last week, it sounds like they will only cover it if its the pump and nothing but the pump. If its blocked they will likely charge me.

    I could attempt pull down + clean out - I am reasonably handy with stuff like that + see quite a few posts on how to do it...

    Does the pump sound likes it working ... If not working then the switch OR the coil.

    Being handy BUT working around and with 240V parts is not legal NOR safe !!!


    Assumptions kill people.

    Scale and or grinds in teh system..

    Thus would need to be stripped / fully cleaned with a REAL de-scaler / Solenoids pulled down and cleaned and then it may work..


    I am looking for DEAD units; see my other post WTB ;)

    True..

    If thats your intent... Do your research, as Matrix ? etc and others have many posts as to Last ditched attempt to clean steam wand etc etc and plenty of pics.

    Some have also admitted to getting into trouble...



    wouldnt be the first time i have attempted such an activity

    Could also be a Last...


    STAY SAFE... DISCONNECT .... Do the Work and then get some one else to check.

    If you ever fully choke an EM6910 and keep pushing it OR use a true Blind filter you can and will blow the steam pump.

    Im wondering how fully choking the brew pump effects the steam pump??? :-? :-? :-? :-? :-?

    They are 2 seperate pumps...

    SO.... *Ever think they might be connected ? *And if so how and what components may be in between.. *Does every one truly understand how a vib pump works and or the configuration that the manufacturer might use.

    Ever worked with SSRs... I have seen then wired almost back-to front and linked input to out put *:o :o :o Does not make sense... *But some one much smarter than me figured out a neat way of using it for a smart outcome...

    Programming and un documented features... Allows some to do things the average coder would never consider.

    Assumptions is what gets people into trouble...

    How long have I been pulling EM6910 and others system apart.. *Do I know them 100% back to front NO.. * I learn every day.

    Can I explain in 5 min ... NO... It involves valves, OP systems and a FAULT condition to develop and presto the guts of ya vibe pump get coffee fines in it and stuff it. *YES the SB repair agent can see this.

    Should it happen NO... But if you do things incorrectly; then no manufacturer can cover off on PEBFAG.

    My car has good breaks... *But if speeding in wet wet weather and come to a T junction and only apply the breaks 10M out... Will my car stop in time - NO. *Manufacturer or *Driver ?

    Yea.. Today the thought is Manufacturer. Idoriacy *;)

    Enjoy the coffee road.. It can get bumpy...

    PS. Dont take it personal. Some days are better than others for me.. Depends on Coffee and Meds *;D :o *8-)

    See here http://coffeesnobs.com.au/YaBB.pl?num=1270540936/4#4

    And not the full story and all the minute detail is not covered.

    But many people assume and you know what that does.

    Any one ever fully studied the flow diag and asked what if this failed and or this got stuck ?

    The hard one is "What will happen when a member of the public uses it " - And guess what NO one can answer that other than *"they will stuff it" nothing is ever user/ 1d10t proof.
