  • Shower screens for EM6910

    My Sunbeam EM6910 is about 18 months old now and going strong. I have been very happy with it, the only issue is the group head needs replacing as it is worn (3yr warranty should cover that).

    I have found this machine performs best when kept clean, I have made 2-3 cups per day and flush the group head about every four-six weeks. I notice that when pours become less consistent and pressure increases its time to clean. Just recently I noticed when cleaning the shower screens that they are poorly machined and a lot of the holes are not punched thru properly and have burrs (particularily the inner or top screen). Some of th burred holes tend to block and after a clean they still were not clear.

    My question is:
    Are better quality/machined screens available? Maybe this may give a better pour and stay cleaner. I have Synesso baskets for the group handle and the holes are perfect. See 2 attached photos of the inner and outer screens.

    Short answer NO..

    You could go along to a Service agent and see if they have any in stock and then pick the best one... Note: Not sure they are even held as a standard on the shelf part.

    Depending on the T&C the worn Group collar may or may not be fully covered if at all.  Assumptions as to what is and is not Vs the extended warranty can be a trap for some. As it is not a SB warranty, if I am correct.

    Let us know how you go...

      good luck with the warinty thing as the problem is "normal wear and tear" not a manafacturing fault etc.

        the majority of Extended warranties only cover things breaking (manufacture faults)

        NOT user errors
        Not wear and tear
        not abuse

        and definately not
        my machine doesnt make crema anymore
        or my gauge doesnt work
        (because i havent been chemically backflushing the group regurarly)

        or my water flow is slow
        (because i live in Syd or Canberra i dont need to descale my machine)


        Thermoblocks need descaling more often than boilers

        [highlight]Sunbeam EM6900 /10 need more coffee chemical cleaning than a commercial or semi commercial machine [/highlight]otherwise it blocks up and the gauge wont work, and you cant backflush anymore

        if you dont want to clean it, dont buy a sunbeam em6900/10. it will block

          Am I right though in thinking that collar wear is unrelated to cleaning or lack thereof? AFAICT this could be caused by overdosing, failing to replace GH seal regularly, heavy-handedness (locking the PF too far) and possibly just everyday wear and tear.

          But in the absence of user error, I wouldnt have thought wear and tear would be an acceptable response after 18 months of non-commercial use - taking into account the cost of the machine, intended purpose and cost of replacing the collar. It could be argued that its caused by a design fault, and thus covered by warranty - either manufacturers, extended/third party or statutory.

            YES and NO....

            Excessive collar wear is and can be caused / impacted on but not limited to;  by overdosing, failing to replace GH seal regularly, heavy-handedness (locking the group handle too far) and poor cleaning or lack thereof?

            Coffee grinds etc will add to ware issues.. Be they trappen all around teh group collar or left on the PF and teh lugs... That is why may professionals spend time wiping and cleaning with their hand... Good seal and consistent lock... As well as good practice and not leaving stale grinds trapped in place...


            For those 6910 items that I have seen, that have been managed with some level of attention, the everyday wear and tear is not that bad.  2 to 3 years no problems....

            The issue of Poor manufacturing and critical faults Vs user perception Vs  ware and tear will always be an issue for some...  See ya legal person and  work out the costs and what ya expect...

            A little bit like a gear box on a car...  What it is designed for Vs actual spects Vs how its abused Vs  maintained is not as simple as 2 + 2 = 4...

            If every one did teh same thing it would be simple...

            I for one, would suggest that it would take me about 15 min to 30 min to review an EM6910 and provide a report that would clearly indicate if the unit has been maintained correctly and or suffered use / actions that would contribute to the fault..

            So if ya chasing extended  warranty...  Do not bring it to me...  I would suggest that most experienced tecks can quickly work out if teh unit has been looked after or abused... Some times we get it wrong...  But not often...

            Its like people saying... No officer I was not speeding TRUST me....  I never Speed.   5 min later I hook my diag logger to teh ODBII connector to the cars computer and I can see the spped / all ya breaking and Accel forces and where they have exceeded safe limits etc etc etc Including throttle position and some speed info..  It is there in BLACK and WHITE..  Yet teh driver, will look ya in teh face and say...  

            NO... I never drive like that...  Or  

            NO... I would never hold the EM6910 with my L/H and arm locked while locking in with my R/H and popping my biceps  

            NO... I have never over filled and had water all over teh drying tray and dripping over the sides and over teh front buttons... No never

            No... I clean it every month..  No I have no tabs left.. Used the last one last week... Trust me..

            Yep, I am drunk, do not know ya name or number... But trust me I will call you in a week..

            Sorry... I am a hard core realist and like many on the front line get fed up with the stories told to divert from poor maintenance or some one wanting a new machine for nothing...  :P

              Even saying all that AM I found that the gh metal on the 6910 here at work (replaced under warranty) was extremely soft.

                YEP.. Soft aint the work for it

                The biggest issue is teh steeped lugs :-X :-X

                It often means that instead of a large surface area, you tend to get a the lip of the step that connects to teh group collar. That means the pressure is not distributed across a larger surface area and contributes to what I perceive as excessive force on teh collar... Even when used as per teh manual...

                I have ground off teh lip on my naked PF... But was sloppy when I did it and thus some grind marks on teh wall... However I did notice a marked inprovement.

                NOTE: The EM5900 no longer has stepped lugs.. But not the right size for teh EM6910.. Bugger.

                I can also state that by using a slight smear of "lanoseal" or another food grade wax type lube... Some sponsor do stock... And lightly coat the group collar / lugs.. It makes a great improvement...

                However, once again; these are after market mods and if the lugs were not stepped, many of the collar issues would not occur.

                I would also suggest that if the collar was made of a harder material the step on the pF lugs would show serious signs of wear and tear in a short time.. And or wear to the extent that the critical angle would no longer be a problem...

                As I see it... A cost cutting exercise when sourcing OEM parts to make the system.... Thus has led to a significant issue as to long term stability of teh collar..

                However, good maintenance and correct use is still a must be it an EM6910 or any other machine..

                  Really? While it seems obvious that the collar design is a bit lacking, and the metal used too soft for the application I would be utterly flabbergasted to learn that the collar metal is softer than coffee grinds!

                  I dont disagree that many of the faults reported with SB machines here and elsewhere are probably caused by lack of cleaning/maintenance and/or user abuse...

                    TG will understand... As he knows first hand how soft some of teh collar were...

                    If coffee was soft then why does it stuff up blades and after a while ALL coffee grinders need to have the HARDENED burrs replaced...

                    The grinds get in and take up space.. some may get crushed but it all means that somthing has to give...  Look at any commercial group handle and Group... The chrome is removed, the brass is showing through...  Lots of use and coffee grinds act as a grinding medium... As well as heat, they also impact on teh condition and assist in wear of teh seals etc..

                    The grinds are quite hard...  They do not have to be harder than metal to cause wear and tear... Just crunch a few in ya mouth and keep chewing.. Crunchy little buggers.  Do that consistently and see what happens to ya teeth.

                      Fair point - wouldnt this then indicate the use of a more durable metal for an application where friction and coffee grinds are an inevitable consequence of the intended use, though? The collar is not, after all, listed as a consumable part as grinder burrs are. And really, were talking about less than two years of non-commercial use - I havent heard of group collar wear problems on any other common domestic machines, some of which have been around for decades... so have to wonder what part poor design and material selection play versus user error.

                        I have and I have seen it... Usually when cheep er system get modded to run non pressurised... What usualy also happens is the teh PF and or lugs break / fracture..

                        Think about it... False pressure... Is generated in teh double floor of teh basket.. Thus NO NEED for heavy Groups or PF..

                        But when you convert to a single floor and then rely on the system / machine to develop and withstand the extra forces... SOMTHING has to give, and it will over time

                        Use a EM6910 with supermarket coffee and double floor filters and the collar will last for 5 years plus...

                        As the the material... TG, myself and others have done this to death.. Material of the collar and the shape of the PF lugs all play a part.

                          Dont know about that - pressure is pressure - it doesnt matter to the collar and lugs whether its created by a puck of fresh coffee or a metal disk with a small hole - they still have to hold the group handle in place. My guess would be that the additional wear on the collar when using nonpressurised baskets would be due to excessive updosing - after all, anyone who knows enough to use the unpressurised baskets will also know that you need to updose to get a good shot out of the Sunbeam... right?

                          As the the material... TG, myself and others have done this to death..  Material of the collar and the shape of the group handle lugs all play a part.
                          Well, thats my point. IMO poor design and choice of materials make a worn collar a potentially valid warranty claim - provided that the machine hasnt been abused.

                            Snort. I wonder how many 6910s would last for 5 years plus.

                              With appropriate maintenance, repair and replacement of worn out parts - no reason why they shouldnt. Just like any other machine.
