  • 6910 - is this the end ?

    Hi all, hoping AM is at hand. My 6910 has developed a steam issue. The pump is pulsing with it usual frequency but it goes from been very audilbe to nearly silent in a random cycle. The steam output is pissweak and very wet, despite been on factory settings. No matter what I do it just screams like a banshee when attempting to texture milk ( with zero success) and Im not sure which way to turn. This machine was purchesed in December 09 ( replaced a faulty 1 month old unit) and gets treated ( some would say) way too kindly. Im at a loose end - help.

    Cheers.

    Sounds like it could have a minor blockage... Maybe..

    But if under a year old... I would hit Sunbeam up as a warranty...

    The steam pump does have a 5 year warranty and with your attention to detail etc... Sounds like a real issue has developed.

    You may wish to try Hottest steam setting and then go from WETTEST to DRIEST ( ) settings and see if that moves any thing.

    Then reset and go back to default. After that... SUNBEAM..

      Thanks AM. I was really hoping to avoid a 5 week turn around with sunbeam. The machine has an extended 5 year warranty anyway. But I reckon Id spend enough on take away coffeee over the repair period to just buy a new one ( or upgrade, not that I want to). Im ready tro break out the tools and go nuts. I have just about every tool made and I aint afraid to use them. ;D. It is most strange though, when the pump go quiet, the steam more or less stops, then the pump gets loud ( normal) again and the steam ( watery ) resumes but only till the pump goes quiet again ( 2 - 5 secs ). If it doesnt resolve itself do you feel like having a tinker, or are you too busy ?

        I just did some quick figures. This machine makes 55 milk based coffees a week. Assuming sunbeam would take 4 weeks to turn it around and allowing $ 3.50 per cup, its going to cost me $ 770.00 best case scenario to get them to fix it. Maybe I should take it back to Harvey Norman and just sit there until they give me a new one - ?

          55 milk based drinks per week is going to cost you around 10K per year if purchased at your local cafe. Forget the Sunbeam and go nuts with a pointy end HX. You are already ahead and with that volume of drinks, you are going to need a robust machine. Then keep the Sunbeam for a weekender or sell it after Warranty repair to soften the initial outlay of the new purchase. Most Snobs who make more than 2 coffees a day immagine they are entitled to a setup at home that could easily service a small cafe. You... Mr 55/week by comparison should have tree chipper for a grinder and a 6 group La Marzocca. ;D

              What a weird coincidence.......

              Mine started doing this this morning. Exactly the same pattern as derrilex. :-?

              Has done it for two coffees so far. Might need to have a few more and see what happens.....

                1: What happened at the wettest and dryest settings ?

                2: Sounds 100% like a pump fail problem = Warranty

                3: While getting a repair... Look at a HX :-)

                4: After repair - Sell and recoup some $


                I could look, but all I could do is change the settings and then swap out the pump...  Which I would have to buy    Which should be covered...

                Check to see the colour of the pump.. Blue / RED / Orange ?

                If red it is a good pump.  If Blue or Orange... Then China and they are having a issue with reliability on some batches....

                WARRANTY

                  No luck with the wet / dry alternating. Even had to resort to a short black this morning. Is there anyway of seeing the pump without dismantling ? Sunbeamwould probably crack the poos if it were tampered with. I saw on a post elsewhere that the pump is about $ 30, if so I would gladly give the repair to you rather than been without a machine for weeks and weeks. + labour of course.

                  Credit where credit is due for the sunbeam, it gets a floggin. The details are

                  Monday - Friday

                  wake up- 2 milk based, me + wife ( 1 each.)
                  8.30 1 milk based - me
                  lunch 1 milk based - me total 7 per day
                  3.30 1 milk based - me = 35 per week
                  6 .00 pm 2 milk based - me + (wife 1 each)

                  Saturday / Sunday
                  wake up 2 milk based - me + wife
                  straight after 2 milk based - as above
                  11 - 12 2 milk based - as above total 10 per day
                  3.30 2 milk based - as above = 20 every weekend
                  6.00 2 milk based - as above

                  grand total 55 per week
                  minimum, does not include friends dropping over for a brew.

                  Funny though, I dont consider this excessive because they are spread out during the day. I dont want a machine that I have to warm up for an hour, plumb in or modify. I just want my coffee. 6910 gets warmed up for 20 - 30 mins each time or left on if the coffees are half hour apart like in the mornings. I definitely dont want a machine with a pissy little boiler , after the sunbeam instant milk stretching while extracting I could never go back.

                    Re: 6910 - is this the end ?

                    The on/off of the pump is a bit random on mine, not a set pattern...

                    Im starting to wonder if a blockage is the cause, with a build up of too much pressure seeing the pump stop intermittently.

                    I did a descale Monday night and now this today......

                    I think I might try another descale and see if it fixes the problem.

                    Oh, and I have been getting the occasional strange buzzing noise when using the shot/water pump....

                    PCB on the way out possibly?

                    I might also use this as the excuse for an upgrade......

                      Service agent seeing lots of same issue. Change in water in Brisbane. West is worse of all and all makes scaling up. Some are realy excessive.

                      They use a special heavy cleaner and a manual soak and two way flush.

                      Tryst this helps.

                        If you ran the descaling solution through the steam system this may have caused your problem - Sunbeam caution against doing this in the manual.

                        @derrilex - with your usage the Sunbeam already owes you nothing so +1 to saving for an HX.

                        Mind you, I reckon my Sunbeam has paid for itself plus a couple of grand - yet somehow I still get the look when I talk about spending half that on a grinder! ;D

                          Running Bombora Clean Machine Triple Action, not Sunbeam tablets so it is safe.

                          Never had this problem in the past.

                            So whatchya reckon AM, are you up for some surgery ? Im on the inner west, ( graceville) so Im pretty close to the water treatment plant as the crow flies about ( 15 km) . We have noticed a different taste in the tap water.

                            Is it easy enough to remove the steam thermoblock once the covers are off ? I assume this how the soaking is done ( in a bath of solution ) ?

                              @derrilex

                              I am pretty sure I have fixed it.

                              Been descaling the steam wand again for the past 3 and a half hours...

                              Bombora triple action, running it through the steam arm only, every 15 minutes for around 2 minutes. Gone through nearly 700ml of solution.

                              Started with the steam tip off, until I got consistent pump action, now with the steam tip back on.

                              Some interesting coloured cr#p came out too.

                              Steam now shuts down the moment I close it too, showing there was obviously a build up somewhere.

                              I dont think it is the pump mate, maybe like mine just needs a really good clean.

                              Good luck

                              Still thinking about upgrading anyway.... ;D
