    Can someone take a look at my video. My em6910 is taking time to build up pressure and does not reach a good pressure while pouring (blocked ??). I have descaled it a few months ago (and regularly before that). I have replaced the group handle seal, water filter a few months ago.
    Any ideas, I really don't want to go out and get yet another machine if iI don't have to.

      After trying some other store bought coffee as an interim till after christmas, and giving the machine another clean, I think it was the crap beans.

      AMD, thanks for the quick response.

        Spoco2' did you finish up replacing the pump? I have just gone the same route as you, cleaned the pump components, but still the same, steam but not enough. I will order a pump Monday. I think the problem is wear on the rubber (perhaps neoprene) seal adjacent to the nylon washer. As it wears the contact surface becomes larger and causes the piston to bind. A new o ring would sort it but I can't find one so a pump it is.

          Hi,

          I did indeed install the new pump and it's been working flawlessly since. Very happy with it as a machine.

            My 6910 steams just fine but it takes a second (as in 'one-onethousand') to turn on then about 4 - 5 seconds to get rid of the water and start producing steam. I'm interested in your comments Spoco2 that you had a delay in steam - as in, do I have a [problem coming up or does your new set up have similar performance to mine?

            Excellent thread, BTW, good detail and well put together for anyone wanting to investigate their ineternals... well, their coffee machine internals...

            Oh... and if this was a prize from Gloria Jeans, what was 2nd prize... TWO non-functional machines? Click image for larger version

              My one used to take many seconds, and then minutes, and then not at all... if you listened closely you could hear a quiet buzz buzz buzz as it was giving power to the pump, but the pieces just weren't moving back and forth.

              It now starts properly making pumping noises as soon as it's switched on, it's about a second before anything comes out, and then will spit out water for a little bit (couple of seconds I guess) before blowing steady steam. I think that's pretty standard, you'll always have a little delay as the pump pulls water through itself.

                Thanks, that's what I figured but just wanted to check. Sounds like mine is just fine.

                  Hi Guys
                  Just an update.........
                  After having enough frustration over my machine deciding when it would pump steam I finally took it to our local service agent. He charged me $50 to have a look and said it was the steam pump and also needed to replace an O ring. One quick call to Sunbeam and all was well..... got my pump replaced and all it ended up costing me was $68.........
                  Not bad to say my machine is now 4 years old! Very happy bunny So glad Sunbeam offers the 5 year warranty on pumps.
                  We make at least 2 coffees a day everyday so this machine has more than paid for itself, makes great coffee to by the way as long as I fill the group head well, I use more coffee but small price to pay for having coffee you enjoy.
                  Will just have to read up on posts regarding if steam pump goes again whether to fix it as it will be out of warranty by then or upgrade to the new version.
                  This machine was only going to be a step to see if we would use it enough and could justify spending over $2000 on the next one but so happy most prob will stick to this brand for good value for money

                    hi, which store did you go to fix the steam pump?

                      Just a reminder which screws go where

                      [ATTACH=CONFIG]1371[/ATTACH]
                      The view from the side, showing the pump at the bottom. You'll need to unscrew the metal pipe that leads into the top, take off the plastic pipe leading into the top also. Then you can get the pipe off the bottom (I find a flat head screwdriver works well to slide them off) and pop the pump out of the bottom bracket, then lever it down and out of the top bit.

                      [ATTACH=CONFIG]1372[/ATTACH]
                      You'll be left with this thing, undo those two screws holding the black plastic portion inside the blue part.

                      [ATTACH=CONFIG]1373[/ATTACH]
                      The 'pump' bit. You can see in the middle a little notch. If you hold it at both ends and twist it you can separate the two halves

                      [ATTACH=CONFIG]1374[/ATTACH]
                      Then all this stuff falls out.

                      I'm pretty sure the problem lays in a little black grommet behind that white disc (sorry, didn't get a photo). It seems to hold the brass coloured bit to the aluminium coloured bit too tightly, and they're supposed to move back and forth in relation to each other. If I take out that grommet the pump seems to move no problems when put back and powered, but no water pumps (I guess as the seal is lost), so you need the grommet, but just need to to still allow the inner metal piece to slide in and out ok.

                      I put all the pieces in some cafetto to clean them, I tried giving the inner rod a good sand to try to make it ever so slightly thinner... and the pump does work, but still will 'stick' for a second or so before kicking into life when you first turn it on.

                      Maybe someone trying this can work out the real root cause and work out a better fix, because I'd hate to have to spend over $60 on a new pump when this one really seems fine except for that bit of 'sticking'.
                      Thanks spoco2 - I just successfully replaced the steam pump in my machine - couldn't have done it without your photos and post! Nice work

                        Great to hear

                        My machine continues to work perfectly since that repair. It worked out to be a good investment

                          Hi,
                          I have also had the experience of the steam pump failing on my EM6910.
                          My machine is about 3.5 years old. The steam wand played up about a year ago and seemed to improve after a descale but maybe that had nothing to do with it
                          Last week the steam stopped completely, although I could hear the boiler and the switch working .
                          I found your detailed reports on the repair by accident and as a result will go ahead and try repairing it myself.
                          I have ordered the part, after being knocked back by Sunbeam for a warranty claim. ( The guarantee is 5 years for steam pumps but they wouldn't come to the party because I had opened up the machine ).
                          I will report back on how it goes.

                              That's a shame that SB wouldn't honour the warranty. Yeah, please do report back on how you went. The more successful repair stories we have, really does add to the wealth of information. Hope it works out for you!

                                Maybe, would be interesting to know how many there are out there compared with other brands.

                                And as for our 6910, some 7000 approx coffee later, after a new thermoblock, and a thermal cut out fuse (just recently) it can not be all bad.
                                And it does make good coffee, and quite quickly.
