    Hi guys, ive got a problem so if anyone can help out it would be appreciated.
    I was foolishly making a delish coffee during a big storm and whilst steaming the milk i got zapped. However my machine continued to work fine. Then another storm hit the next week and damaged a couple of lights etc. My machine suddenly acted funny that morning. Now my Sunbeam EM6910 doesnt do what it used to. It makes a strange sound when i pump the water through it. It also doesnt come out with as much force or pressure, heaps of water still comes but sort of dribbles out. I cant get any crema whatsoever. The pressure also takes ages to build up - about 5+ seconds to get any then shoots up quickly and crappy dark watery shot comes out. Any help would be so helpful. thanks

        Hello
        Should be able to push through water with a syringe from the bottom of the steamer to the top where I should see squirt out. If it is blocked how can I get vinegar into it if it's blocked. I can push a drill bit into the bottom hole of the boiler to a depth of 1cm. The pump works fine, the copper tube that leads to the steam tube is clear.

          Hi JasonC... Don't force the drill bit - any kind of efficiency would have the tube in a spiral inside the thermoblock.You don't want to scrape metal into the line.

          I just do the cleaning cycle but spend maybe 5-10 minutes running the cleaner through the steam wand. First time I did it I got a cough and splutter and suddenly had good steam. At first I used Cino Cleano (from local roaster) but more recently I have white vinegar.

          If the thermoblock is blocked, try using a normal coffee machine cleaner through the steam system but let it run till it comes clean. If you have it apart, try putting the cleaner in the top and wait and see if it works through.

            I am having blockage problems with my em 6900 can anyone give me a hint how I lift the top of the machine.........loosened all the required screws........top loose............but cannot remove it as steam knob shaft and the hot water shaft are wider than the top. Can't get at the steam and hot water valve without being able to get the top of the machine off..................looks like a real catch22 situation.

            Also does anyone know if the main control board on an em6900 is an exact replacement for the em6910 board??

              Newbidrinker, there is a small screw in the centre of each shaft, take out the screw and pull the shaft off.

                Thanks actually worked it out for myself just after I posted.
                Now can anyone tell me how do I strip off the outer shell (front panel and side walls) to get at the internals of this thing

                  Front panel, as in behind the group head and down to the drip tray? Don't need to remove that for any sort of work.
                  Top of the machine will lift off, sometimes have to give it a firm tap at the back to release some metal tabs that go into recesses in the side panels. Be careful of lifting it past the microswitches for the steam and hot water, you can break them if you're not careful.
                  Side panels are secured by 2 screws in the bottom of each. Remove them and they'll lift off.

                      What a good find, you will be well pleased.

                      Notice my mistake above, calling it a blocked boiler, instead of a thermoblock

                        After much frustration with scale in the steam wand, I did what davek near the top of this thread suggested, using a vinegar solution.

                        Great steam ever since

                          Where On Tgis Thing Is The Serial Number? Im Getting Leaking Over The Top During Pour, No Matter How Firm I Lock It Into Place. Its Only 2 Months Old. I Have Tried varying Levels Of Coffee And Tamp.

                            First thing to try is to dose less. I dose to about 4mm below the rim, maybe even 5mm. That puts about 15g - 16g of coffee in the basket and gives excellent results.

                            Next thing to ask is, have you removed the showerscreen/blue seal to clean? I had an unstoppable leak at one early stage and found I had somehow messed up putting the seal back in so it wasn't tight to the group head.

                            When you say 'all over' do you mean all around the top or is it coming mainly from one place? If it is all over you should take off the showerscreen and blue seal (use back end of a teaspoon to lever out the seal - you don't want anything sharp gouging it) clean them and make sure they go back in properly. Note there are 2 screens, and both 'slot' into grooves in the blue seal, the smaller one is the inner (closest to machine) one and the larger one is the one you see when you look up at the group head.

                              A friend just gave me her old EM 6910. It has never been cleaned as far as I can tell as the cleaning disc was still taped inside the back door.

                              I cleaned the externals and I am getting some tablets and descaler to clean the rest today. Two things I noticed when making a coffee.

                              The pressure gauge isn't working at all.
                              The steam is very weak it heats the milk but I am not getting the nice whirlpool needed to create good milk
                              The shot has no crema granted I am still saving up to buy a grinder so these are preground beans and not too fresh but there isn't even a hint of crema.

                              Hubby will take a look at it tonight as he is quite handy (takes apart planes for a living I hope this is a little more simple)

                              any hints on what to look for?

                                Hi Pennyc

                                Just give it a proper cleanup and see how it goes. 6910 is a real espresso machine: pressure gauge is unlikely to do much movement with supermarket coffee "universal grind" anyway as it is far too coarse. The watery coffee will just flood through giving almost no resistance.

                                Speaking of the pressure gauge, it may be blocked. Tell your hubbie to be very, very careful as it is very easy to break the thin pipe which feeds into the pressure gauge.

                                You need a No2 philips to remove the showerscreens: 6910 has two of them and coffee tends to build up between them. Checking and cleaning the seal is also a good idea.

                                Other than that, check the portafilter handle: if the plastic part under the basket is in place, it is essential to remove it (you will not believe the junk underneath it).

                                Have fun watching him toil...
