    Re: EM6910 not setting itself

    My machine just got the same problem - light flashing green - the machine is hot. Did anyone find out what the actual problem was? I just spent $200 at the sunbeam repairer 2 weeks ago getting the collar fixed so am not looking forward to fixing this now.

      Re: EM6910 not setting itself

      Got my machine back at last on the 24th.

      $71.00 later and the problem with my machine was loose wiring.
      Am a lucky man it wasnt anything serious.

      As AM was listing possible causes, mine was more like quote"= Either Thermistor disconnected from PCB, reconnect" unquote.

      For you guys hopefully its a simple fix.

      I was told worse case scenario would be to replace the steam thermoblock which would come to $180-190 all up.

      Turando and freaky namuh, where are you located?
      I got mine fixed at Five Senses Coffee in Rockingham near Perth,WA.
      They did a check up on the rest of the machine as well.

      My machine is more than 3 years old. Other than that problem cheaply fixed, have had nothing else happened, touch wood.  :-X

        Sorry AM for not getting back with final outcome. Replaced steam thermoblock for $95(supplied from service agent). Everything seams OK.

          Well done and at a good $.

          Seems that a few are having some strange problems and the fix seems to be every thing from loose wiring ? to the Steam block and some with very different pricing.

          I guess this just helps in demonstrating the different levels of service support that is out there.

          AM.

            Looks delicious Gary at G - I am excited about getting into roasting, just gotta wait for my bank balance to recover before I buy some roasting equipment!

              Thanks Gary S.

              Roasting your own adds another dimension to the whole coffee enjoyment and experience.

              Theres plenty of CSers right thru this country who will be willing to help you along the way.

              Maybe cu on Sunday, not Saturday. Dates changed.

                Re: EM6910 not setting itself

                $95 all up cost including the thermoblock and labour?  

                Youve done well there. You must have done that Ikea lady who looked quietly surprised at the bill and made a hasty rush back to the car.
                "Start the car, staaaart the carr...."

                Sorry AM, i cant donate my 6910 to you just yet. The girl has quite a bit left in her yet  , maybe another 3 years....

                So the list of things that may be causes of the OP,

                Electrical: Loose wiring(in my case)
                  PCB
                  Thermistor faulty
                  Blown element in block
                Mechanical: Anything mechanical that may directly/indirectly affect the electrics?? Hence my question.

                God shots to those with good news about their repairs  

                For those who are pulling their hair, spill your guts here. Well listen to you.

                  Re: EM6910 not setting itself

                  Gary S, if you have $52 - the cheapest way to start is:

                  1 - get onto beanbay and buy a starter pack $32
                  1 - go down to Kmart and buy a popper $20
                  2 - take it home, put in some green beans and start roasting

                  Youll never look back ;D

                      Dropped machine off last Thursday 6th Jan. Have not heard from them despite calling twice. They said they will get in contact with me but so far have not.
                      Not a good omen from a reputable company.

                      Im sure someone out there has gone through the same situation.

                      Have been very polite in my calls to them as being impatient is not good for a pleasant outcome.

                      To be continued....Sad
                      Date today:29th January 2011,

                      Well, i knew in my gut feeling that this problem does not go away.
                      This time, the machine indicated ready, i went to water garden to give the machine time to warm up....came back in after 10 minutes and found the Power button light flashing again !! "oh, here we go again".
                      This time i managed to get Ashley on the phone surprisingly rather than the friendly lady taking my details and having to wait for another day before i have to ring again.
                      From what i gather from my conversation, its an intermittent problem.
                      He mentioned he fixed the problem by re-connecting a loose wire, then did a test on the machine to make sure everything else was working fine.
                      I asked him how he did it and why the problem has re-surfaced again.
                      Said a multimeter was used to check, and visibly looked at other components, and the reason why the problem came back is due to it being intermittent.

                      Had a friend a long time ago with a similar problem with his car. Electrical intermittent problem which the mechanics couldnt trace.

                      I write this with my blood pressure back to normal and my use of language toned right down in a gentlemanly manner.

                      I feel this is something that will re-surface again when the problem is fixed again....or am i wrong?

                      At this stage, i dont mind opening the thing up and having a go at testing it with the DMM logger, but i dont know where to start.

                      Just feel something not quite right when someone tells you a thermoblock is being ordered and on the way, and then being told it was a loose wire.

                      Now i know that cheap fix is too good to be true.

                      Any advice or your experiences are appreciated here. Thank you.

                        Got a technique for frothing milk on the EM6910 in "Milk, Froth and Bubbles"which i hope to share with you and others in the near future using photos which is a important factor for artwork Yash.

                        Hi Yash,

                        The machine has developed the same re-setting problem...again.
                        Was planning on doing a photo tutorial on steaming milk on the EM6910 to assist anyone doing latte art on their EM6910, but will have to wait a little, or a lot longer.

                        To be continued...

                          Re: EM6910 not setting itself

                          Have opened it up, tested the resistance using the Coffeesnobs DMM logger (knew it would come in handy somewhere else).

                          Steam thermoblock terminal to heat element: 51.00 ohm

                          Brew thermoblock terminal to heat element: 47.30 ohm

                          Solenoid: 2.236 Kilo ohm

                          A bit worried about the solenoid, sounds a bit high.
                          Im not electrically minded, so hopefully someone else can comment on these results.
                          Can post pics if required.

                            Post pics and I will do some testing and report back.

                            Check the Steam and BREW block temp thermistor !  At room temp they should be about  85K ohm

                            If I remember correctly you can do a Single measurement and it will take into account the Heating element and the thermal fuse etc so that your sure there is a  true cct and you not confusing your self.  

                            This is between one side of the Solenoid and from either of the two wires that are soldered onto the SUB board.  One wire is steam and the other is Head.

                            I got 47 ohm for steam and 54 ohm for Group... This minor differenced is not an issue.

                            Thus it could be;

                            A: The board is stuffed - The bigwarehouse have them for $70

                            B: Thermistor is playing up and not seeing that it has reached temp?

                            C: The THEMOSTAT is playing up and not letting it get to the right temp but is measuring OK at  room temp when when you do the test I described.  From the same place ss above $18

                            So the trick is to confirm what is getting hot and what is not and then you can focus on the right path.

                            Much of all this can be done with the unit disconnected  and removed from any Electrical power supply OR without having to pull electrical connections apart etc.


                            If and When it comes down to a live test: That is for an Electrician and no one else.....

                              Can I add that it could still be the thermoblock as the heating element could be cracked/broken internally in such a way that when cool it measures OK but as the thermoblock expands when heating up it goes open circuit.

                              It could also be the same type of fault in the crimped connectors on the ends of the wires attaching to the thermoblock.

                              Either of these could well cause an intermittent fault as the wires/elements would shift ever so slightly every use due to thermal expansion/contraction and vibration (From the pump).

                                Heating elements usually fail in a much more hard core manner... As to the terminals... Always a possibility but rest assured if intermittent it is more likely to be in teh board rather than the element or connectors.

                                However only a critical review and test will determine the real cause. In teh mean time I have seen many get told rather interesting stories that often astound me.. 30 years in teh Electronics field... Some times it is a case of Generalisation by a repair person and other times it is a big bow they were pulling...

                                Still waiting for Gary @ G to get back to us...
