    Re: EM6910 not setting itself

    Thanks for waiting gentlemen

    Here are more tests i did.

    You talked about the situation being intermittent AM, i turned the thing on to see if it was heating up. Turned out it went back to normal, ie. Power light flashed, then all lights on, not blinking. Brew block felt damn hot. Thermoblock felt damn hot.
    If this situation is an intermittent problem, it may be all is well now, but may and will re-surface in the near future.

    When i rang service at Five Senses when it reared its ugly head again, he said its an intermittent problem. Cant fix it if unable to trace blame of source if its working well.

    As promised, heres more pics with the multimeter, and im sure you will comment and advice AM. Thanks again.

    Here is a list of results from resistance reading on the DMM logger:

    Group element 47.30 ohm
    Steam element 51.00ohm
    Solenoid test 2.236 kohm
    Red box thing (pump for brew??) .100ohm
    Brew thermistor 87kohm
    Steam thermistor 91.00kohm

    Pics as follows:

      Just want to be sure, the black box is the solenoid?

      Not sure what the red box is, is it part of the pump for the brew dept?

      And the blue box below closer to steam thermoblock, is it to do with the steam function?

        Errr   oooooo   Could we have the travel sick bag up to QLD please ASAP ;D


        Interesting Shorts and !!!!!!!

        Lets hope this was not all done in the out house  

        5 Senses are correct.  With out a hard fault you could replace every thing and still miss it.

        When it next failes again... Measure ASAP and see what changes..

        My gut feel is that it is the Thermostat....

        Main Group is a 110C and teh Steam is 200C. If these happen to go open and do not reset for some reason. And then after sitting and getting cool or a bit of a knock it resets. That would explain it... They also have an interesting rivet construction and that could also be part of the problem...

        I will try to send Pics  ( No shorts or belly)  in the next day or two.   I have an 18th on tonight and then allowed to visit a special correctional centre. Thus you get a back seat.

          Hee hee. This was all done with machine off and the machine faulty prior to tests done. Each wire was unplugged then tested for resistance then re-plugged, one at a time.

          Then when i turned machine on just for the heck of it, i noticed both group and steam was hot.

          All tests done indoors. Just so happens it is raining buckets outside now

          BTW. sexy shots of belly and shorts belong to stepfather. He is a qualified electrician working for BHP Billiton.

          Hes just not familiar with the innards of a coffee machine but he did recognize electrical components.

          As for me, i have a clause to my contract that says i will not expose more than my hands and arms until available in full for the Coffeesnobs Corner of Beanscene Magazine ;D

            ROFLMAO... YEA right... Sound great !!!!! Cheque is in teh Mail ???


            Ok... With what you said, and am even more inclined to think THERMOSTAT...

            Confirm if it is teh Group or Steam and I have one or two sitting around...

            Thus I can send you a replacement to get you working and to confirm - Send Snail mail addy ASAP via PM...

            PS. As to CS corner... Until the fees and STAR status, go up a bit, I am continuing to ignore the begging and pleas ;D

              Re: EM6910 not setting itself

              Havent taken my machine in yet - my husband will need to drop it off after work on Monday hopefully. But I was thinking maybe my fault happened when I did the settings to increase the temperature of the water, steam, wetness. I put them all on the highest settings. Im thinking maybe it stuffed up the temperature thing?

              My husband is thinking to change machines now. Its probably going to cost another at least $150 and we just spent $200 getting the collar and seal fixed. Quite depressing!

                Not ya fault...

                What is your location ?

                If it is teh thermostat, then a $18 part and the issue of changing to the higest does suggest that if the thermostat was on the border line. Then this could do it...

                  Gee. Thanks a million AM. Ill take you up on the offer.

                  Will let you know when it dies again which thermostat is responsible.

                  Is the thermistor the same as a thermostat? Where is the thermostat located if its not the thermistor?


                  Turando, I hear your pain. When it comes to the stage when it costs a third or more of the value of the machine to fix, you have to wonder if its all worth it.

                  To me, i can get attached to something when it has been with me for some time, temperemental or not.

                  Bottom line though, you want to enjoy making coffee, not waste time toying with it or fixing it.

                  AM and I, we go through these processes of elimination and detective work in order to help the next person with their machine if they happen to have a problem with it and is willing to have a go at fixing it.

                  When i get to the bottom of it eventually, theres a sense of achievement, and im sure it gives AM a good feeling when he shares his knowledge for the good of others.

                    Re: EM6910 not setting itself

                    Gary, the $95 was the part price for the thermoblock. Replaced mine and all seemed OK, but then I just might have got lucky, not knowing what the real problem was. It might have been loose wiring, and when I connected everything up it worked. I wasnt going to take everything apart again just to see if the old thermoblock is alright. What I can not come to terms with ii the cost of consumer replaceable parts {eg. anti-calc cartridge $30+. group-head seal $30+, filter basket $22+ and so on} as against what appear to be more intricate non serviceable parts (eg. PCB&wiring $69, Steam thermobloccl $95, Collar $58 etc.).

                      Re: EM6910 not setting itself

                      AM Im in Melbourne. Is the thermostat hard to change? I wouldnt mind doing it if it doesnt involve a huge amount of disassembling.

                        Yea, the pricing appears all wrong in the first instance...

                        However if like many in the white good area... Consumables are expected to be bought and used by users and teh Hardware only by Service agents.

                        Thus one could assume that if hardware was cheep enough then Service and Repairs would also be cheep - SHOULD they ever be needed. However we all know it does not work that way.

                        The steam Thermostat is easy to get at and to change... The Main group Thermostat is ON top of teh head and thus requires the machine to have teh lid off.

                        The thermistor is the temp sensor that is used to feedback to the brain.

                        An electrician should always be involved or check the unit as to electrical safety before attempting to power teh system up.

                          As per another post....

                          Agents have seen blocked Steam Blocks BUT elements failed = VERY RARE.

                          The symptom described "not setting itself" ALL lights flashing is due to teh system thinking that either teh Group OR Steam block is not to temp...

                          The most common fault in older units is with those Thermostats... Yep that little can etc with the two tabs. Also if intermittent, then even more likely to be the thermostat.

                          Get ya local electrician to replace !!!!! Group is 110C and Steam is 200C

                          DO not remove teh cover or do any work on your machine if your not Qualified.

                          Gary from Gala is OK as he has a Rel with a Special body type ;D (Photoshop is not a core app).

                          Take care all
