    Well so far so good. No really noticable improvement in steam, but no reduction either. Easier to get the vinegar taste out than the descaler solution so thats a plus. Just out of interest AM, what steam settings do you use or recommend ?

    Correction: The following settings are to a working machine and not when using a cleaning solution.


    Err... How long is a piece of string  

    Every machine is different... And then there is your method..

    The 6900 has ONE setting = default  - No option to change by the program  

    If my memory is correct...

    I did post it many moons ago  ;D  However ;

    1:  I had my group Head at + 2  Not the hottest...

    2: Steam temp at hottest (+10)  or at times + 5

    3: Wetness was an ongoing flip  / flop between Default and Dry  - Never found that driest made any changes that suited me or the milk.

    Trust this helps.


    [edit]When using a cleaning solution... Lowest temp setting and higest pump rate to give the wetest steam possible.

    Note: Early EM690 units are not programmable and MUST be done using a suitable cleaning solution and OUTSIDE to ensure suitable management of any fumes.[/edit]

        hmm, i would have assumed you would set the steam pump to pulse at maximum frequency, and set the temperature as low as possible, so the descaler would flush out.

          Your 100% right... Was still able to edit previous post. Sorry for any confusion.

          Slowest pump rate and the wettest setting..

          I answered out of context and was thinking more as to when the system was back in operation.

            No worries AM, I knew what you meant. I ( as per your instructions) made the steam wet and low temp for the descale, then put them back to default. Ive since gone to the driest setting and + 5 on the temp. Im interested to know why ( apart from servicing) the wetness is adjustable ?. Wouldnt a wet steam add excess water to the milk ? I would also have thought having the steam as hot as possible would be the best for quick milk work ?

              Wetness is often a problem and as there are different outcomes even though the same specs may be in place. Every thing has a tolerance... But if ya get an item that is within but on the low or high side for all bits, the outcome can / may not be what you want.

              The issues with teh earlier Em6900 was alack of control / need for group temp.. And feedback that the steam was wet.. In effect the same bit of code; thus easy to implement a software change that would allow the user some control.

              Again some got better than others... Machines perform slightly differently but in some cases that ability to change Group Temp / Wetness allowed the minor differences to be managed.

              Also a selling point and easily allows those who wish to play, to do just that. The red one at work is on DEFAULT and works like a charm. My other ones all needed a slight tweak to work the way I wanted them.

                Ill keep that in mind if I ever need to flush my steam wand. Still going strong thankfully.

                  I have found that the wetter the steam is, the more steam power you have.

                  Because the system uses a liquid (water) being passed through a thermoblock to change state to a gas (more volume) the pressure is reasonably proportional to the heat supplied and the amount of liquid being converted.

                  Taking it to the extreme, if you had maximum heat and no water, you wouldnt have any steam pressure at all.

                  The ability to vary the pump and the heat gives you the ability to find what works best for you.

                      Got it steaming like a trooper. Max temp and second wettest setting.

                        Its not advice, its a statement of unequivocal fact. Unless you mean that you would use balsamic :lol:

                        If anyone wants to explain why Sunbeam are wrong when they state in the manual that vinegar is an acceptable descaler Im all ears...  
                        Well on that point i would like you to try it yourself and let us all know how it goes.

                        The reason it says that in the manual i cant comprehend. But if you can spend $600-$700 on a coffee machine and then start taking short cuts for maintenance of the machine that i cant understand.

                        Maybe if you do stuff it up. Sunbeam will give you a new machine as you were just following their manual :

                        Anyway go with sunbeams manual and try it. And do let us know.
                        Good luck.  
                        Sorry, missed this post.

                        Already done - over 2.5 years in and going strong. I do use filtered water (Brita jug).
