    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).

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

    Im interested to know why ( apart from servicing) the wetness is adjustable ?.
    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.

    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.
    Cheers

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

    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.

    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]

    Im doing the vinegar flush at the moment, purely as a maintenace thing, as the original flush I did worked well. I thought it couldnt hurt to do it now while its working well. See what happens hey.

    Do you reckon that makes a difference to the performance of the descaler ( any descaler).?
    One part of me says YES..

    BUT... Copper is used through out many systems including commercial machines... It may look like a nice SS steam wand and some may be... But most are copper and plated. In addition (ignore the boiler) the lines are usually copper.


    I am going to go out on a limb and suggest that with the finer bore and heat thransfer back to the Steam pump and teh special OP Steam valve etc That SS is an improvement that implemented to reduce... NOT solve but to reduce issues.


    I have had to unblock a couple of old units... And often get that green gunge appear and then all is OK. In particular, after sitting for some time. I would SUGGEST (can not prove) that SS would not be as bad.
