    Re: Mystery machine

    I wouldnt leave the detergent/blind filter on the group that long. The heat of the group will dry the detergent into place & make it difficult to strip it out on flushing with water only.

    A better way of doing this is to apply the detergent with a little water in blind filter to the group, leave it locked into place (WITHOUT ofcourse activating the group/pump), but only until the detergent stops foaming out the exhaust. This might only be a couple or so minutes...depends.

    In any case you watch it and start flushing once the foaming has stopped.

      any one have any idea what the 18 month old millenium at work would be worth (clean and working well)- may have a buyer- to save it from further mishap?

        From memory the RRP of a new millenium is somewhere around 22 or 2300.00.

        Without seeing it, may I suggest that a fair price for both buyer & vendor could be in the vicinity of $1500.00 or $1600.00...no? Any less and I think the school loses out unnecessarily.

        Wouldnt it be a better idea for the school to arrange proper training for those responsible for the machine, and keep it?  We deal with quite a few schools and their espresso machines are in the care & control of only a couple of people at each site, usually the teacher & aide running the hospitality course, and they really dont have any problems when managed in this way (ie when managed by a restricted number of "responsible" staff only).

          thanks FC
          i had said $1500 as a as a rough 60% before i posted this - but didnt really know
          we have a few people interested but whether theyll buy?

          re keeping it- with it the way it gets in between my surgery (read maintenance) the coffee from my sons saeco via venezia is superior- and id be happy to have coffee before and after work on my (clean) machines at home!

          it just seems a pity for such a lovely thing to get like this- also workplace runs on such a shoestring budget (small private school) so training apart from via me out of question (no you dont steam from hot water outlet, no you dont fill large containers from water outlet, you have to wait for the machine to heat up, have to purge steam arm of steam and much afterwards etc etc- minor stuff for a pro instructor!!!)

          many thanks

            Whoops, sorry! I didnt think anyone would take that suggestion verbatim. Well spotted, Attilio!

            Of course, what I meant was to do a clean water backflush or two first, then to put a bit of detergent in the blind filter, do a quick blip of a backflush (enough to discharge some foamy water), then to leave the blind filter in place with the detergent in solution and without the pump running. To find out how long to leave it for, you could always let it sit for three minutes, then pull it out, dump, do a clean water backflush and then repeat, noting how much crud the detergent solution dissolves each time. As long as the pump isnt running and as long as the detergent is in solution, you cant hurt the machine.

            Cheers,

            Luca
