    Isomac Tea II Deuo

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi Gang

    I just had the restrictor that they are now fitting to all Isomac machines installed to my Tea II The New model..This has made a big difference to the cooling flush and made the unit very stable no more water dance. If your having troubles with over heating and large cooling flushes this is what you need for the Fix ;) They cost less then $4.00 and you will be pleasantly surprised :o with the out come :)

    Cheers Gra..

    Re: Isomac Tea II Deuo

    Hmm, i have a TEA II but have never had any trouble with large cooling flushes. What does your steam pressure sit at after the element has cut out? Mine is 1.3bar, slowly goes down to about 1bar then element comes on and back up to 1.3bar. If your pressurestat is taking it up higher than 1.3 bar this may explain the need for large cooling flushes, in which case you could just adjust the pressurestat slightly i would imagine.

    What does this restrictor do exactly? Does it restrict flow of water into the group head? Does it affect your shots?

    Interested to hear more, thanks.

    Excellent news!

    Nice to hear they fixed what was said never to be a problem. Im surprised though that the issue is resolved solely by the addition of a restrictor. ;)

    My pressure stat is set at low side 1:0 high side2:2bar the trouble was the group over heating. I have a group head thermometer one of Erics and when left idling for awhile the group would rise to 102-103*
    and I would get a water dance and a flush of around 150ml...Not any more :)

    All I can say is that the restrictor is just part of the fine tuning for Isomacs even with bigger cooling flusher it still pulls great Shots.

    Did they do a redesign of the HX as well?

    Re: Isomac Tea II Deuo

    I purchased a Isomac Tea Due for demo purposes last week. Have it now along side fellow demo Rocket, Junior and Domus. Will be doing some testing and comparisons over the next week as well as probing the internals. Snobs are welcome to join in and drop in and say hi to the new addition.

    Had a interesting first bench test with it as the Isomac Tea Due was taken to a market and did 45 coffees across 4 hours without a hiccup or any problems...impressive considering the 1.2 Litre boiler!

    Most of the orders came in rushes with quiet lulls in between. Main allowance was that a Insulated Vacuum pot was used for long blacks. I wasnt able to attend due to commitments but three snobs were present : au_d2, Iamleon and Via and all sampled or produced goods on it! Would be good to get their thoughts posted. Happy snap also to follow! So test 1. Stress Test: (Multiple cups of coffee produced across short periods) check.

    Scace, internal and idle tests to follow. Oh plus the importer is sending me a bunch of different sized restrictors to tinkle with the Isomac with and look at results. *;D

    Good to hear Roger. I will be looking forward to your findings on further tests the restrictor that was sent to me made all the difference ;)

    To fit you have to remove the top thermosyphon tube from the back of the group to boiler it fits in the group end of the pipe..

    Just remember if you cross thread these fittings your in big trouble could be best to have it fitted by a Tech...

    Im curious - what does it read when left idling since the restrictor was installed? my DIY ~2.8mm restrictor has my Isomac idling at about 99 deg - I have the same thermometer from EricS.

    Looking forward to seeing your results from this although I suppose the Tea results might not translate exactly to the Mondiale given the different boiler size and whatever other differences there are between the two.

    It was great fun to use a "home machine" to pull shots at the markets. The small footprint allowed us to be more interactive with the customers, and allowed more bench space. Normally there would be a Veneziano A3 on the bench. *A Compak K-6 was on duty to deliver the grinds.

    Was surprised that the unit kept pace and pulled consistent shots, especially after a 8 shot rush (and having to top up the water in between). I was half expecting the unit to show signs of stress, but none at all. Pressure and temp were stable through multiple shots in a row. *A very handy drip tray with plenty of capacity and easy slide out removal.

    The only complaint was: ... who decided to name it the TEA .... every other customer would ask:

    "What machine is that?"
    "Its an Isomac TEA Duo"
    "Whats that? *a TEA did you say? * but does it make coffee?"
    "of course it does, let me show you ....."
    ;D ;D ;D

    well, I suppose that theyll remember the name easy enough. *.. " ah .. the TEA machine that makes bloody good coffee"

    Not necessarily
    A good water flush until the water stops spitting prior to pulling the shot is the first thing you should do

    However - It should be about 1.2 - 1.3 *

    If you dont know much about machines, then take it to a professional

    Please learn to spell espresso as it is not expresso *

    Hi Noel

    If the machine is under warranty then give the supplier a call to discuss, as fiddling around inside without the suppliers permission may void your warranty.

    Cheers!

    Again, have you spoken with the supplier? There may be some leniency applied.

    Statutory warranty should have it covered even if the manufacturer warranty has expired.

    Would have been less hassle if you had of taken it in sooner though ;)

    yes the new Mondiales includes restrictors that are available to be fitted to the earlier models. *I made my own and fitted that a while ago, but with official ones now available Id certainly recommend giving it a try if your Mondiale is running hot. *It should definitely help.
