    Loss of Steam Power on HX machine

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

    I have a Diadema Junior semi-auto which I have been using for about 6 months. When I first got the machine I was really impressed with the steam power and how quickly I could steam milk (almost too quick ;))

    Anyhow, many coffees later I find that it seems to take much longer to steam my milk. In fact it is taking around 90 seconds just to steam enough for two small coffees! This is less than half full in a tiny little (4oz?) pitcher.

    The possibilities as I see them are:
    • I am imagining it and this is how long it should take
    • There is some maintenance that I have missed to clean out the steam system?
    • The steam pressure of these machines reduces over time?
    • There is a valve/seal etc.. in need of replacement and I better get it to my repairer.


    Has anyone else had a similar experience with their HX machine?

    Thanks in advance.

    Matty,

    Have you cleaned the small holes in the stream tip?

    Even if you wipe down the wand and blast some steam out after texturing your milk, milk solids build up in the holes over time, reducing the volume of steam which can pass into the milk.....

    Less steam means less heat and far reduced texturing ability.

    Thanks for that.

    I wipe the wand thoroughly (including the end) every time I steam. I also scrub the end of wand every week or so, but I dont poke anything into the steam holes.

    Any tips on the best type of implement for this? Straightened out paperclip perhaps?

    Cheers,
    Matt

    Matt,

    Yep, paper clip, piece of thin wire even something like thick fishing line should work OK....

    I use a small sub mm drill bit just inserted by hand..... this has the added advantage that the flutes on the bit drag out the "gunk"....

    But as long as it fits and wont jam in the hole (or even worse snap off blocking the hole) it should be fine.

    Removing the tip and soaking in backflush solution along with baskets etc will work too.

    Thanks guys - you hit the nail on the head :)

    From time to time I soak the steam tip in cleaning solution, but dont usually clean out the steam holes. After a quick going over with the paperclip, steam power is back to what it used to be.

    Milk for two small drinks takes about half as long as it did! What a difference.

    Gday Matty P,

    Theres also a series of very small diameter tip cleaners designed to clean out the gas orifices on oxy-acetylene torch burner tips and the like. They come in a little pocket sized folding enclosure which includes a wide range of sizes.

    Cheers :),
    Mal.

    Matty P,

    Bombora sells a special Milk Steam Solution. I have use it in my milk jugs and is pretty good. May be you should use this every 4 months.
