    Gaggia Classic PID Steam Control

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi guys,
    Im thinking of getting a PID for my Gaggia Classic.
    Ive done some research but I could not see anyone mentioning about steam temperature control.
    Is it possible to control the steam temperature with a PID installed?
    Will it improve the quality of froth? because my Classic loses steam power after 10 seconds turning on.


    Thanks in advance ;)

    Welcome Justin... [smiley=thumbsup.gif]

    I just used the Quick Search tool up in the top l/h corner of the page and came up with this... http://tinyurl.com/3gfpqmn What works for Silvia and other Dual Purpose Single Boiler machines will work in principle with the Classic too.... 8-)

    Lots to read through in there mate ;)

    if the PID has inverted alarm output (relay on until alarm point reached) wired to heater via steam switch, that can be used to control steam temp, it wont be PID, just simple on or off as it crosses the alarm set point, usually 40C above brew temp ,or what ever you set alarm set point too.

    I did this to my gaggia baby, which is very similar to the classic

    I read somewhere, maybe here, that if you open the steam knob just before the thermostat turns off the element and you steam with the element on you get plenty of steam.
    The temperature readout on the pid will help you do that.

    Yep, home to roast and firepower are correct. I have a basic pid on my classic and if I start steaming approximately 15 degrees before the steam thermostat trips, the heater element is* on all the time I am steaming. If I leave it any later, then it cuts out part way through and I lose steam pressure.
    I dont make very many milk drinks, so can live with this, but am thinking of doing the pid alarm mod as it would make life easier.

    Good advice.

    Is there any danger of running out of water in the boiler?

    Probably not if youre only doing the one jug. Re-prime and youre good to go again.

    Highly unlikely. If you kept steaming for long enough (minutes on end) it is technically possible, but still unlikely to cause damage due to the design of the element which is not immersed in water, but encased in aluminium.

    If you ran out of water, the temp would rise faster and the steam thermostat would cut power to the element.
