    Diadema thermostat problem

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Recently I had to replace the heating element on a Diadema Junior Leva.
    Since the new element (1400W) has been installed, the machine thermostat is cycling on and off way too frequently.
    By this I mean instead of clicking into gear at about 0.9 bar, and then clicking off at about 1.1 bar, it is cycling on and off between 1.05 and 1.1 bar.
    At this rate Im sure it will wear out about 4 times faster than it should.
    Im guessing (hoping) there is probably a simple adjustment to correct this setting...anyone ??

    I wouldnt say that itll wear out faster. I would think it just made your machine more stable!

    Agreed- you have an improved pressurestat with a smaller deadband...Consider yourself a winner!

    Pardon my ignorance, but does this mean that the pressurestat is integral to the heating element , and not a separate device as I had thought ?
    eg) The element was changed but nothing else was adjusted, and now I hear a very repetitive click click click as the machine maintains the narrow band between 1.05 -1.1 bar.
    Thanks for the advice, as always it seems a solution is never far away on the CS site!

    oops- poorly read in my case! :-[ How an element would influence that, Im not so sure- but then there is a lot Im not so sure about....At any rate, the smaller dead band is a good thing....

    Yep,

    Agree with Chris, a taught deadband is a very good thing to have. The reason for the shorter cycling than youve been used to could be to do with the weather turning suddenly cooler. We went from daytime temps in the high 20s here to sub 10 in a single day.... could have something to do with it :-?.

    If you want to work around this, the only really effective measure is to insulate your boiler but I wouldnt do this if your machine is still under warranty. You could always ask the vendor you bought it from if they could insulate it for you but I wouldnt fancy your chances ;)
