    coffee dispensing pressure gauge

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have a Grimac ILE Model (Twenty) The coffee dispensing pressure gauge in the manual said that it should be between 910 bars. It sits at 6 and when extracting it goes to 7. What do you think may be wrong? Any help would be greatly appreciated.

    Either the guage is wrong or the pressure is set too low.

    Re: coffee dispensing pressure gauge

    Thank you for your reply. Even when the machine is turned off and cold the coffee dispensing pressure gauge sits the same as when it is on, at 6 bars. It seems to be extracting espresso ok??? I am just worried that if there is a problem with the machine and i continue to use it it may make things worse. Any ideas on how to set the pressure gauge. Cheers dashadoo

    Ok, now weve established the gauge is wrong (not working).

    Sorry, Im no tech.
    Someone else will now have to take this further for you.

    Where did you buy it from ?

    Depending on teh cause (unknown) it may or may not make things worse to keep using.

    A blockage in teh line ? Or a gauge that is stuffed.

    Try 9Bar Espresso Services if your supplier is not able to play ball.

    Not necessarily.

    While your gauge may be stuffed these statements could be interpreted as, unless your machine is a tanked model, the gauge is reading line pressure and the pump is not working at full pressure. This could be either because it is stuffed or, if its a rotary, it is set too low.

    You need to test the gauge by eliminating the line pressure from the equation. With the machine cold disconnect your water line and see if the gauge then reads 0. If so then the odds go up that the gauge is reading correctly and the problem lies with the pump.

    Thank you all for the replies. I will do as you advised javaphile tomorrow. However the plot thickens....I just noticed that when i was doing the dishes and the kitchen sink tap was on (the water inlet for the machine is on the same line as the kitchen sink) the gauge went crazy. It went up when the tap was on and then went down when i turned the tap off. Any ideas? Cheers Gary
