    Group head leak with naked pf

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I bought a naked pf for a Silvia a few days ago and Ive been enjoying it except Ive started noticing it leaks around the group head when pulling a shot. I dont notice then when using the Silvias own pf. Anyone know if its more likely the standard pf is masking the problem or the naked pf is a poor fit, is this a common problem?

    Make sure you have cleaned the Group head and that ya seal is all OK.

    Use teh same basket in both and try each group handle a few times..

    Do it one at a time and keep a record of what went here etc.

    Swapping baskets and handles should allow you to prove either

    1: Dirty group head
    2: Basket
    3: Group handle
    4: Seal
    5: User

    Re: Group head leak with naked pf

    is it a real Rancilio one?

    I have the same issue with a PF that "fits" but is not the same brand as the machine (not a rancilio machine)........ slight leak when making coffee

    i use it for my blind holder........

    No, its not a real Rancilio one. Ive been googling this morning and it seems quite a common issue. Ive just had several more goes on it, making sure everything is clean, basket in properly etc, and Ive found that pushing it to the right more just about stops the leaks. In fact Ive done this twice now and I think that was the issue.

    Then teh issue is teh depth and position of teh lugs..

    As per usual.. 2 + 2 = 5 Coffee is not by numbers and gauges and position of wands and handles etc are only guides. Every thing is dynamic.

    But at least ya got it sorted.

    The next step is consistency.. Then try with ya eyes closed.. :o


    Seriously... Watched a friend of a mate change grind / tamp and then do a shot.. He was slow... BUT good.

    I bought one from coffeeparts a long time ago for Silvia. If you grab a caliper and measure the top of the PF to the lugs, youll find it is just a tad skinnier than the Rancilio original. So when you snug it in, it doesnt push on the dented seal quite as hard as the original. So it leaks a bit.

    I resolved this by the careful application of a slight amount of brute force ;) This works for me for the LM double basket, but not for the single basket which is also a hair skinnier. So the single leaks unless I really heave it hard.

    Ive learnt to basically live with it. Compared to drinking crappy coffee, this is small beer ::)
