    Rocket Giotto tar buildup

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I've had my Giotto 2 years now and am very happy with it. I've scrupulously backwashed it monthly with espresso machine detergent as per the manual.
    When the group head started leaking I decided it was time to replace the gasket.
    I was astonished when I removed the filter and gasket to discover a layer of tar, for lack of a better description, several millimetres thick blocking most of the holes at the back of the filter. Despite soaking it in boiling detergent, it required the use of a flat bladed screwdriver to remove it. I then spent the best part of an hour with wooden skewers and toothpicks to unblock the holes.
    Long story short: If you have one of these machines. or a machine with a similar head, periodically remove the seal and clean the back of the filter, as monthly backwashing with detergent does not remove it.

    That's why we recommend a daily water backflush and weekly chemical backflush

    As in backflush detergent such as Clean machine or Cafetto- to name a couple.

    Second the above routine - I have a Diadema Reale (very similar machine) which I water back flush after basically every shot, and detergent clean about once a week/fortnight. My first group seal change only needed to be done after 5 years - and when the screen came out with the old seal it was pristine behind it

    Interesting. I have a Giotto of similar age and I have this build up on my filters too. I remove the filter when I clean the machine (roughly every 2 months), soak it in Cafetto and then give it a good scrub. I replace the gasket and filter about annually.

    Talk_Coffee - I am interested in your recommendation that I should be cleaning with Cafetto weekly. My machine gets fairly light use - maybe 10-12 double shots a week. Would you still recommend weekly cleaning? Fortnightly? Monthly?

    Weekly- even if you make one coffee that week. Oils build up and become rancid.
