A backflush disc (also called a blind insert) blocks the holes in your portafilter basket, forcing water and cleaner backward through the group head’s internal valves and passageways. This removes rancid coffee residue that a simple water flush can’t reach. Unlike a dedicated metal blind basket, our silicone disc slides into the basket you already use, saving you money and drawer space. Plus, the soft silicone won’t jam or scratch the group gasket. 🔧 Will it fit my Breville Barista Express / Gaggia Classic / Rancilio Silvia? Yes! It’s designed for the 58mm basket standard used by these iconic home models. Simply place the disc flat inside your empty portafilter basket (single or double), lock it into the group head as usual, and run the backflush cycle. It also works with many 57mm baskets found on some Saeco and older Gaggia models — just press the disc gently to create a seal. If your basket measures about 2.2–2.3 inches inside diameter, you’re good to go. 🧼 How often should I backflush my semi-automatic espresso machine? For home use with daily brewing, we recommend a water-only backflush once a week to prevent oil buildup, and a chemical backflush using espresso machine cleaner powder (such as Cafiza) once a month, or after about 50–60 shots. If you notice your espresso starting to taste bitter or ashy, it’s definitely time. Our disc makes it so easy you’ll actually stick to the routine! 🚿 Is the silicone disc dishwasher safe? Will it absorb odors? Absolutely dishwasher safe – top rack or bottom. The platinum-cured silicone is non-porous, so it won’t absorb coffee oils, detergent smells, or develop a slimy feel over time. If washed by hand, a quick rinse with warm water and soap does the job. It’s also heat-resistant up to 450°F, so it handles the hottest brew water without warping. ✨ Can I use this disc with cleaning powders like Cafiza or Puly Caff? Yes, and that’s exactly what it’s made for. Add a small amount of approved espresso machine cleaner into the blind basket (with the disc in place), lock the portafilter, and follow your machine’s backflushing sequence. The silicone creates a perfect seal so the cleaning solution foams through the entire hydraulic circuit. Just be sure to rinse thoroughly with a few clear water backflushes afterward.
