  • Sometimes your espresso machine's group head needs a good clean. If your machine has a 3-way pressure release valve then you can clean it out with a brush and then use this blank portafilter basket to back flush through and clean out the inside of the group.

    53mm size fits all La Spaziale, Astoria CMA Plus 4 You, Wega Concept and Concept52 espresso machines.

    • Fits 53mm portafilters
    • Use with Cafiza® or similar cleaning product
  • Always follow manufacturer's cleaning and disassembly instructions. All mix ratios may be modified if a stronger solution is desired.

    Backflush (each group head):

    1. Insert blank filter in portafilter and add up to 1/2 teaspoon (3 g) of Cafiza® Powder. Insert portafilter into group head.
    2. Activate brew cycle for 10 seconds. Stop 10 seconds. Repeat 5 times.
    3. Remove portafilter. Activate brew cycle and rinse portafilter in stream of water from group head. Stop cycle.
    4. Insert portafilter into group head. Repeat step (2) without Cafiza® Powder 5 times.
    5. Make and discard a cup of espresso to ensure no residue remains.
