Core Benefits for Extraction & Maintenance

The A.5.110 Diffuser Screw is a critical component for baristas solving "uneven water distribution on espresso puck" or "poor espresso extraction" issues.

• Enhanced Steam Flush: The modified internal geometry facilitates a more efficient cleaning cycle, crucial for high-volume environments where group head hygiene is paramount.

• Advanced Backflushing: Designed to allow deep cleaning of the shower screen without total disassembly. When used with a blind basket, the screw optimizes water turbulence to dislodge coffee oils and grounds.

• Eliminate Channeling: By ensuring uniform water dispersion across the screen, the A.5.110 prevents the "clogged group head" symptoms that lead to bitter, inconsistent shots.

Installation & Maintenance Tip

To resolve a "leaking espresso machine shower screen" or "clogged group head," simply swap your existing L106/V with the A.5.110. Regular backflushing with this screw maintains peak machine efficiency and flavor profile, reducing the need for costly service calls.
