Replacement shower screen (hand shower) for Nuova Simonelli espresso coffee machines, original code 9.002.504.

• Type: shower screen/disc for the brew group
• Compatibility: Nuova Simonelli espresso coffee machines

The shower screen is the perforated disc fitted under the group head shower: its job is to evenly distribute the hot water over the ground coffee puck during extraction, ensuring a uniform infusion. Over time it clogs with coffee residue and limescale, causing uneven extraction or water leaking from the sides of the portafilter; it should be replaced periodically together with cleaning the group whenever water leaks are noticed at the portafilter sides or extraction becomes uneven.
