La Marzocco Shower Screen with Lion Logo

Genuine La Marzocco reinforced shower screen, part number F.3.040, featuring the iconic lion logo and precision cut stainless steel construction to keep every shot extracting evenly.

The shower screen might be one of the smallest parts in a La Marzocco group, but it does a job that punches well above its size. Sitting directly above the puck, it spreads incoming water evenly across the coffee bed so the whole dose saturates at the same rate. Over time, mineral scale and coffee oils build up on the surface, and once that happens, water starts finding the path of least resistance rather than distributing evenly, which shows up in the cup as inconsistent, uneven extraction no matter how dialled in your grind and dose already are.

This is the genuine La Marzocco part, precision cut from reinforced stainless steel and stamped with the brand's iconic lion logo. It's built to replace the older L107 screen and fits across La Marzocco's current range, giving you a straightforward, reliable maintenance swap during routine group servicing. Because it's made from thicker, reinforced stainless steel, it holds its shape well under repeated use and resists the bending or tearing that can happen with lower quality aftermarket alternatives.

Whether you're carrying out scheduled preventative maintenance on a busy multi-group site or simply replacing a screen that's showing its age, this genuine part restores full, even water distribution and helps bring extraction consistency back where it should be. It's a small, inexpensive fix that makes a real difference to shot quality, and one worth keeping on hand as a routine spare.

What does a shower screen do?
It sits at the top of the group and spreads incoming water evenly across the coffee puck, so the whole bed saturates at the same rate during extraction.

How do I know if my shower screen needs replacing?
Signs include visible scale or oil buildup, discolouration, warping, or extraction that's become uneven or inconsistent despite unchanged grind, dose and prep.

How often should the shower screen be replaced?
This depends on water hardness, usage volume and cleaning routine, but most sites replace it as part of scheduled group maintenance rather than waiting for a visible fault, with busier cafés typically needing more frequent replacement.

Is this a genuine La Marzocco part?
Yes, this is the genuine part, F.3.040, stamped with the La Marzocco lion logo, made in Italy.

Does this replace an older screen?
Yes, this reinforced screen replaces the earlier La Marzocco part L107.

Will this fit my La Marzocco machine?
It fits across La Marzocco's current espresso machine range. Note that the KB90's Straight-In group uses a separate specific shower screen, so if you're servicing a KB90, check you're ordering the correct part for that machine.

Can I fit this myself?
Yes, it's a straightforward swap as part of a standard group service, and can be fitted by a confident barista or technician alongside a group gasket replacement.

Does a worn shower screen affect flavour?
Indirectly, yes. A worn or clogged screen leads to uneven water distribution and channelling, which can show up in the cup as sourness, bitterness or a flat, inconsistent crema.
