Collection: GS3 Group Head
Browse group head parts for the La Marzocco GS3 at Coffee Addicts. We stock the spares Canadian espresso owners reach for most, so you can fix a problem at home instead of booking a service call. Everything ships from Canada with fast, trackable delivery, and if you are not sure which part you need, our team knows these machines and can help you get it right the first time.
When to replace group head parts
On most machines the group head is where water meets the coffee, so worn parts here show up fast as leaks, poor pressure and channelled shots. In this collection you'll find group gaskets, seals, screens and shower screens, dispersion parts and mounting hardware. If you're dealing with water leaking around the portafilter, a group that won't seal, or espresso that pours weak and uneven, replacing the worn part here is usually a straightforward DIY fix that restores performance.
Not every part fits every version of this machine. When in doubt, send us your model and serial details and our team will make sure you get a part that fits.
