La Marzocco Linea Mini: Steam Gauge ReplacementUpdated 5 months ago

You'll need:

14mm Wrench

16mm Wrench

Before getting to the gauge, you'll need to remove your panels. 

Once inside, take a look at the left side of the machine. You'll see the steam gauge, and its capillary tube connected to the side of the boiler.

Use the 14mm wrench to loosen the nut on the back of the bracket that is holding the gauge tight to the face of the machine. Once loose, you can use your fingers to unscrew the nut the rest of the way. 

Slide the bracket back, off of the threading. There is a slot in the bracket to pull it off of the capillary tube. Slide the bracket off of the copper capillary tube, and set it aside for later.

Now turn your attention to the connection at the steam boiler. Use the 16mm wrench to loosen the nut here. Again, once loose, you can use your hand to unscrew the rest of the way. 

Now that your gauge is fully free, you can pull the gauge out through the hole in the front face of the machine. 

Now you can feed the replacement gauge back through the opening, following these instructions in reverse order to reinstall. If you have any questions, reach out to us at [email protected].
