La Marzocco Complete Water Tank for GS3 – Original Spare Part SA308.R
Fresh water, a tank that sits cleanly, and the GS3 draws from a full supply again. Water makes up most of every espresso, and its path through the machine begins in the tank.
La Marzocco lists SA308.R in the GS3 spare parts catalogue as a complete water tank («Complete Water Reservoir GS3»). The catalogue applies to the GS3 AV and the GS3 MP. La Marzocco does not list this part for other models. As a partner of La Marzocco, we obtain it from the official spare parts programme.
To us, the saturated group of the GS3 delivers a more refined aroma profile than an E61, regardless of the heating system. That is our observation. Our opinion is one of many.

Tip from the roastery: The GS3 responds to good water and fresh beans. For dense, chocolatey espresso we roast Cozy Chocolate and Nutty Delight, for maximum body without acidity Very Nutty. That is our recommendation, one of many.
