Troubleshooting-Gaggia-Super-Back-Leaking

From The Back

1. The leaking is coming from the water tank. If the water tank is not positioned properly it can cause water to continuously drain from the tank, even while the machine is turned off. This happens when the water tank is inserted far enough to open the release valve, but not far enough to seal with the intake line. This water can leak out from the water tank and end up on the bottom of the machine. This particular issue is usually indicated by lots of clear water leaking between the tank and the machine, and then leaking down the back side of the machine.
   1. Remove the water tank and make sure there isn't anything, such as coffee beans, which could be blocking the tank from seating properly.
   2. Firmly reinsert the tank into the machine and press firmly on it to make sure it creates a good seal with the intake line.
2. The grommet which seals the tank to the intake line is broken, dirty, or out of place. Remove the grommet, clean it off and inspect it for damage, and then reseat it into the machine. If reseating the grommet does not fix the leak then the grommet will need to be replaced. This document explains how to access the grommet and replace it.
