Bezzera Unica: Leaking from the Steam Wand or Hot Water Tap

Learn what to do when a Bezzera Unica espresso machine is leaking from the steam wand or hot water tap.

  1. If either wand is leaking from the end of the wand, it means the steam/hot water valve is not fully closed.
      • Make sure the knob is securely in the closed position.
      • If the knob feels loose, or doesn't appear to be properly engaging, then there may be a loose or broken part in the knob assembly.
      • Descale the machine. Scale buildup inside of the steam/hot water valves will prevent the valves from closing fully.
      • If the leaking persists, then the corresponding valve may need to be replaced.
  1. If the wand is leaking between the tip and the arm of the wand during use, there is an O-ring that is broken, missing, or out of position. Remove the tip on the wand that is leaking. The steam wand will have an O-ring between the tip and the wand. Inspect the O-ring to make sure it is clean. Replace the O-ring if it is damaged or broken.
  2. If the wand is leaking from the ball joint, then there may be an O-ring that is worn out or out of position.
