How to change your espresso machine’s brew head seal

Pro tip: Before you begin, turn your machine on and let it heat up. Once it has heated up turn off and unplug the machine, then follow the instructions. This will make it easier to unscrew the filter.

  1. Remove the attachments (drip tray, water reservoir, filter handle … etc)
  2. Turn the machine upside down
  3. Unscrew the filter
  4. Remove filter and the old seal
  5. Wash the filter
  6. Fit the new seal and put it back together

Things to check before replacing the seal

  1. Is your coffee ground to fine? this will create to much pressure in side the filter cup forcing the fluid out of the sides instead of the bottom
  2. Is your dual walled filter blocked? you can check this by fitting your dual walled filter cup to the machine, with out coffee in it. If your machine still leaks their is a blockage in between the filter cups two layers.
  3. Is your brew head collar worn down? When the filter and filter handle is securely fitted to you espresso machine, the handle should be positioned in the centre (or just past the centre, to the right). If your handle easily pulls to the extreme right it is likely that your brew head collar is worn down and needs to be replaced along with the seal. This can be a particularly involved solution; you may want to consider taking your machine to a espresso machine service agent.
