  • Unplug the machine and, once cooled, empty the water from the boiler.
  • With two 14mm open-end wrenches affiliate link, unscrew the two nuts above the piston that secure the lever.
  • Remove the two pins that hold the lever in place. If necessary, use a screwdriver.
  • Carefully store the pins to avoid losing them.
  • Remove the lever then tilt the machine on its side.
Warning
Carefully identify the removed nuts and pins to avoid any loss or reversal during reassembly.
  • Using a hook, remove the seal surrounding the shower screen under the piston.
  • Extract the shower screen by pushing on the piston rod.
  • Then, remove the piston.
  • Proceed with the piston maintenance: using the hook, remove the two piston seals. This may require some force.
  • On the machine, unscrew the two bolts holding the piston body.
  • Remove the piston body carefully. Be careful with the copper tube that extends into the boiler.
  • Unscrew the copper pipe from the piston body.
  • Using a tool or by hand, unscrew the plastic tip that holds the pipe.

With the machine disassembled, it’s time for cleaning.

  • Thoroughly scrub all the seals and the inside of the piston body with soapy degreasing water.
  • A toothbrush or a cloth will work perfectly.
  • Soak the copper pipe in white vinegar for 15 to 20 minutes to effectively descale it.

You can also put a few descaling tablets affiliate linkin the boiler.
I recommend doing this at this stage, as the tank is easier to empty and rinse when the piston head is disassembled.

Tip
Slightly heating the water in the boiler during descaling increases the effectiveness of the cleaning.

Once all the parts are clean, it’s time to reassemble the machine.
If some parts are worn, consider replacing them. For example, a La Pavoni gasket set affiliate linkmay be necessary.

Warning

Pay attention to the direction of mounting the gaskets on the piston: the wider parts must face outward.
Since the gaskets are difficult to put back, using a screwdriver can help.

  • Screw the plastic tip that connects the tube to the piston body.
  • Attach the copper tube to it, making sure to orient it correctly downward so that it dips properly into the boiler tank.
  • Grease the moving parts of the machine:
    • Apply food-grade grease around the piston and on its rod.
      Here is the type of grease to use affiliate link.
    • Add grease inside the piston body.
  • Reinsert the piston into the piston body.
    This is a bit difficult because the seals are very tight. A screwdriver can help.
  • Properly align the openings for the pins.
  • Place the seal around the shower screen.
  • Insert the shower screen and its gasket into the piston body.
  • Push the gasket in firmly (tip: insert the portafilter all the way to position it properly).
  • Replace the piston body on the boiler, without forgetting the gasket.
  • Tighten the two bolts securely.
  • Replace the lever respecting the direction of the holes.
  • Reinsert the pins and their fasteners (be careful with the small bearing, don’t forget it).
  • Tighten the two nuts on the piston rod with the 14mm wrenches.
  • Finally, adjust the lever movement height with the two nuts on the rod.
    If the piston descends too low, it risks hitting the shower screen and dislodging it.
