  • Unplug the power cord!
  • Remove all attachments such as water tank, pulp drawer, brew group.
  • Turn the machine with the back facing you.
  • Remove five Torx T20 security screws.

Step 4

              Repair left side water leak
  • The leak is easy to recognize from the traces of lime under the heater.
  • A leaking expansion chamber is usually the cause. But also check whether the connections on the heater are not leaking. The water may also come from above, e.g. from the upper brewing flask.
  • If too much water is running in/through the expansion chamber to the drip tray outlet or next to it, you can check where it’s coming from by unplugging the silicone hoses. You may need to replace one of the following components:
  • from a defective pressure relief valve in front of the heater
  • from a leaking steam valve
  • from the upper brew piston if it is defective/leaky
  • If you start the machine - with all caution - you can observe where the water comes from. Immediately pull out the power plug.

Step 5

  • The lower front panel still has to be removed. To do this, loosen the two Phillips screws on both sides.
  • The bezel is still snapped in at the bottom left vertical inner side. Release the catches and carefully lift the panel past the coffee spout.

Step 8

  • Unscrew the two Phillips screws that hold the steam valve in place. Note the washer on the right screw.
  • The steam valve is now loose so that the expansion chamber can be lifted out in the next step.

Step 9

  • Unscrew the three Phillips screws on the expansion chamber and the heater. Pay attention to the upper one, it is particularly long.
  • Pull off the two silicone hoses.

Step 10

  • The expansion chamber and heater unit is basically free. But it’s still pretty stuck. Try prying it loose at the spout.
  • When it’s loose, you can gently pry it out.

When it’s loose, you can gently pry it out.

Step 11

  • This is what the chamber and heater look like from below. There is no rubber seal, the chamber is simply snapped on. In many cases this is not enough and the water leaks out. There is no suitable seal. You can try to seal them with a piece of household rubber, for example.
  • Clean the chamber and remove any traces of lime.

Step 12

  • Get household rubber rings of the appropriate length. If you can’t find a single one that’s longer, two shorter ones will do.
  • Cut the rings and place them in the groove on the edge of the expansion vessel as a test. If they fit, stick them in place with a few drops of all-purpose glue.
  • Carefully reinsert the expansion chamber, assemble everything and then test whether everything is tight.

Als Dichtung eignet sich Silikonschlauch Außen 3mm x Innen 2mm hervorragend. Ein Stück von 15-20cm ist ausreichend. Wichtig ist ja vor allem der untere Bereich.

Any Type of thin silicon hose like this one.

Ok; do you think it would be better to cut the hose in the direction of the length, in order to wrap the other piece of plastic? or it has to be put in the slot as it is?

Use it, as it is. I myself took a normal rubber band from the kitchen and it worked.
