Disassembly Instructions

You may occasionally wish to disassemble your 9Barista machine to either replace or upgrade a component. We’ll show you how to do that here.

Tools required

  • 3mm Hex key
  • 13mm spanner/wrench (only if you need to remove the Safety valve or Boiler pipe)
  • T10 Torx screw driver (only if you need to remove the Chimney)

Step 1

Remove the Portafilter and unscrew the Boiler until you feel the Boiler o-ring disengage. There will be about a 3mm gap between the top of the Boiler and the bottom of the Group head.

Step 2

Unscrew the three Group head screws using the 3mm Hex key. The Group insulator will spring up once the last screw is removed.

You will now be able to remove the Group insulator, the Group head o-ring and the Valve chamber seal.

Step 3

Lift the Group head off, and take out the Valve pin and the Valve spring.

Step 4

Finally, twist the Heat exchanger anti-clockwise to remove it from the Boiler. From this point replacing any individual component should be straight forward.

Step 5

Perform the following maintenance checks:

  • Check for any signs of damage to any of the o-rings, and replace if necessary.
  • Check for a blockage in the Heat exchanger coil by blowing into the boiler pipe. You should be able to blow a small amount of air through. If you can, there’s no blockage.
  • If you can’t blow through the boiler pipe, unscrew it and see if there’s any debris blocking the end. If there is, use a pin to dislodge and remove it, before screwing back into place. Tightening it with your fingers should be sufficient; turn until you feel resistance against the thermal break.

Step 6

Reassemble the machine by following the steps 1 to 4 in reverse order.

When you come to fitting the Group insulator, be careful that the Valve chamber seal locates correctly. To do this, position the Valve chamber seal around the tip of the Group insulator, and then press the these two parts on to the Group head. If the Group Insulator is pushed up by the spring before you attach one of the three screws, the valve chamber seal may have dislodged.

Once the machine is reassembled, check that there is a uniform gap between the top of the Boiler and the bottom of the Group head. If there isn’t you may not have fully tightened all of the three Group head screws.
