If 9Barista Mk.2 is left on the cooker for a long time and has gotten very hot, a few components may be damaged and need replacing.

This kit contains a complete set of parts to get your machine up and running again. The items included are listed below:

• 1 x safety valve (assembled with safety ring)
• 1 x group insulator
• 1 x valve chamber seal
• 1 x valve pin and seal
• 1 x Mk.2 boiler O-ring
• 1 x upper chamber O-ring
• 1 x valve body seal
• 1 x main valve spring

(The Grouphead o-ring is not included)

You will also need a 3mm Allen/hex, and a 13mm spanner/wrench to open the machine up and replace the components. Instructions on how to do this can be found here.

It is worth checking, before purchasing, that your heat transfer plate is not damaged or warped in any way as this can also impact the performance of the machine.

Compatability:

9Barista Mk.1: No
9Barista Mk.2: Yes
