The 9Barista Mk.2 Overheat Repair Kit is designed for situations where your espresso machine has been left on the heat for too long and has become overheated. When this happens, several internal components may need to be replaced to restore your machine to full working condition.

This kit contains a complete set of genuine 9Barista Mk.2 replacement parts needed to get your machine up and running again. It includes:

1x Safety valve (assembled with safety ring)
1x Group insulator
1x Valve chamber seal
1x Valve pin and seal
1x Mk.2 boiler O-ring
1x Upper chamber O-ring
1x Valve body seal
1x Main valve spring

Note: The grouphead O-ring is not included.

To complete the repair, you’ll need a 3mm Allen/hex key and a 13mm spanner or wrench. Step-by-step instructions are available on the 9Barista website.

Before purchasing, check that your heat transfer plate is not damaged or warped, as this can also affect performance.

Instructions on how to do this can be found here.
