We’ve assembled a variety of importer recommended basic parts you may require to service the group and valves of some of our espresso mahcine range.
Whilst these kits won’t allow for a comprehensive service, they’re a start and may well help you to prolong the service interval for your machine. When we service a machine, we do a whole lot more. Note that any work you perform is at your own risk. Nevertheless, there are plenty of good online video resources.
Our service kit is currently offered in a variety of configurations and includes the major seals, gaskets and wear components required to attend to the group and valves of your espresso machine at home. Please note that we would not recommend that you attempt any works while your machine is under warranty. This is by no means a comprehensive service. We also advise that we do sometimes notice variation in some components- in particular slight variations: for example in the length of group valves and diameter of some teflon seals. We cannot accept responsibility for any slight variations which may be present in your own machine and advise that these kits are purchased at your own risk. They are supplied as we receive them from importers. We do not accept returns on service kits under any circumstances.
Current offering:
Our service kits now all include a shower screen and 8.5mm silicon group seal as well as a thin, green mushroom o-ring (these are by far the most common fitment we use). On request you may substitute an 8mm group seal if preferred/required as well as the thicker orange o-ring which is used on Rocket Espresso variants which have a ceramic mushroom. Please let us know of any substitutions by adding any variations to your cart when you order.

What else will I require?
- You may require a group seal pick to remove your existing one if it’s perished. NB install your group seal with bevelled edge facing upwards. Clean well before you install and use a little detergent to help seat the seal. Fit completely by removing the basket of your portafilter and locking it into the group and then repeat with the basket loaded into your portafilter.
- If your group pins/pistons are worn, you will probably require new ones. In addition, they can break when seal replacement is attempted. Assuming you can safely remove the pins, polish the ends up with some wet/dry to get them really smooth and flat. NB VBM uses a proprietary kit. Lubricate all moving (friction) surfaces with food grade grease.
- Likewise for your leva cam. If it’s looking tired and grooved or worn, replace it. Lubricate contact surfaces.
- Exploded diagram/s if available (or take photos as you go so you know how to reassemble)
- Spanners and other tools
- Anti-vacuum valve if yours is leaking. Please note some Izzo anti-vacuum valves are barbed and perhaps a safety valve if yours is leaking
- Food grade grease
