The great news is that you can replace all the external seals and parts easily at home. There are 5 external seals on on TLG that you can change at home.
- The little guy - Group Head Seal
- The little guy - Boiler cap O-ring
- The little guy - Steam Pin O-Ring
- The little guy - Steam Tip O-ring
- The little guy - Steam seat O-ring
How often should I replace the seals?
Depends on how often you use TLG and how careful you are. On average, we would expect the following:
Boiler Cap seal and the Group Head Seal are the two major seals in the machine. They make sure that the machine creates correct pressure. they need to be reguraly cleaned in the case of the Boiler Cap seal lubricated.
- The Group Head seal should be replaced every 12 months to 24 months.
- The Boiler Cap seal should last 6 to 12 months and should be replaced regularly. Some customers have managed to keep the same boiler cap seal for between 2 to 5 years by being careful and not over-tighten when filling with water. Also, adding a little cooking oil to moisten it now and again will help. Hand tightening rather than using the group handle also helps. Caution, if the boiler ring is too hard it may not seal correctly.
- All other external seals should last 3 to 5 years.
If you leave the machine on heat and it dry's out and damages all the internals, this is a major problem, and the machine will need to be fully rebuilt.
How do I clean TLG?

What happens if I leave the machine on the stove?
Unfortunately, this is not covered under warranty. We get very few machines back like this, so it is good to know that people take care of their machines and don't do this. The cost of a full rebuild is high - so try not to forget your machine on the stove :).
Please note: A full rebuild requires Internal repairs and should only be attempted by qualified technicians. TLG requires special tools to open and service. After servicing, special equipment is required to pressure test the unit to make sure it is operating correctly.

If you are using your own ground coffee - Use the normal basket (not the Supermarket Basket) we recommend between 22 and 24 grams of coffee; it will depend on the roast profile you use and how you grind your coffee. Double tamping is the best way to get consistent double shots.
Measure your coffee out, fill the basket and tamp. Then top up the basket with the remaining coffee and tamp again. The pressure for tamping should be quite forceful.
As with professional coffee machines, there is a little bit of experimentation to get what each individual likes as the perfect shot.
Note: If the coffee is a little older, then slightly more coffee is needed.
Also, grind size affects extraction and, therefore, the overall flavour and quality of each cup of coffee. When experimenting with grind size, make sure you only make very small changes to the grinder adjustments.
Light roasts are less porous than darker ones, so their compounds extract more slowly. So you will need to adjust the grind level.
When coffee is ground finer, it has more surface exposure. This means that extraction will happen more quickly. Remember very small changes until you get it perfect.
So if you are using light roast, grind it a little finer. If you using darker beans, use a coarser grind size.
That is precisely how professional baristas do it in a cafe.
