Introduction
There are at least 2 major differences in La Pavonis Domus Bar. The model is close or similar to Lelit Anita.
But the newer models of Domus Bar (DMB) and Anita have a different brewing group than the older ones (slightly improved for replacements). This guide is for the older version, as far as I could find, from before 2007.
The new seal has the following dimensions:
71,5 x 54 x 4 mm
Tools
Parts
-
-
Use your fingers or something else to put some pressure on the wrench and the nut, so you don’t tear it.
-
The nut is quite flat, but you can open it with a 14mm wrench when you angle the wrench so it fits between the openings in the group case.
-
Put the coffee machine in the back or if you can remove the bean collector, on the top.
-
Remember to empty the water canister, the spill collectors. Turn off your machine and disconnect it from power.
-
You don't need to open the machine for replacing the seal.
-
-
-
Once the nut is removed, you’re able to remove the filter by prying it off.
-
I recommend to do it from the sides and only if it’s an never serviced machine, you need to use some force.
-
Clean the filter or replace it if damaged. You can also clean the brass element behind the filter.
-
-
-
Remove the seal by prying it out of the group set.
-
Make use of the cutouts in the group casing.
-
Older seals can dry out and might break. That’s no problem as you need to replace the seal anyway.
-
When adding the new seal, use the guide backwards. Make sure the seal fits well. Don’t tighten the copper screw too hard and clean or service the machine regularly.

To reassemble your device, follow these instructions in reverse order.
