6) Cleaning the diffuser screen
- Due to filter holder discharge operations
(subsequent to coffee brewing), a certain
amount of coffee grounds may slowly
build-up on and obstruct, even partially,
the diffuser screen. To clean it, you must
first remove it by unscrewing the diffuser
screw.
- Put 2 or 3 teaspoons of cleaning
detergent for coffee machines in about
1/2 a litre of water inside a heat-resistant
container and boil.
- Place the diffuser screen(s) and diffuser
screw(s) in the solution and leave them
fully submerged for about 30 minutes.
Rinse thoroughly with clean water. Install
and run hot water through each group
several times with the screen installed.

Please see the documentation accompanying
the water filter/softener for proper operating
and cleaning instructions.
