Clean group screen, check and replace group seal
The group screen helps to disperse the incoming hot water onto the coffee bed and also prevents
coffee particles entering the group.
The black group seal will remain flexible for a long time but will harden eventually. We advise to check
the group seal regularly and replace when it hardens or shows cracks.
Procedure
1. Pry the group screen gently from the group using the screen extractor levered under the bayonet-
ring. Place the pointed edge of the tool
in the rim of the group screen (see
), do not
puncture the group screen. Pry left and right, the screen will fall out together with the group seal.
2. Remove the group seal from the group screen.
3. Soak the metal group screen in a solution of coffee dissolving powder and warm water for about 5
minutes. Clean with firm brush and rinse under streaming water.
4. Check the group seal for cracks and/or hardening, replace if necessary.
5. One side of the group seal has a somewhat more rounded edges. When replacing the group seal
on the group screen, make sure the rounded side of the ring is inserted into the group (facing
upwards, see
).
6. Place the group screen with group seal on the filter holder and insert into group, pushing upwards.
7. Turn the filter holder in the bayonet lock to firmly press the group seal into the group.
