Cleaning the gasket and shower plate
While making espresso, coffee grounds will naturally accumulate on the group’s sealing surface.
Allowing an excessive amount of grounds to build up can prevent the portafilter from properly sealing
to the group head. In extreme cases, such as leaving a used portafilter in the group head for several
days, water can even become blocked from passing through the shower plate.
To prevent these problems, perform the following cleaning procedures daily:
Place the cleaning membrane in the lter basket (without detergent).
Insert the portalter in the group head, but do not tighten fully (the portalter should be loose).
Press the Continuous Dispensing button for Control machines, or press the brew button
for Pulser machines. For Leva machines, raise the brewing lever for 15 seconds.
Make an opening-closing movement of the portalter in place without closing it. Water will now
ow around the portalter, owing through the closing surface and cleaning it.

WARNING!
Take special care to avoid scalding when
performing this cleaning operation, as the hot
water used to clean the gasket will spill over
the sides of the portalter.
WARNING!
Do not fully tighten the portalter. If fully
tightened, high-pressure water may spray out
and cause scalding or serious injury.
Remove the portalter from the group head.
Clean the shower plate and group gasket with a soft brush to remove any coffee residue.
