Under the cover there is a seal that should
be changed annually, in fact, like all seals, it
may deteriorate in time and lose elasticity.
WHEN TO REPLACE IT
The seal must be replaced annually or
when there is a leak from the pre-infusion
chamber.
HOW TO REPLACE

el and the group cover, as explained in
