REGULAR
MAINTENANCE
If you need to take your E61 group apart to
lubricate it or replace a part, here is an excellent
exploded view of all of its parts, how it comes
apart and how it goes back together.
Regular backflushing is a vital part of any ma-
chine’s maintenance schedule. Not only will it
prolong the life of your machine, but it will also
prevent the buildup of rancid coffee oils that will
make your espresso taste bitter and acrid.
In the sixty years since Ernesto Valente had the
idea for this groundbreaking design, the E61
group head and it’s features have become
ubiquitous on espresso machines the world over.
As tough as it is, it still has a number of moving
parts that can wear down over time.
