Shower Screen and Water Jet Breaker and Brew group
The shower screen and Water Jet Breaker are located in the brew group and are held in
place with one screw. The Water Jet Breaker is behind the shower screen and it is
designed to help the shower screen distribute the water over the coffee evenly. When you
remove the shower screen the Water Jet Breaker will fall right out exposing the brew
group. The brew group is the area behind the shower screen, it is permanently attached to
the machine and cannot be removed for cleaning. The shower screen comes in direct
contact with the coffee and due to the design of the Silvia coffee can actually be forced
up into the shower screen, water jet breaker and brew group. The screen has very small
holes that can become plugged over time
Shower screen
There are two cleaning procedures that can be done to clean out the shower screen. You
can remove it for cleaning and you can rinse it while it is still in place. The more often
you rinse it while it is in place the less often you will have to remove it for a thoroughly
cleaning and the better your coffee will taste. It is easy to do a quick rinse, it only takes a
few seconds and it can do after each shot of espresso.
Quick Rinse
After you complete your shot immediately remove the portafilter from the
machine and turn on the brew switch for a couple of seconds. The pump will run
water through the shower screen and will remove most of the used coffee.
Thorough Cleaning of the Shower Screen, Water Jet Breaker and Brew group.
For a thorough cleaning you will have to remove the shower screen and water jet breaker
from the brew group and soak them in a cleaning solution. Use a commercially available
espresso machine cleaner such as the product called “Espresso Machine Cleaner” by
Urnex. Follow the manufacturer’s instructions for preparing your cleaning solution.
First remove the one screw that holds the shower screen and water jet breaker in place.
The only tool you will need is short flat bladed screwdriver with a wide tip. A small tip
may cause the screw to strip. After both parts removed from the machine you may clean
the area behind the shower screen with some of the cleaning solution and a brush. Hold
the shower screen up to the light and you will be able to see how plugged up it has
become. Keep track of how plugged it is and how long it is has been between cleanings
to help you plan out a maintenance schedule. Now soak the parts in your cleaning
solution, brush them and rinse them thoroughly before installing them back into the
machine. You will have to judge how long to soak it and how many times you will have
to brush it by how plugged it has become. If you clean it frequently it may only take few
minutes if it has been a long time in-between cleanings it may take longer and need
multiple brushings and rinsing. Make sure all parts are rinsed thoroughly before you
install them back into the machine. Do not over tighten the screw that holds the shower
screen in place or it may be difficult to remove the next time.
