REMOVING THE SHOWER FOIL AND HEAD SEAL
1. Use the rounded end of a 12mm ring spanner to lever out the
shower foil and head seal.
2. Unscrew the brass spreader inside the group using a short blade
screwdriver.
3. Scrub the inside of the group head with the supplied group
cleaning brush.
4. Using a damp cloth wipe clean the area where the portafilter
engages into the group head.
5. Soak the metal parts that have been removed (shower foil, brass
spreader) in a solution made from 2 teaspoons of espresso
cleaning detergent and hot water. Soak for 10 minutes. Rinse
thoroughly, wipe clean and return.
6. Use the portafilter to refit the shower foil, which sits on top of the
head seal, into the group head. The chamfer on the seal should
face up.
7. When the head seal becomes brittle or the shower foil gets
punctured, they will need to be replaced. These items are
consumables. Contact your authorized Rocket Espresso dealer.
PORTAFILTER
1. Remove the filter basket from the portafilter handle using a small
screwdriver or the under-side of the blind basket.
2. Wipe the inside of the basket and portafilter clean with a damp
cloth.
3. If the coffee oils have built up soak the metal end of the
portafilter and basket in the same detergent solution as the
shower foil and brass spreader above.
4. Rinse thoroughly, dry and return.
PREVENTATIVE MAINTENANCE
& CLEANING
Keeping your machine clean will prolong its life and produce much
better espresso beverages.
STEAM NOZZLES
1. Clean the steam nozzle after every use by wiping with a damp
cloth. Turn the steam wand on to release condensation and milk
residue.
2. If the steam jets get blocked with dry milk use a paper clip to
unclog them.
BACKFLUSHING
1. Remove the filter basket from the portafilter and fit the back
flush cap.
2. While the brew water is flowing loosely insert the portafilter into
the group head, rotating the portafilter back and forth. Keep
emptying the blind basket of hot water and old grounds until the
water runs clear.
3. You should backflush the group head every day.
GROUP BREW HEAD
1. Every week, after backflushing, add a small amount of espresso
cleaning detergent to the blind basket. Dissolve the detergent
in hot water and insert the portafilter into the group head. Use a
solution readily available at your local store.
2. Turn the brew lever on and off again after about 10 seconds.
Repeat this several times.
3. Empty the basket of the detergent and backflush using water
only as above until the group is thoroughly cleansed of detergent
residue.
