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 lter basket from the portalter and t the back ush
cap.
2. While the brew water is owing loosely insert the portalter into
the group head, rotating the portalter back and forth. Keep
emptying the blind basket of hot water and old grounds until the
water runs clear.
3. You should backush the group head every day.
GROUP BREW HEAD
1. Every week, after backushing, add a small amount of espresso
cleaning detergent to the blind basket. Dissolve the detergent
in hot water and insert the portalter into the group head. Use a
solution readily available at your local store.
2. Turn the group paddle on and off again after about 10 seconds.
Repeat this several times.
3. Empty the basket of the detergent and backush using water
only as above until the group is thoroughly cleansed of detergent
residue.
REMOVING THE SHOWER FOIL AND HEAD SEAL
1. Using a number 3 allen key remove the shower foil and
dispersion screen.
2. Scrub the inside of the group head with the supplied group
cleaning brush.
3. Using a damp cloth wipe clean the area where the portalter
engages into the group head.
4. 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.
5. The head seal is a standard 8MM and may need to be replaced
from time to time.
PORTAFILTER
1. Remove the lter basket from the portalter handle using a small
screwdriver or the under-side of the blind basket.
2. Wipe the inside of the basket and portalter clean with a damp
cloth.
3. If the coffee oils have built up soak the metal end of the
portalter and basket in the same detergent solution as the
shower foil and brass spreader above.
4. Rinse thoroughly, dry and return.
