Daily
Body
Parts and tools:
•
Soft, clean towel
•
Non-abrasive cleaner, e.g. window cleaner (optional)
Procedure:
Use a soft, clean towel to wipe the surfaces of the machine. Do not use
abrasive cleaners. Small amounts of window cleaner may be used on the
stainless steel components. If your Slayer has wood panels, please refer
to the “Wood Care” section.
Groupheads
Cleaning and backflushing the groupheads prevents the build up of coffee
oils. Backflush each group at least twice daily: once with water and once with
an approved espresso machine cleaning powder.
To maximize efficiency and lengthen the life of wearable parts, we
recommend keeping two (2) sets of dispersion screens and screws on hand.
Alternate between sets for each end-of-day backflush (see below).
General Group Cleaning
Recommended as part of every backflush cycle, or as needed
Parts and tools:
•
Cleaning brush or towel
•
Flat-head screwdriver
•
Portafilter with basket removed
Procedure:
1. Begin with one grouphead: use a cleaning brush or towel to scrub the
portafilter gasket and loosen oil and coffee grounds.
2. Remove the dispersion screw and screen with a flat-head screwdriver
and rinse with clean water.
‣
Ensure that the dispersion screw holes remain clear of coffee
grounds, as they may otherwise damage internal parts of the
grouphead.
3. Use a clean, damp towel to wipe oil and grounds from the face and
sides of the dispersion block, as well as the portafilter body.
4. Return the clean dispersion screw and screen to the grouphead.
5. Thoroughly rinse portafilter with hot water, insert basket, and lock in
grouphead.
‣
CAUTION: failure to reinstall the dispersion screw and screen
before next use may cause the grouphead to clog with coffee
particles. Do not attempt to brew espresso before the dispersion
screw and screen have been correctly installed.
