Maintenance Guide: Backflushing & Deep Cleaning
Follow these steps to ensure your espresso machine and components stay in top condition:
- Preparation: Remove the filter baskets from the portafilters.
- Disassembly: Use a screwdriver to remove the screws from the group head shower screens. Place the screws in an espresso cup for safekeeping.
- Initial Rinse: Rinse the baskets, screws, and portafilters under running water to remove any visible coffee residue.
- Soak: Place the baskets and screws in a bath of hot water mixed with Cafetto cleaner. Let them soak for at least 5 minutes.
- Scrub Group Head: While the parts are soaking, use a group brush to thoroughly scrub the group head area.
- Blind Basket: Place the blank (blind) basket into the portafilter.
- Add Cleaner: Add a very small amount of Cafetto to the blank basket, then lock the portafilter into the machine.
- Auto Backflush: Activate the automatic backflush cycle. Press and hold the top and left buttons for 4 seconds (or until you hear it click on). The cycle will pulse 10 times.
- Water Rinse: Remove the portafilter to dump out any leftover cleaner. Lock it back in and run the backflush cycle once more using only water.
- Final Rinse: Remove the shower screens and baskets from the Cafetto bath and rinse them thoroughly with clean water.
- Reassemble Screens: Screw the shower screens back into the group head. Note: They should be “finger tight”—do not over-tighten them.
- Finish: Replace the baskets into the portafilters. Your machine is now clean and ready for use!
