Step 2: Automated Cleaning Backflush
Tech Tip! Only backflush one group at a time! Cleaning product foams during the backflushing process and drains at a slower rate.
Starting at Group 1...
... and repeating for Groups 2, 3, and 4 (if applicable) once Steps 2 & 3 have been completed.
Scoop a teaspoon of espresso cleaning product into the blank portafilter.
A scoops worth of the spoon on the reverse side of the grouphead cleaning brush is sufficient.
Pour a small amount of hot water into blank portafilter, along with the cleaning product, and allow to effervesce.
Approximately 30 seconds.
Engage blank portafilter into grouphead.

If necessary, press any button to manually cancel cleaning cycle.
Step 3: Rinse (No Espresso Cleaning Product)
After Automated Cleaning backflush has been completed.
Press Button 1 (Single Dose) to allow clear water to dispense from grouphead.
Rinse blank portafilter so it is free of any residual cleaning product.
Re-engage blank portafilter into grouphead and activate Automated Cleaning function once more...
... However this time, manually cancel cleaning cyle after the second 10 second interval.
Repeat Steps 2 & 3 for remaining Groups!
Rinsing the group with clear water after a cleaning cycle ensures the grouphead is clean of residual espresso cleaner!
