Warning!
Finishing the back flush routine without cleaning powder is essential to prevent remnants of cleaning
powder settling between the plunger and housing of the solenoid valves.
Clean program
Maximum water-pressure during the clean program will be incoming pressure and thus not as high as
when you perform the back-flush manually and may thus not be as effective.
The groups will simultaneously pressurise for 15 seconds (with pump active when installed) 8 times in
a row with a pause of 9 seconds in between. The LEDs on the flush/relief unit will flash during the
cleaning program, the digit displays continue to show the temperature.
Procedure
1. Remove the filter holders, flush all groups (with handle).
2. Clean the group screen and group seal with the plastic group brush.
3. Pry the filter baskets (e.g. with the group screen extractor) from the filter holders (see
Figure 21 )
and replace them with blind filters.
4. Scoop 1 teaspoon of coffee dissolving powder in each blind filter and lock the filter holders in the
groups.
5. On the touch screen, start the cleaning program (the LEDs on the units start to flash).
6. One-by-one pull the brew-levers into locking position (the LEDs remain flashing).
While 7 (and 10) is in progress, clean the filter baskets.
7. After 8 pressurising cycles the LEDs stop flashing, the program has ended.
8. Unlock the levers, relief pressure (with handles).
9. Unlock the portafilters and clean them under running water, replace in groups.
10. Start the cleaning program without cleaning powder again to remove all cleaning powder from the
groups.
11. Pull levers into locking position, wait until the LEDs stop flashing (the program has ended).
12. Unlock levers and return to resting position (relief).
13. Replace blind-filters with filter baskets.
Note! The entire procedure using the clean program will take 7-10 minutes.
