Auto Backush Connued...
If you have used soap or another cleanser during the backush, run the backush process a second me with
no soap or chemicals to rinse the internal tubing and brew valve. Failure to rinse aer a soap backush can
leave soap residue in the brew valve aecng taste and/or machine behavior.
Any number of brew groups can use the auto backush feature at the same me. The auto backush can be
interrupted mid-cycle by moving the brew head to either side, pressing the purge buon, or by turning the
seng on the controller back to “o”.
To cycle back to the temperature overview screen, press the down buon.
