Page 8: Operation
1. The use of a damp cloth rinsed in any mild, non-abrasive, liquid detergent is recommended for cleaning all surfaces on Bunn-O-Matic equipment. 2. Clean the gasket that seals the filter & group head, located under the group head. Ground coffee build- up on this gasket will result in a bad seal of the filter holder, and will leak brewed coffee onto the outside of the filter holder when brewing. - Page 9 BUNN Espress® Milk Frother NOTE- The milk frother parts need to be cleaned as described below at least every four to six hours depending upon use. See the DBC instruction manual for changing the clean warning alarm. It is factory set at 25 drinks.
