How do I perform a cleansing rinse for both the single cup and carafe modes?

For a cleansing rinse in single cup mode, press the OZ button once to power on and then press the 8 oz button without inserting a K-Cup. For carafe mode, press the CUPS button to select your desired brew size (without filling filter basket with coffee), or use the 8 button if no specific size is needed. Perform this process whenever the brewer needs cleaning. (Pages 2 and 3)
