How do I descale the K-Express Essentials coffee maker?

Pour the entire bottle of Keurig Descaling Solution into an empty reservoir, then fill the empty bottle with water and add that too. With the coffee maker plugged in and powered off, press and hold the 6 oz and 10 oz buttons together for 3 seconds to activate Descale Mode, then press the 8 oz button to begin brewing. Continue brewing 8 oz until the ADD WATER light illuminates, then empty the reservoir, refill to MAX with fresh water, and continue rinsing until the DESCALE notification turns off. (Page 5)
