The 920 is a good machine. Good coffee.

When you go to descale it, when you search for info, make sure you’re aware of what generation software your machine has. I didn’t know there were different generations, and ours is a 3rd generation machine. The descaling process is different for each generation and the initial instructions I got from the web didn’t identify they were for a specific generation. I suspect the product manual that you get on a search is for a first generation machine. Descaling is tricky and it seems to cause many people angst.

Final word on descaling - to get rid of the “descale me” indicator - hold down 1 cup button, then press power to get to advance menu and landing on “rset”. Then press menu to get to “hrd3”. Press menu. Machine will then heat up and descale indicator will be gone.
