DESCALING: GROUP HEAD
AND STEAM WAND
After continued use, your machine may develop a build up of mineral deposits and will require
occasional descaling. We recommend descaling your machine every 4-6 months, although this
period will depend on the hardness of water and frequency of use.
Important: Your machine will let you know when it’s time to descale. The ON/OFF, 1 CUP, 2
CUP and STEAM buttons will flash 5 times. You will need to descale your machine and reset it
to cancel the descale warning.
