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.

MAX level with warm water.

What To Do
Ensure all three tabs of the Portafilter
are fully inserted into the Group
Head, and rotated to the center
position. See Operating Guide
Section, page 8.
Change to a coarser grind.
Tamp the grinds more lightly.
Clean around the top edge of the filter
and wipe the Group Head clean.
Wipe with a damp cloth. Clean the
seal including the bayonet corner
areas with a brush to remove grinds.
Contact Calphalon Customer Care.
Details are on the back cover page.
Fill reservoir with water. Run water
through the machine without a Filter
Basket to ensure it is fully primed.
See Descaling Section, pages 26-27.
Use the Cleaning Pin to unblock the
Filter Basket.
Empty the Filter Basket and rinse
under water to clean. Wipe the group

Refill the filter with grinds and tamp.
Change to a coarser grind.
Tamp the grinds more lightly.
See Descaling Section, pages 26-27.
Use fresh beans and grinds.

an airtight container.
Tamp more firmly.
Use a finer grind coffee.
Ensure coffee is tamped evenly and
check there is nothing obstructing the
pouring spouts.
Keep Portafilter in Group Head until
milk frothing is finished. This will give
more time for the water to dissipate.
Try different brands of coffee.

thermoblock to purge steam and cool
down before pouring a shot of espres-
