What to do
Keep using. This Seal will bed in during the first
few uses and become easier to turn.
Fill with less coffee grinds.
Ensure all three tabs of the Portafilter are fully
inserted into the Group Head and rotated to the
centre position.
Ensure a Filter Basket is inserted into the
Portafilter before using in the Group Head.
Change grinder to a coarser Grind Setting.
Fill with less coffee grinds.
Apply less force during tamping.
Wipe around top edge of the Filter Basket before
inserting into Group Head. See Coffee Making
Guide.
Clean the parts with the Cleaning Brush and
damp cloth.
Contact Oster Customer Care.
Store coffee beans in a dry, airtight container.
Place in a cool dark cupboard.
Use the default 92°C extraction temperature. See
Customisable - Extraction Temperature.
Pour hot water from the Hot Water Tap into the
cup before extracting espresso.
Hold the Portafilter under the Group Head and
press the ONE CUP BUTTON. Allow water to
run through.
