Step 2: Clean the Needle and Brew Area
- Turn off and unplug the machine.
- Lift the brew head and carefully insert a paperclip or needle cleaning tool into the needle to remove any coffee grounds or debris.
- Wipe the area with a damp cloth to remove residue.
Step 3: Check Water Reservoir and Connections
Ensure the water reservoir is properly seated and filled with fresh water. Remove and clean the reservoir if necessary, and verify there’s no blockage in the water inlet.
