Before you begin troubleshooting your machine, unplug it and make sure it is cooled. Now remove the needle holder by turning it counterclockwise.
Both the back and the front of the needle have holes in them. Use a straightened paper clip to gently push any coffee grinds from the holes in the needle before rinsing the needle under cool water. Return the needle holder to the machine and turn it clockwise to lock it in place.
Finally, brew 2-3 cups of plain water to finish unclogging and rinsing your machine.
