How do I clean the entrance and exit needles to remove coffee grounds?

To clean the exit needle, remove the pod holder assembly, detach the funnel, and insert a straightened paper clip into the exit needle to loosen any coffee grounds. For the entrance needle, lift the handle and carefully insert a straightened paper clip into both holes on the underside of the lid, then lower the handle and run two water-only brew cycles without a K-Cup pod.
