First, turn the coffee machine off or unplug, remove the pod holder, and start cleaning. The exit needle is inside the pod holder, so exercise caution when handling it.
Carefully pull the funnel attachment from the pod holder — an exposed tube should be on the underside. Straighten one edge of a paperclip and use it to clear any debris.
The entrance needle is visible after lifting the lid. Place the paperclip into the side holes of the needle and carefully move the paperclip around until the debris is cleared.
Place the pod holder with the funnel securely re-attached back into the machine. Lift and lower the handle before running two water-only cycles using the largest cup size.
