Oster single-serve coffee maker does not puncture or pierce the coffee pod properly, causing no or slow flow.

Safety first: Unplug the coffee maker and allow it to cool. Be careful of sharp needles.

Clean piercing needles:

• Open the pod compartment and locate the upper and lower piercing needles.
• Use a straightened paper clip or the cleaning tool provided by Oster to gently clear any coffee grounds from the needle holes.
• Rinse the pod holder under warm water to remove residue.

Inspect alignment:

• Ensure the pod holder is seated correctly and not warped.

If needles are bent or damaged, replace the pod holder / piercing assembly.
