Step 1: Ensure Proper Water Level and Placement

  1. Open the water reservoir lid and refill with fresh, clean water if low.
  2. Make sure the reservoir is securely seated in its position.
  3. Confirm the water level is within the recommended range for your brew size.

Step 2: Clean the Water Needle and Brew Path

  • Turn off and unplug your Keurig for safety.
  • Use a paperclip or a needle to gently clear any clogs in the needle located at the top of the machine.
  • Wipe down the needle area with a damp cloth to remove any residue.

Step 3: Descale Your Keurig

  1. Fill the water reservoir with equal parts water and descaling solution or white vinegar.
  2. Run a brewing cycle without a K-Cup, allowing the solution to pass through.
  3. Repeat with fresh water to rinse out the descaling solution.

Step 4: Check for Blockages and Clogs

Inspect the brew head and needle for any grounds or debris. Use a toothpick or a small brush to dislodge any blockages. This can significantly improve water flow and brewing performance.

Step 5: Use Reusable Filter or Proper Pods

If using ground coffee, switch to a compatible reusable filter like the My K-Cup® Reusable Coffee Filter to prevent clogging and ensure full brewing capacity.
