Check and Refill the Water Reservoir
- Ensure the water reservoir is filled to the appropriate level with fresh water.
- Remove the reservoir and rinse it if it appears dirty or has mineral deposits.
- Replace the reservoir securely back into the machine, making sure it clicks into place.
Clean the Brew Needle
- Turn off and unplug the machine for safety.
- Remove the water reservoir and drip tray.
- Use a paperclip or the cleaning tool that came with the brewer to gently clear any clogs in the needle.
- Run a water-only brew cycle to flush out residue.
Descale Your Keurig
- Mix descaling solution with water according to the product instructions.
- Fill the water reservoir with the solution.
- Run a brew cycle without a K-Cup, allowing the descaling solution to clean internal deposits.
- Follow up with multiple water-only brews to rinse out any remaining solution.
Check Brew Size Settings
Verify that you’ve selected the correct brew size on your control panel. For full cups, choose 8oz or larger, if available. Adjust if necessary and test brew again.
Use a Reusable Filter for Ground Coffee
If you brew with ground coffee, ensure you’re using a compatible reusable filter like the My K-Cup® Reusable Coffee Filter. Proper use prevents clogging and ensures full cups.
