Check the Water Reservoir
- Ensure the water reservoir is properly seated in its position.
- Fill the reservoir with fresh, cold water to the MAX line.
- Secure the reservoir back into place, making sure it clicks in.
Perform a Descaling Cycle
- Fill the water reservoir with a descaling solution or white vinegar mixed with water (1:1 ratio).
- Place a large mug on the drip tray to collect liquid.
- Run a brew cycle without a K-Cup, allowing the descaling solution to flow through.
- Repeat until the reservoir is empty.
- Rinse the reservoir thoroughly and run 2-3 plain water cycles to flush out any residue.
Check for Clogs or Blockages
- Remove the K-Cup holder and clean it thoroughly with warm, soapy water.
- Use a paperclip or similar tool to clear any debris or coffee grounds in the needle or brew pathway.
- Inspect the exit needle for blockages and carefully clear if needed.
Reset and Test the Brewer
- Unplug the Keurig for 30 seconds, then plug it back in to reset.
- Fill the reservoir and run a brew cycle with plain water to test performance.
- Repeat if necessary until the full 6-12 oz is brewed properly.
Tips and Warnings
- Always use fresh, cold water for each brew to avoid mineral buildup.
- Descale your machine every 3-6 months, depending on water hardness and usage.
- Never force open the machine or use sharp objects to clear clogs.
- Follow manufacturer’s instructions for cleaning to prevent damage.
