Keurig Coffee Makers Not Brewing (Won't Dispense Water): How to Fix It Yourself

A Keurig that won't brew is almost always clogged. Calcium buildup from hard water blocks the internal water lines, and coffee grounds clog the entrance and exit needles. A thorough descale and needle cleaning fixes this about 90% of the time.

⚠️ Safety First

  • The water inside a Keurig gets very hot — don't open the K-Cup holder immediately after a failed brew attempt.
  • Unplug the machine before cleaning the needle.

Step-by-Step Repair

  1. Step 1 of 5
    1

    Clean the exit needle

    Open the K-Cup holder and look at the bottom of the lid — you'll see a sharp needle with two small holes. This is where water enters the K-Cup. Use a paper clip to poke out any grounds clogging those holes. This is the most common fix.

  2. Step 2 of 5
    2

    Clean the entrance needle

    Remove the K-Cup holder assembly (it pulls straight out). On the bottom, there's another needle. Clear it with a paper clip as well. Rinse the entire holder assembly under warm water.

  3. Step 3 of 5

    Descale the machine

    Fill the reservoir with equal parts white vinegar and water (or use Keurig descaling solution). Run brew cycles with no K-Cup until the reservoir is empty. This flushes calcium deposits from the internal water lines.

  4. Step 4 of 5

    Rinse with clean water

    Refill the reservoir with fresh water and run at least 3-4 brew cycles to flush out all the vinegar. Nobody wants vinegar-flavored coffee.

  5. Step 5 of 5

    Burp the machine (if still not working)

    If it still won't brew, there may be an air lock. Turn the machine upside down over the sink and pat the bottom a few times. This sounds ridiculous but it dislodges air bubbles trapped in the water line. Flip it back over, fill the reservoir, and try again.

If That Didn't Work

  • The water reservoir may not be seated properly — remove it and snap it back firmly.
  • The internal water pump can fail on older machines (you'll hear nothing when it tries to brew).
  • The magnet on the reservoir that tells the machine it has water may be displaced. Check that the reservoir seats flush.

When to Call a Professional

Keurig machines are generally not worth professional repair. If descaling and needle cleaning don't fix it, a new Keurig costs $60-150. Keurig offers a 1-year warranty — contact them for a potential replacement. Descale every 3 months to prevent future clogs.
