I just descaled my machine and have done the paperclip clean out (top and bottom), but my machine is not clearing out with the burst of air after a brew. It is more like a gurgle, and it is driping after a brew which it has never done before.

There are pins that pokes holes on top and bottom of coffee kcups, find the pins and clean it by unclogging with paperclips or some thinner wire.

Important discovery I wanted to share.

My B31 Kuerig worked great for over a year, then suddenly seemed unable to spit out any coffee or even water when no coffee pack was loaded. Descaling did nothing to fix ... only a drop or two of water (or vinegar) could flow out the machine.

I was able to fix it by clearing grounds stuck in the holes of the TOP needle, NOT the needle opening in the funnel for the bottom of the cups.

The instruction manual for the B31 does not tell you to clean the top needle ... it just says how to clean the funnel and the bottom (exit) needle ... but the Kuerig video on YouTube does explain where to find the top needle and how to clear it of a jam from corrosion or coffee grounds.

Be careful ... the top needle is sharp, and it is hard to spot the tiny slots in it.


Using a paperclip, I was able to push up and clear some grounds that were blacking water from flowing freely. These grounds then came out with my next cycle of water.


To see the upper needle, look up into the top of the machine after you open it. There are also two screws you can take out to see the top tube of water flow down to the coffee cup. That is where I was able to spot some grounds that came lose after I used a paperclip to clear.

I was ready to trash my machine ... now it is good as new. Good luck!

I cant help you but I am having the same problem..I have to turn my machine off to get the brewing light off...

Hi, I think I can help you fix this problem. First off, check the needles that puncture the cups and get them cleaned off with a paperclip or a toothpick. Try to clean them with a small brush or a even a toothbrush with a little vinegar. Clean the top and bottom and be careful because they're sharp. Then, run a full resevoir of white vinegar through your machine. Then, let it sit with "ADD WATER" for a few hours. Lastly, rinse with clear water, a full resevoir so you get rid of the vinegar smell and taste.

1. Power off machine.

2. Using a metal paperclip, insert it into left side of top needle. It must insert at least 1" deep. Insert it into slot on right side and again from back of needle.

3. Remove KCup cradle. Separate bottom from top. In the top section, insert the paperclip up into bottom needle from the bottom upwards. It will not go all the way thru and this is normal.

4. Reassemble KCup cradle and reinsert it back into coffee maker.

5. Power on machine.

6. Brew a cup of water only. There may be coffee grounds in the water and these should eventually clear during the remaining steps. NOTE: A large cup brew cycle should output a full 8 ounces (235cc). Less means there is still a blockage

7. Empty reservoir and fill with undiluted distilled white vinegar. Repeatedly run brewing cycle until Add Water light comes on.

8. Make sure Auto-OFF is NOT set and let last cycle of vinegar remain inside machine for 4 hours.

9. Refill reservoir with fresh water and repeatedly run brewing cycle until the water is clear and odorless.

10. Set Auto-OFF, if preferred.

If you have cleared the end of the wand with a paperclip then it is possible that the steam boiler is damaged or the thermostat on the boiler is damaged.
