Also check the filter in the water reserve. I tried all the above with no luck. I then removed the three screws inside the water tank, took out the metal mesh filter, and tried to run the system. Worked perfectly. I then tested the filter by putting water on it, and it was almost water proof.

I am currently serving in Afghanistan and our Keuring B130 quit working a few days ago. We had to go back to the old fashioned coffeemaker, which was very painful. I was waiting on my wife to send some Keurig Cleaner from the states, when I got desperate and decided to research it on the web. I found your site, used the paper clip trick, and ran two cups of straight vinegar through it and it works like a champ again. The Taliban can sleep easier knowing that we're no longer Keurig-deprived of our caffeine fix. Thanks for the very informative site! Happy Holidays to all from Afghanistan!

Take the top cover off the brew area removing the two silver screws under the lid where the k-cup is located

Removed the zip tie leading to the water filter.

Lifted the black ring that holds the hose that goes to the needle and pull the hose up

Blew back down that line and lots of sediment will come out from behind the filter

Turn the unit on and let it brew hot water into the holding tank just so you can see if it is cleared

Replaced everything to its original position including putting a new zip tie

on the line you removed.

This is the third Keurig I have fixed that has had the same problem.

Generally, you have to de-scale the Keurig every three months

You don't have to use a whole tank of vinegar.

Put a 50/50 mix of vinegar and filtered water in the tank, run it once

Let the brewer sit for 45 mins so the vinegar can act on the scale

Run it a second time and let it sit for 15.

Then empty the tank, washing it throughly or you will get slime that builds up on the side and at the inlet at the bottom of the tank.

Now run the clean water through the Keurig for a few passes until you no longer smell vinegar.

I took the two screws off under the lid opened it up and discovered one of the pump hoses came off. I put it back on and it was good as new. It was easy to get the lid off. Just Need a small Phillips head screwdriver and a flashlight to see.

I was in the same boat.. half cup brewing. I used paper clips (very helpful) I read to put the whole machine in the sink and use your pressure hose over the water reservoir for 30 seconds to flush the system which im sure helped clean the lines but caused the water to not siphon. I was one step away from either tearing it apart or throwing it in the garbage when I tipped the whole machine upside down and shook it. IT WORKS PERFECTLY NOW! coincidence? no clue but hey, it works. figured I'd share for all those who are at wits end like I was.

Ok...Mine had similar issues. After trying all of these I was still unable to get water to flow. So, I took the head apart. I then removed the hose from the nozzle that is in the head. I started to brewer, carefully holding the hose in a cup. I got some water flow, but not much. I then took the nozzle out of the head and blew through it. Apparently it is a pressure sensitive nozzle and it may have been stuck as I was able to clear it out. I ran the cycle through the brewer several more time before I was able to get good flow through the hose. I then hooked it back up to the nozzle and it works. I just made a fresh pot...good to have you back Keurig.

Be careful with the hose when brewing as the water is very hot.

The burping method may have had the most impact as I would have the machine on and tilt it upside down (water reservoir removed) and I could get some flow.

I had this problem with my single cup unit after it had sat unused for three months. Tried the paper clip, no luck. Then I found a post elsewhere that said that if the pump dries out, it can't re- prime itself. I took a turkey injector without the needle, filled it with water and placed it over the hole in the bottom of the reservoir and gave it a strong blast of water until water came out where the coffee normally does. That did the trick.

To help avoid future need to unclog the spout, I have always pressed down on the kcup with my fingers after inserting it in the holder. What this does is it releases the vacuum downward. If you don't do that and close the lid, the coffee or whatever is in your kcup, shoots upward. Then when water hits it, some comes out but some will stay and clog it.

It's been mentioned on this list before but I think the procedure for installing the K-cup is very important. For various reasons K-cups often have pressure built up inside. When the top of the K-cup is pierced, when lowering the lid, the pressure blows unbrewed coffee into the upper needles which can cause a clog. I think it's better to first use your two thumbs to press the K-cup firmly down into the cavity which pierces the bottom and relieves the pressure . That way coffee grounds won't blow up into the upper needles when the head is lowered. As always, good luck and your mileage may vary.

Use compressed air and back-blow from spike that punctures the K-cup. Then remove water reservoir and blow compressed air through there too. After 4 + years, this was the ONLY fix that worked to dislodge particles in tubing system. Took all of one minute and saved $$$ buying a new unit.

Had the same issue with a clog. I had to remove the two screws under the cover and clean out the hose it's self. Once I completed it ran like new!!! Tried the paper clip but the clog was too much.

Most of the problems are caused by minerals in the water. Take the tank off and see if there is a strainer (if there is back blow with compressed air, you may have to remove it ..3 screws...I did) reinstall and check that water flows freely when valve depressed. Go to store and purchase DISTILLED WATER in gallon jugs (not spring water)...about a dollar a gallon...use this only...My problems were ...add water light on when full...brewing a half of a cup...descale light on...you may want to descale it at the same time...Mine has been working great for about six months...

I found the metal screen mesh in the bottom of the water reservoir was starting to plug up with lint after 2 years of use. It was impossible to see until I removed the 3 screws holding it down, and took it out. Washed it with water and it fixed the problem.

Follow up to "Mark" Our cups seem to be under pressure, not vacuum, possibly due to altitude (over 5k ft). I push them down so the needle punctures the bottom, then repeat after turning the cup until there are 6-8 holes in the bottom. Also have better luck with the plastic k-cup you fill yourself. Before this my brand new machine was clogging and short cycling starting with the second cup!

I placed the kcup pod in the holder,and closed the lid so the pod would get punctured both top and bottom.

Without going to the next step, I lifted the lid up and removed the pod to see if it was getting punctured.

Well, it was not. The top was fine but not the bottom, which was barely punctured.

So I got a pointy knife (pointy nail works too) and made the hole a tiny bit bigger.

The water can now go thru the pod easier.

This happens on those pods that look like they are overpacked.

The air pressure inside the pods forces the coffee grinds into the water line and clogs up the pins.

I hope I'm naming the parts right and that this fixit is understandable.

i took the bottom plate off of mine looked at hoses..didnt really see anything wrong with it so i i plugged it back in while it was laying on its side so if there was something coming out where the water tank is it would pour out in the sink and bam water started coming out on its own...unplugged it then put all the screws back in the bottom set it back up and plugged it in. turned it back on and it was working like new..ran thru the steps of running vinger through it and its working like new

After moving mine would not prime, I tried all of the tricks you find on here I was ready to give up. I took the top where the k cup goes in and I pulled the hose off of the one way valve, I then took a meat injector syringe and put it in the hose while blocking the over flow back into the water tank with my thumb I pulled and pushed water thru the the hose until i got hat water coming out of the hose. this will push water into the tank and prime the pump.

it now works just fine.

I took air hose and connected to rubber safety hose inside water resovoiur and blew out . Took 1 second. Dw

I have the Breville version, three+ years old. It's a replacement Sur La Table gave me, no questioned asked, when the first one short-cupped after only a month. (I'd owned a Keurig B75 Platinum that had failed twice and been replaced twice by Keurig--and broke again a week past warranty expiration). I use Crystal Geyser water, and sometimes filtered water from the fridge. After it short-cupped sporadically, I descaled 6 mos. ago, which worked for awhile. In the past couple of weeks, not only did it start short-cupping drastically but also took forever to heat and brew. Got so that I had to use my espresso machine to add either hot water or brew a shot of espresso into the black coffee in the cup!

Did the paper-clip thing on the needles and cleaned the reservoir screens--then it heated a full cup of hot water (slooowly) but only a half-cup of tea. Removed reservoir again to unscrew the top in order to check the hoses (housing the My K-Cup holder and scoop) but found and removed only two screws. And the top would not budge, so I put the screws back in. Next, I removed the reservoir again and hit EVERYTHING that had a hole in it with a blast of canned air. Then I dragged the machine to the sink, turned it upside down and shook and whomped it on the bottom a couple of times. Brought it back, replaced the reservoir, plugged it in and turned it on. Had to reprogram it--and this time it brewed a full 7-oz. cup of Sumatra (as swiftly as when new) on the default 7-oz. setting. Keeping fingers crossed. Next time if it malfunctions I will do all of the above plus descale. If that doesn't work, I will let it rest in peace--at its age it's already beaten the Reaper. Would replace it with a Vue were it not for the huge backlog of K-cups I still have (several months' supply, at an average of six or seven cups a day). But meanwhile, I've developed a taste for a "red-eye" (that shot of 'spro brewed into a cup of coffee). ;-)

Here's what I did to solve the problem. You'll need a small screw driver, two small ty-wraps, a paperclip, and vinegar and water. Here's the process:

1. Descale the brew machine using the instructions from Kuerig

2. Clean out the exit needles using a paper clip per the Kuerig instructions

3. Clean the one-way valve. This valve is located inside the unit beneath the top cover of the unit. It will gum up and inhibit the flow of water through the unit. Cleaning/blowing it out will fix this issue.

a. Unplug the unit.

b. Remove the water container from the unit.

c. Remove the top cover from the unit. This requires removing the two small screws from

the bottom of the top cover. Open the top as you would to put in a k-cup. The two

small screws are located on the top. You'll need a flashlight to see them.

d. The one-way valve is located on the top and is a larger clear rubber valve attached to

the inlet needle on one end and the hose to the heater on the other end. This end is

secured with two small ty-warps. Remove the two small screws holding the valve in

place. Cut the ty-wraps and remove the valve from the inlet needle and hose.

e. Take the one-way valve and blow it out from the end that was hooked to the

heater hose. I used a small air compressor to clear the valve. You'll see the check

valve move open and closed on the inside while blowing it out.

4. Replace the one-way valve.

5. Replace the cover. This can be a pain since it's hard to see the holes and screws. Be prepared for a few cuss words. If you drop the screws into the k-cup holder you can shake it and they will fall out the bottom.

6. Replace the water container.

7. Plug the brewer in and test.

Now you can run a cup or two through the system. Again I used a small compressor to blow out the one-way valve. This worked best for me and made the repair quick. The unit has been working like brand new since this repair.

I too used the paper clip, had better luck with pipe cleaners. I noticed that often times the some coffee would fly up when the lid was closed so I figured that the problem with the out spout becoming clogged was not a brewer problem, but a K-cup problem.

I emailed Keurig with this solution but they weren't receptive. The clogging problem is solved by USING A PUSH PIN OR WHATEVER TO PUNCTURE THE K-CUP (this releases the pressure in the cup, hence no coffee evacuating into the brewer outlet hole) THEN PUT THE K-CUP in the brewer and proceed.

I believe that if I'd punctured the K-Cup from day one that 90% of the problems would have not occurred. Good Brewing to all.

I had not used my brewer in about 3 months. I turned it on and the water heated up and I pressed Brew , Nothing. then the water started coming out of the over flow hose back into the water reservoir. My son took a can of compressed air that he uses to clean the computer. Put the hose of the compressed air into the hole that didn't have water coming out of it. As he did this brown water came out of the brewer where the coffee is normally made and filled a large cup. Then we put more water in the tank and he did it again. Not as brown this time. The Brewer now works. brews the correct amount of oz for what is chosen. Thank You Son. works great now.

https://www.youtube.com/watch?v=C4i7pMWb... Just follow these instructions.. Solved all my problems.

Take all removeable parts (reservoir lid / reservoir / cup rest) . Unplug & take it to sink / tub or outside table. Take a bottle of water & flip it upside down on the water entry point & force water thru machine ... should unclog asap.

OK, this works. You will need perhaps 1.5 hours+.

I have the 1-cup version, so I pour one coffee cup of water in for each cup of coffee.

This cleaning process is very frustrating at first. If you have a short fuse or limited patience, plan to do this process once per hour over a day, or an evening.

My version -

--paperclip opened up 2 joints - 2 inches+-

--with paperclip, ream out the three valves which puncture the top of the K-cup (be careful - this tip is VERY sharp - check your aim) - if major resistance, you have probably missed the path and are hitting the gasket; the back valve is most difficult to reach accurately

--2 16-oz measuring cups - you can do this with coffee cups, but the measuring cups allow clearance for the funnel and filter; a coffee cup will not

--one funnel, large enough that it sits - mostly - outside the measuring cup mouth

--1 coffee filter, paper-clipped inside the funnel, funnel inside empty measuring cup, empty measuring cup placed to receive the hot liquid, just like a coffee cup; you will use the same single coffee filter repeatedly until cleaning is finished

--10 oz. white (distilled) vinegar; pour the vinegar into the reservoir ; you will repeatedly use this same vinegar throughout the cleaning; don't discard

--power up; open/close gate to load the vinegar

-- when the machine chokes or quits, hold down the BREW key until the machine gargles, indicating all fluid pushed thru - bottom measuring cup will now have 10 oz. vinegar

-- you should see some sediment in coffee filter.

-- move funnel/filter to empty measuring cup; place as a "new empty coffee cup"

-- ream the nozzle again

-- pour the vinegar; repeat steps starting at "power up"

--- at "repeat 10 times", suddenly flow improves; can run an entire cup without holding down the BREW key

-- keep reaming; keep repeating; and after 15-20 cycles, your machine flows like a new machine.

-- now - just as the flow starts, power the machine off and let it sit for 30 minutes; then finish the cycle; repeat

-- Ok, fresh water, several runs, until water does NOT taste like vinegar; and then run water twice more - each run with fresh clean water.

All done.

BTW - some of these observations indicate that a hose was dislodged. This probably occurred because the pressure of the system exceeded the hose clamp, and blew the line off the connection. You are out of luck here, until you actually figure out how to disassemble the machine; beyond the scope of this discussion. If you can manage to get the hose reattached, with a clamp, than follow this procedure to keep the pressure off the hose in the future.

Good luck.

For those of you like me the clog wasn't the problem. I heard remedies like turn the machine upside down and smack it. But what seems to work perfect for me is to unplug the machine after every use and it resets all the internal crap and works perfect every time. Must be something wrong with a sticky valve or solenoid or something inside that unplugging resets. Hope that works for you.PS You must unplug first time for a few hours for it to reset itself

Do the following:

Drain fill tank, Remove charcoal filter pack, back wash fine mesh screen, run vinegar through system when doing this let the brew tank fill, make one cup then let the vinegar sit a few hours..last run plenty of clear water through brewer to remove the vinegar and any scale that the vinegar loosened,, put in a new charcoal filter (you can buy these at the store where you purchased your Kr.. last get a push pin (like you use to tack notes to a bulletin board).. prior to making a cup, use the push pin to make a small hole near the center of the K cup... this will relieve the pressure in the cup...do this for all K cups prior to using your K brewer will most likely never clog again... do the cleaning process about ever 6 months, but again.. use the push pin all the time...

Thanks to all of you for such great help. Due to a move, I had my things in storage for about four months. Unpacked it and tried it tonight, it was a no-go. I researched and found this wonderful site! I tried the paper clip to no avail, then I saw both Mark and Cal's posts about the tube being dried out and a burst of air would push the water through. Well, I didn't have anything to push air hard enough to shoot water through the tube except my bike pump. It did the trick! I just positioned the end of the pump (w/o the needle) right over the water hole. Take the water tank off and you will see it. I pumped hard about three times and water came pouring out of the spot where the coffee comes out. Thanks to all of you!! Susan

After having to hit the button 6 times to get a full cup of coffee (for the last 2 weeks!), here are my two cents worth..... get a small phillips screwdriver, a small flat screwdriver, wire snips, needle nose pliers, 10 small zip ties, some type of small wire poker. THIS EFFORT MAY CAUSE DAMAGE TO YOUR PLASTIC PIECES. Unplug and drain the water. Open the hatch and remove all the screws(4, I recall) holding the lever cover. Remove the cover. Then work very carefully to pry the top back cover from the machine. I was able to get the left side loose pretty easy. The right and back side clips actually broke off of my unit but didnt damage the fit. These were intended as "one way clips" with no option of repairability. I was not too worried about this damage and would rather deal with this than drop another hundred bucks on a new maker.

Flip the unit upside down and pull out the 5 screws holding the bottom on. Make sure not damage the 3 grounding wires attached to this plate. Locate the little pump motor and pull the 2 screws holding the motor. Use your needle nose pliers to squeeze and slide off the small hose clamp holding the accordion hose to the side of the pump motor. Flip the unit back over and clip the big zip tie holding the cluster of hoses below the plastic clip. You are trying to locate the bigger tube that runs down to the pump motor. Once located, clip the zip tie on the bigger tube and clip the similar zip tie on the pump motor and remove the length of tube and check valve. Take this whole thing to the sink and flush out the muck(water and vinegar). Use you wire poker to gently push into the check valve to ensure it is cleaned out and working. Blow into either end of this hose/check valve to make sure you can blow one way but not the other. If you can blow both ways, the valve needs more cleaning and poking.

You will also find a similar check valve under the hatch lever. Cut the zip ties at either end of this unit, remove it and do the same cleaning, flushing and actuating of this valve. The crud that came out of my check valves was pretty bad and was the cause of all my problems.

Reassemble everything you took apart. Make sure to get the zip ties back in place on all the tubes and get the hose clamp back on the accordion hose on the side of the pump. It is easier to feed the bigger tube up through the top of the unit before connecting it to the pump. Zip tie the cluster of tubes back under the black plastic clip. Snap the top back of the unit back in place if the tangs didnt break off and if they did, hold it on with clear tape to cover up the booger marks. Tuck the power cord back into the little horseshoe housing and reinstall the bottom cover with 5 screws.

This is a more advanced home appliance repair but only took me a little over an hour to accomplish. My unit is no longer aesthetically perfect but it made a full cup of coffee on the first and only hit of the button.

PS. I like the "industrial-mechanical" look and may just make a clear plastic cover to reinstall on the top of my maker.

This blog was so helpful! Tried the paper clip thing and it still wasn't working. I turned it over and took out the screws on the bottom, all the hoses were connected and fine. Screwed the plate back in, thought it was a gonner, turned it upside right and voila, it works!

I had trouble with the Keurig brewing short cups. It would lose its prime. I found that the model I was using had a very tight fitting lid on the water reservoir. When the Keurig tried to pump water from the reservoir a vacuum was created. The water leaving the reservoir needs to be replaced with something ... and that would be air. The pump was just not able to overcome the vacuum. It worked perfectly with the water reservoir cover removed. I wanted to use the cover so I simply drilled a small 1/8 inch hole in the cover near the back of the reservoir. This is all it took. The air coming through the hole is enough to prevent the vacuum from forming. It's been going strong for over a year.

Do not use a paper clip. Use something like a blunted plastic toothpick, or you may rupture the fragile plastic elbow above the puncture needle and cause your coffee pot to leak internally and eventually ruin the pot.

We had the same symptoms with a one week old machine. Found this forum and the paper clip worked........for 4 or 5 cups....problem again. We had two boxes of k cups, great value donut shop and a breakfast blend. I tried the breakfast blend after cleaning the ports and it worked fine for maybe 2 weeks. Lots of coffee! Then I tried the donut shop and darned if it didn't fail on the first cup. I have tested this scenario numerous times and the problem is 100 pct repeatable. The batch of VIPs is bad or the k2 machine just dislikes donut shop coffee. It is in a regular cup, with a blue label and it is from keurig. Purchased at Costco.

Instead of paper clip, try a used guitar string. Works for me and I just did it again. Shocking you can get the guitar string about 3 inches up there because of it's flexibility and the string winding provides a bit of cleaning. Hit it to brew with no cup in and the water is a yellow tint coming out. Just made a cup,,, awesome.

I even keep the guitar string in the corner of silverware drawer. If you're unfamiliar, choose a D or 4th string from someone 's guitar.

FOR THOSE THAT USED THE PAPERCLIP WITH NO RESULTS:

Used the paper clip and it didn't work. I placed a straw over the object that punctures a hole in the coffee pod and blew air through the line- this don't work (btw, the water reservoir needs to be detached if you're going to blow water through the line). I then sucked on the straw once for about 5 seconds and extracted a large amount of water in that short time. Coffee maker works now!!! Water was not running through at all and this fixed the back up in the line. Just as a precaution, the water is extremely hot when you extract it from the machine via a straw you will get a mouthful of near boiling water.....

I had an issue with my Keurig B44 whereby the pump would turn on but it would not draw any water up into the heating reservoir. First thing I checked was the mesh filter inside the holding tank which was fine, I then checked the pump which turned out to be pumping water normally. Next I removed the top cover and found my issue to be the one way check valve was gummed up. I removed this valve and cleaned it out with some hot water and the issue was resolved. Hopefully this can help somebody else out who may have the similar issue.
