Water Comes Back Into Reservoir and Short-Cups Me I have two Keurig B70s with the same problem: they worked great for a few months. Then I started getting short cups and had to press the brew button twice for one cup of coffee.
I noticed during these times that water was going BACK into the reservoir from that plastic piece at the top left. That can't be right!
Anyone have a solution to this problem? I have so many K-cups, I'd hate to just get rid of the machine.
I found a solution! Take a can of compressed air, the kind you use to clean your keyboard, and shoot a few short bursts into the water drain after removing the water reservoir. Do this when the machine is off and the water has cooler. OR, use a small needle to poke around in the top piercing needle for a few seconds then run a cycle without a k-cup. You should get a full cup of hot water with lots of coffee grounds floating around. It's a quirk but this resolution really works!
Thanks, the paperclip method does work. Our B-70 started to brew "shortened" cups and water was back filling into the reservoir. I carefully inserted one end of a paperclip into the upper and lower needles and then cycled a couple of hot water only cups. While I did notice some coffee grounds, it certainly didn't look as though it were enough to be the cause of the problem. But... it did work.
I have to say though, because this is the second machine we've had in two (2) years, the novelty of individual, one cup brewing is starting to wear off. Having to scour the internet to solve stupid coffee maker problems is for the most part unnecessary and a waste of time. If this kind of stuff keeps happening, I'll be more than happy to go back to conventional coffee brewing.
I am so sorry to "see" some of the anger and hostility from Keurig users on this site. I have been a Keurig user for well over 2 years now at both my office and at home. There was a moment when I became angry as well with the short cup and no cup issue. I too spoke with Keurig customer service who was very nice and helpful, but only solved the problem for a short while. Yes, I use bottled water too, but NO water is 100% pure. Even restaurants have to descale their equipment so why would Keurig be any different? What I have learned: 1) there is not just one place to plunge the paper clip into for cleaning - there are 2 and another that needs attention: The obvious spouts at the bottom under the k cup, the top above it (the one I used to miss) and the one at the bottom of the resorvior. But more important: Vinegar may work sometimes as a descaler, but is certainly not the best and may stop working for you completely as it did me. Most of us did not use it as directed in our manual anyway. I was one who thought it was magic - a good run through and everything would be perfect. Not so. I have been happy again for 10 months now having found a commercial descaler: Dezcal (here on Amazon). Use it as directed - overnight. And if your scale-buildup problem has been around for awhile, you may have to do it twice. It keeps both my machines clean and sparkling. And if they act up just a little, one overnigh treatment now does the trick.
By the way - I have both a B77 and a B70 and if you do not think my suggestions are helpful to the masses, then just ignore them. Meanwhile, I will sit back and enjoy my Timothy's French Roast.
ours does the same thing. we too, purchased from Costco, but according to other reviews the same thing will happen in another few months, even if we exchange it. we're getting a different system entirely.
The problem the B70's series is a pump failure. Pump failure or loss of pump power on B70-77 is a know issue. Descaling has nothing to do with some of these failures on the discussion boards. Classic signs: a spurt of water in your cup, water trickling back into the reservoir and then complete silence...or complete silence after you select brew. The lcd panel will read "brewing" and then return to ready after a minute. If you take apart your B70 - 77, you will see a series of tubes, wires and small cannisters that work to push the water through the tubes. These small cannisters are pumps. Keurig will replace models from these "batches" (2009-2010), although it will probably be a refurbished model. My "new" brewer is arriving in 3-7 days...
Hi Miz. I have gone through 4 replacement brewers now. There is something seriously wrong with the B70 and B77. They have had many returns on these units. I know of several folks that are currently on their 3rd or 4th brewer. About 7 or 8 months ago they stopped production of the B70 and it was not even available for purchase for about a month so they know something is wrong. I just feel bad for all the people that will buy these bad units used from the other sellers thinking they are getting a deal.
In my opinion I would get the Mini. I have friends that got this unit the same time I got my B70 and they have not had any problems yet. We originally got the B70 because we thought we were going to use all the different cup sizes but we didn't. The Mini is a bit more of a hassle but at least it's not 170 bucks!
I had the same problem. I was told that I needed to descale the keurig which I did. It did improve it slightly but i happened to have purchased my keurig from Costco and they just exchanged it for a new one no questions asked.
we had the same problem, and actually found it was an issue with the cups we were using. we took apart one cup where the brewer didn't give us a full cup of coffee, and compared it to one that did. the short-cupped one was missing a filter paper thingy in it, so we don't buy those cups anymore. the only other thing we do that others might not is run it without a cup at 4-5 times a week - my 11yo son uses it to get hot water for oatmeal in the morning :)
I have that same problem!!! I had descaled it, and 'cleaned' the machine parts with a paperclip (per instructions by rep on phone) and I still got short-cupped. I talked to the company a few days ago and complained, so they thought it could be a 'faulty k-cup holder' and they sent me a replacement. Well I put it in, and now my machine does NOT work at all! I called the company and they think the machine could be defective and are sending me out a new one. I hope THIS new one works!!!!
Person....Clint, Do you own a B70 or B77? Probably not. Do you actually believe that all of us have not tried that already? That we haven't spent hours on phone support? This is a specific issue with specific models. The B70 and B77.
I use only bottle water with all of my brewers. The 1st one stopped pumping after 2 weeks. Identified by support as a problem with the reservoir. They sent me a new brewer. 2nd one, same problem, 3rd one bad pump, 4th one same problem. I have yet to make it a full 6 months with any brewer. regardless, Kerurig support suggests descaling every month. I descale monthly and still have problems. Not to mention they now have a new product out specifically as a descaling solution that they had to recall because it's contaminated with mold.
