I was in Goodwill earlier today and spotted a fancy looking Keurig B70 coffeemaker on a shelf away from the others. It was a little dusty and looked to have a bit of hard water residue in the bottom of the water reservoir but it powered on when I plugged it in so for $12, I decided to take a chance on it. Worst case scenario, I could bring it back within 10 days for a store credit.
Wben I got it home, filled up the water reservoir, and ran out a cup of hot, albeit decidedly cloudy looking water. Running through all the menu functions, I determined that except for one LED on a selector button, the machine was completely functional and whisper quiet. This was further reassuring as some Keurigs tend to get noisy as they age. So having passed the functionality test, I filled the reservoir with a 50/50 white vinegar and water solution and flushed it out with repeated brew cycles until the reservoir was empty, then repeated the process with clear water. By the time I'd done this, the water was coming out much clearer so I and gave the whole machine a thorough cleaning, which it badly needed. As a final test, I made a cup of Twinings Chai Latte but it came out tasting sour. It didn't take long to figure out despite running clear water through it, there must have still been some vinegar left in the system and it didn't take much to curdle the milk in the chai so I ran more water through, tasting it each cup that came out, until I was satisfied the vinegar was gone. Then I made another cup of chai latte and it tasted fine. Goodwill's pricing is so bizarrely random that the other two machines they had in stock, both base model K60 machines missing their drip trays, were priced at $25 each. The B70 was their top-of-the-line prior to the introduction of the Keurig 2.0 line and thus does not have the obnoxious built-in digital rights management to tell me which K-cups I can and cannot use with it. It was also complete except for the optional charcoal filter, which I always use in my Keurigs, even though my water isn't terribly hard. So for now, it has the one out of my K60 and I've ordered another to replace it. I guess I'll now have to decide whether to take the one I've been using in my kitchen to my office whenever we return to teaching face-to-face. |

Access to the guts of the Keurig is through the bottom. You're probably right that I ought to take the bottom plate off and at least give it a visual inspection but that said, I'm not totally convinced what I saw in the bottom of the water reservoir was calcium/lime deposits. There was any real evidence of obstruction. Water was flowing freely through it, even before I cleaned it. The more I think about it, I believe the unit may have sat idle for an extended period before it was donated, with dust collecting the damp plastic and adhering as it dried, initially giving the appearance of hard water deposits but those would have been much more difficult to remove. It washed out too easily with a soapy sponge.

You might give this cleaner a try, it's made from citric acid, it should clean better than vinegar and also will not have the vinegar smell. Mike CLICK HERE TO GO TO n0oxy's LINK |

I've had a Keurig in for repair from a friend of mine for a while now. I was using it for a while and it worked fine, but it stopped heating up and got stuck in preheat mode. I opened it up... and man it was a bear to take apart. And this is coming from a guy who's accustomed to working on German cars. It's a stupidly complex chunk of plastic. Really, it's only a motherboard, pump, and heater. Yet it's got way too many parts, hoses, and wires.
They make a lot of different models, of course, some may be simpler. But my point is that disassembly for descaling may be more trouble than it's worth if you can just run some vinegar through it and achieve the same result. Just sayin. Anyway I think I got mine working again. I say 'mine' because I think I'm keeping it lol. I youtube'd the problem and only one video fit the bill, and it was some guy who noticed one broken wire to the microswitch that tells the machine that the cover thing is closed. Well mine had no broken wires, but I do know that microswitches wear out. Replaced it and so far, so good. |

If it's sat for a while it could have grown severe mold. CLICK HERE TO GO TO gregvacs28's LINK

Yeah, it's somewhat of an anomaly that I even like Keurig brewers with their proliferation of circuit boards and inherent inaccessibility for repair. While it runs completely counter to the philosophy behind my appliance purchases, I do enjoy the convenience. That said, I've never encountered a Keurig with 'security screws' but I have only had the earlier first-generation units. I guess those screws could have been added as a 'feature' to the Keurig 2.0 machines, which I have studiously avoided for other reasons. The whole idea that a manufacturer thinks they should be able to exert digital rights management over my coffee is both intrusive and abhorrent to me.
After using this new (to me) Keurig for a few days, I have no real complaint about it from an operational standpoint. Everything seems to be fully functional and it makes great tasting coffee. Nonetheless, I plan to take the bottom plate off at some point soon to examine it for signs of scale or mold. I have only ever run a vinegar solution through coffemakers to clean them. Vinegar is an effective cleaning agent and totally safe, should I accidentally ingest some. Since the water initially came out cloudy on this machine, I kept running clear water through it after the vinegar solution until it came out clear with no 'floaters' so I'm reasonably comfortable that the machine is sanitary and safe to use. |

Have you tried allen wrenches. Maybe the ones with ball ends. |
