If you search the internet you will find a number of posts complaining that their Keurig single serve coffee maker quit working, or problems with water flow, a plastic taste to the coffee or confusion on how to properly descale the brewer.
For example, I looked at the reviews for the Keruig B60 Special Edition Gourmet Single-Cup Home-Brewing System on Amazon.com, and noted that approximately 10% of the 945 reviews had some complaint about this unit. The response of Keurig’s Customer Service Department seems to be inconsistent, but it appears quality control and better education of customers is helping with the problems.
The following video is how one customer solved the problem of his Keurig from not working:
In addition to the solution on this video it appears that because the water lines from the reservoir to the brewer are quite small they can easily become clogged with debris. The best solution for this problem is to run some distilled water through the unit without a k cup installed which should clear out any debris in those lines.
Another issue that can cause the brewer to quit working is the buildup of calcium or other mineral deposits, and the manufacturer recommends running a large cup of vinegar through the machine to clean it out. The following video shows how the manufacturer recommends you descale the brewer:
Here are some items you will need for descaling your Keurig coffee maker:
- You will need some white vinegar;
- You will need 8 ounces for the Keurig Mini Brewer, 48 ounces for the Keurig Mini Plus, Platinum and Special Edition home brewers and 64 ounces for the Keurig B100 home brewer.
- You will also need some distilled water.
Follow these steps:
- Pour undiluted white vinegar into the brewer’s reservoir to the fill level mark;
- Place a coffee cup on the drip tray;
- Make sure the lid is closed and then run a brew cycle;
- Pour the contents of the coffee cup back into the water reservoir, run a second brew cycle – HOWEVER, this time turn the machine off as soon as it begins dispensing the liquid into the coffee cup!
- Let the brewer stand for 30 minutes after disposing of the contents of the coffee cup before continuing;
- Fill the water reservoir with distilled water and then run another brew cycle into a coffee cup throwing the contents of the coffee cup away;
- Repeat the previous step until the reservoir is empty.
But sometimes running vinegar through your Keurig single cup coffee brewer could leave your coffee with a nasty aftertaste. To solve this problem Keurig recommends you cycle multiple brew cycles with just distilled water before resuming use of the coffee maker.
Sometimes, in particular when you first get your single serve coffee maker the coffee can have a plastic taste to it. The solution is to clean out any obstructions which are in the filter, then fill the water tank 1/2 way full with vinegar and, after letting the vinegar sit for 10 minutes, run the solution through your coffee maker. Once you complete this clean out the water reservoir, fill with distilled water, and run several brewing cycles without any k cup being installed.
