I’ve never used distilled water in my Keurig. When I took it up to Wisconsin, I used jugs of regular water from the grocery store because you could practically see the calcium in the tap water up there, but since I came back to Missouri, it’s always been tap water. Every few months I run a cup of vinegar through it in case of a buildup. The only issue I’ve had actually has to do with wet grounds from the k-cup backing up into the needle. This can be solved by twiddling a paper clip through the hole in the needle and maybe running the machine once without a k-cup to clear it out. That’s only happened once or twice in the several years I’ve had it.Any coffee maker can last for many years. The key is to only use DISTILLED water in it. All other kinds of water have minerals that build up over time and foul up the machine. Tap water is especially damaging.
We went through several coffee makers, using filtered bottled water, before learning our mistake. We even went through two Keurig machines. Once we switched to distilled water, we never had a single problem again. In fact, our current machine (Keurig) was starting to have problems just before we switched to distilled. After a couple of weeks of using distilled water, the mineral buildup seemed to have cleared out on it’s own, because it began working good as new, and has ever since.
