Ninja Coffee Bar

These are refurbished(used) so I was not surprised by the used shown on the item. The pot was perfect and the reservoir looked brand new, even if the lid was soiled and scratched. There was a set of comprehensive instructions attached to the maker describing how to clean it properly prior to use. I missed the "flush" cycle the first two times I cleaned it, so it got three cleanings before I could get the "clean" light to extinguish. I set the timer to brew the next morning and woke to a disappointing half pot of coffee. My first thought was the carafe setting dial was on the wrong setting, it wasn't. Later that day I ran the clean cycle again. I ensured I followed the directions to the T; correct vinegar to water, filled to the clean max line, set a reminder to complete the rinse cycle, and voila, clean light is out again. To be safe, I ran a cycle to brew coffee, just to make sure the brew would work. It did, but the light came on midway through the brew; it did brew a full pot though, almost to the top of the carafe. I cleaned it again, followed by the flush cycle, light goes out. I set it again to brew for the morning. Low and behold, another half pot of coffee. I resolved to do the four hour "enhanced clean" cycle. I set reminders to follow up with a flush so I was sure it was done correctly. Halfway through the cleaning, I pull out the carafe and pour the contents into a clear beaker for inspection. it was clear with no debris what so ever. The cycle completes and I dump the contents to start the flush cycle. Quarter way or so through the flush cycle, I pull the carafe and again inspect the liquid. Again, clear as glass. I put the carafe back under the flow to let the flush complete. Light goes out, I set it up for a morning brew. To my horror, I awake to find I had forgotten to dump the rest of the flush cycle out of the carafe the night before. I was pretty happy it only brewed half a pot this time, even though it was enough to get all over the counter. The clean light was back on. I opened the instructions in the book and see that the machine has to be cleaned/flushed at least once weekly more if you have hard water. If the clean light is on, you only get a half pot I guess. It must be a very sensitive sensor in this thing. The standard clean cycle is not automatic and it cost nearly two hours of dedicated time to complete. I don't give my cars that much attention. I gave up and returned this coffee maker/ life spoiler back to the refurbishment company, the return went much better then the rest of this experince...
