I purchased my Ninja Coffee Bar CF091 in December 2017 as a Christmas gift to myself. From the start, the clean light would not go out. I called about this and was told that this is a common defect. Rep said hers does the same thing and her daughter just puts a sticky over it. It started not brewing a full cup or carafe so I called again and we walked thru the cleaning process, including pressing the button below the water tank and the button on the bottom of the water tank to ensure flow.
I had no problems for a bit and did not expect any since I am the only coffee drinker in the house. Sometimes, one cup a day - sometimes two, sometimes none. However, it is always cleaned and descaled. Now I am having major problems no matter how much I clean it. It only works for a few seconds then gives me 5 beeps. I cannot get a full cup of coffee at all.
Customer service says that the machine is definitely defective (which is what I was saying all along), but now since it is one month over the warranty, they would "sell" me a new machine for $149 which is $50 less than the full price. I explained that I purchased this thing from Sam's Club for $99.99 ($30 off special) and got the "there is nothing they can do" speech. I explained that there is no way I could even afford a new one from Sam's since I am now unemployed.
I tried cleaning this thing again and guess what, the clean light finally went out but still only gives coffee for 3 seconds before beeping 5 times. I also told the rep that I have many Shark/Ninja products but this is the first horrible one. I have the Rolater vacuum cleaner, EuroPro sewing machine, Ninja Blender, Ninja Mini Chopper and the piece of crap coffee bar. I will never, ever purchase another product from them.
Bottom Line: No, I would not recommend this to a friend
