We have owned this Mr. Coffee coffee maker for only a few months.in that time we have had nothing but problems! First and foremost the coffee has always been weak requiring large amounts of coffee to make the coffee strong enough. Many times all the grounds don't even get wet from the water going through. Also, every other week the clean light comes on and I have to run 2 cups of vinegar through it followed by two full pots of water. This works for a few pots of coffee and then it becomes weak again. We even use the round disk water filter which we replace every month. Luckily, I purchased mine from Costco and it is going back for a refund!
