For those who have encountered the "Add Water" message from there Ninja brewer, I did some digging to find out what causes it and how to fix it. There are four main issue that can result in the "Add Water" message and only one of them is the situation with low water in the machine. The first issue is with the water tank being low which all users will soon encounter. The second issue is that the reservoir isnt properly seat into the machine which will eventually trip most users up as the tank will appear to be properly seated yet the brewer will not recognize it as such. Third is the presence of air within the system which you can fix by simply hitting the Start button a few times to get the machine to prime properly. The fourth and final issue is the result of a faulty pump or a blockage within the line which leads to the brewer being unable to properly dispense the brewed coffee. Usually the solution is to run a descaling cycle before assuming that the brewer’s pump has failed. Ninja brewers tend to accumulate alot of water scale if users are on hard water and do not perform a descaling cycle every few month. Thus, my question to those who have encountered this issue is whether or not the descaling cycle has ever brought a Ninja brewer back from the brink of "Add Water" errors or if at that point the pump is usually considered a lost cause.
