Water seems such a simple thing but it truly can cause a great number of issues with your machine. – Using the right water is essential to achieving the best flavor from coffee and making sure the machine operates without interruption. We do not recommend using highly filtered or demineralized water such as reverse osmosis, ultra filtered, demineralized or zero-filtered waters. The machine is not designed to operate with these kinds of filtered water as there is too little or no mineral content which is required for the sensors within the machine to operate. These types of waters can also alter the taste of the coffee from what one would normally expect.
If these types of waters must be used, we recommend adding in a small bottle (6oz) of spring or tap water when filling the water tank to provide the minimal content of minerals required for the machine to operate without hassle.
