Check and set water hardness
Checking for water hardness is an essential part of the machine setup for your Oracle® Touch as the hardness of your water can impact the flavor of your coffee. Hard water, or water with a higher mineral content, can also cause scale to build up faster in your machine. To check your water's hardness, dip the included test strip into the water tank before placing it into the machine. If your water hardness is either 4 or 5 when tested, we strongly recommend switching to an alternate, filtered water source. It's also important not to use distilled water or water with low mineral content. The reason for this is because this type of water will adversely affect both the taste and functionality of your machine.
