Check and set water hardness

Share with friends

Ready to start making café-quality third wave coffee from home? Part of the setup process for your new Oracle® is determining the hardness of the water in the tank. First, dip the included test strip into the water tank. The water hardness level is indicated by the number of red squares displayed on the test strip. For example, three red squares indicate a water hardness level of 3. To program the level on your machine, rotate the 'Select' dial and press it again to set the number. If your water hardness test comes out to 4 or 5, we strongly recommend that you switch to an alternate, filtered water source. This is important because the level of water hardness can affect the taste of your coffee and the maintenance requirements of your machine. Remember to never use distilled water or water with low mineral content since it will significantly impact both the taste and functionality of your machine.
