8. DESCALING

n

Calcium build-up frequently occurs in drip coffeemakers. This build-up is normal and is caused by
minerals commonly found in drinking water. Periodically, your coffeemaker will need cleaning to remove
calcium or mineral deposits that may form. You will know when your unit will need descaling when you
notice an obvious slow down in brewing time.

n

We recommend descaling your unit with a solution of white vinegar and cold water or a suitable
descaling agent. A solution of two tablespoons of white vinegar to one carafe of cold water works best.
Pour this solution into the water tank, and follow your normal operating instructions, without a filter in
the filter basket.

n

When the brew cycle is finished, empty the carafe and rinse with water. Refill the water reservoir with
cold water only and repeat the brew cycle with water only, twice more. This will rinse out any remaining
vinegar solution. 

- We strongly recommend decalcifying your coffee maker any time the brewing time slows down or when

you begin to notice excessive steaming. The frequency of decalcifying will depend on the hardness of
your water. We suggest decalcifying approximately every 80 brew cycles if you have soft water or every
40 brew cycles if you have hard water.
