DECALCIFICATION
Decalcification refers to the removal of calcium
deposits that form over time on the metal parts
of your coffeemaker. The mineral content of the
tap water in your area and the frequency of use
affects the rate of the calcium buildup, which can
affect the functioning of your coffeemaker and
the flavor of your coffee.
For best performance from your coffeemaker,
we recommend cleaning it whenever the CLEAN
LED indicator lights up.
NOTE: Before decalcifying your unit, remove
the charcoal water filter from the water
reservoir.
To clean:
1. Fill the water reservoir to capacity with a
mixture of 1⁄3 white vinegar and 2⁄3 water.
2. Press and hold the CLEAN button. When the
CLEAN LED indicator flashes, the coffeemaker
is in Clean mode. Release the button.
3. When the cycle is completed, 5 beeps will
sound and the coffeemaker will shut off.
4. If the CLEAN indicator illuminates once
more, repeat the cleaning procedure with
a fresh solution of vinegar and water.
NOTE: One cleaning cycle is usually sufficient.
5. When the CLEAN indicator remains off, run
one cycle with a full reservoir of fresh, cold
water to rinse the unit.
6. Return the charcoal water filter to the holder
inside the water reservoir and your
coffeemaker is ready to brew!
