Decalcification
Decalcification refers to the removal of calcium deposits that form over time on the metal parts of the coffeemaker.
For best performance from your PerfecTemp™ Coffeemaker, decalcify the base unit from time to time. The frequency depends upon the hardness of your tap water and how often you use the coffeemaker. The flashing Clean light will indicate when you should clean your coffeemaker.
NOTE: Before decalcifying your coffeemaker, remember to remove the charcoal water filter from the water filter holder located in the water reservoir.
If the Clean sign in the digital display and the Clean LED indicator light begins to flash when the coffeemaker is turned on, it is telling you that the calcium buildup is interfering with the functioning of your coffeemaker and the flavor of your coffee. To clean, fill the water reservoir to capacity with a mixture of ¹⁄³ white vinegar and ²⁄³ water. Press the Clean button. When the Clean LED indicator glows, turn the coffeemaker on by pressing the Brew/Off button. The Clean LED will shine steadily. The coffeemaker is now in Clean mode. One cycle should be sufficient to adequately clean the coffeemaker. When the cycle is completed and the five beeps sound, the coffeemaker will shut off. Turn the coffeemaker on to see if the Clean sign and Clean LED continue to flash. If they do, turn coffeemaker off and then repeat the cleaning procedure with a fresh solution of vinegar and water.
If the Clean sign and Clean LED no longer flash, turn the coffeemaker off and then run one cycle of fresh, cold water through the unit before using the unit again to brew coffee.
Notes on the Clean Function
Pressing the Clean button cancels all other settings. If it is pressed accidentally, press it again to return the coffeemaker to all its previous settings. Pressing Brew/Off will also exit the Clean mode and turn the coffeemaker off.
