    Auto-Clean System

    De-scaling With Auto Clean

    Over time, calcium deposits or “scale” may build up in your brewer. Scale is non-toxic, but if left unattended will hinder brewer performance. Regularly descaling your brewer helps to maintain quality coffee as well as the lifespan of the heating element and other internal parts that come in contact with water throughout the brew process. To make the de-scaling process as effortless as possible, an Auto Clean™ system has been programmed into your coffeemaker.

    When should I use Auto Clean?

    You should clean your black Decker CM1231SC coffeemaker after every 60 brews (approximately 2 months). If you would like to clean your coffeemaker prior to 60 brew cycles because of hard water, you may do so.

    How do I use Auto Clean?

    1. Combine 6 cups of white vinegar and 4 cups of cold water in a carafe.
    2. Pour into the water reservoir.
    3. Press and hold the On/Off button for 3 seconds
    4. On/Off Button LED illuminates (no blinking)
    5. “CL” appears in the display, blinking once per second, and the AutoClean cycle begins.

    During the Auto-Clean Cycle Function.

    1. The machine will brew approximately 5 cups of cleaning solution
    2. Part of the mixture will brew through.
    3. When the coffeemaker completes the AUTO CLEAN cycle, it shuts off automatically.

    FAQs

    Q: What is the Black & Decker CM1231SC 12-Cup Coffee Maker?

    It has a sneak-a-cupTM feature, a programmable timer, and QuickTouchTM digital controls that are all intended to provide hot, fresh coffee precisely and conveniently.

    Q: Can I make less than 12 cups of coffee?

    Indeed! To measure the precise amount you wish to brew, use the water marks on the carafe.

    Q: What is the Sneak-A-Cup™ feature?

    Just take out the carafe, and the drip will cease on its own. To prevent overflow, swap out the carafe within 30 seconds.

    Q: How long does it take to brew a full pot?

    Depending on the size of the coffee grinds and the water temperature, a 12-cup cycle usually takes 10 to 12 minutes.

    Q: What type of coffee should I use?

    For optimal effects, use drip coffee with a medium grind. Steer clear of coarse or finely ground espresso coffee, as they could interfere with the brewing process or result in overflow.

    Q: Does the CM1231SC have an automatic shut-off feature?

    Indeed. After two hours, the warming plate automatically turns off for energy conservation and safety.

    Q: How do I keep the coffee hot after brewing?

    Coffee may stay warm on the nonstick warming plate for up to two hours. For safety, the machine will thereafter turn off on its own.
