A decalcification indicator is also equipped that will notify the user when beverage quality is being affected by excess calcium build-up, at which point the unit can be quickly disassembled and thoroughly cleaned. Before heated water is mixed in with dry grounds, it goes through an advanced water filtration system that reduces levels of chlorine and other unwanted particles, providing a clean and purified taste. In addition to the on-board 24-hour clock, the DC514T can be set up for delayed brewing that will begin at a time pre-arranged by the user. This allows users to wake up to a fresh pot, acting as a major convenience for weekday mornings. Disposable filters are not required for this unit, as it is fitted with a "Gold-Tone" permanent filter that claims to provide maximum quality coffee for up to a year after purchase. For those consumers after the ultimate brewed coffee experience, an "Aroma Button" is included that slows down the brewing process, time-releasing small amounts of water to prevent over-saturation to provide coffee that is bold and aromatic.
