Vortex Technology – Showerhead design evenly saturates grounds for full flavor. Use cold filtered or spring water for best taste. Avoid distilled or softened water to reduce bitterness and buildup. Smart-Clean System – The automatic cleaning cycle helps prevent scale buildup that can slow brewing, impact taste, or cause early machine failure. Run the Auto Clean cycle regularly to maintain heating performance and avoid premature issues. Keep Hot Carafe Plate – Keeps coffee warm up to 120 mins. Use KEEP WARM button to set 6–120 mins or OFF. Unit shuts off automatically after timer ends for safety and energy savings. Brew Strength Selector – Choose a stronger brew by slowing the cycle for bolder coffee. Be sure to use filtered water to avoid excess minerals that can affect flavor and internal components. Avoid overfilling the reservoir (12-cup max) to prevent leaking. Removable Filter Basket – Dishwasher-safe and fits basket-style filters. Insert properly to avoid grounds in coffee. Return carafe within 30 sec during Sneak-A-Cup use. Ensure carafe and lid are secure to prevent leaks.
