Operating Instructions
Brewing Coffee
- Fill Water Reservoir: Open the lid and fill the water reservoir with fresh, cold water up to the desired level indicated on the side. Do not exceed the 12-cup maximum fill line.
- Add Coffee Grounds: Swing out the brew basket. Insert a standard basket-style paper filter or use the permanent filter (if included). Add the desired amount of ground coffee. A general guideline is 1 tablespoon of coffee per cup, adjusting to personal preference. Close the brew basket securely.
- Place Carafe: Ensure the empty glass carafe with its lid is placed correctly on the heating plate.
- Select Brew Strength: Press the Strength button to toggle between Regular and Bold brew settings. The selected setting will be displayed.
- Small Batch Brewing: If brewing 1-4 cups, press the Small Batch button for optimized brewing.
- Start Brewing: Press the Brew button to begin the brewing cycle. The indicator light will illuminate.
- Pause and Pour: The coffee maker features a Pause and Pour function, allowing you to temporarily remove the carafe to pour a cup before the brewing cycle is complete. Replace the carafe within 20 seconds to prevent overflow.
- Keep Warm: After brewing, the heating plate will keep the coffee warm for a set period (typically 2 hours) before automatically shutting off.
Setting the Clock and Auto Brew
- Set Clock: Plug in the coffee maker. The display will flash. Press the Hour and Minute buttons to set the current time. Hold the buttons for faster adjustment.
- Set Auto Brew Time: Press the Auto Set button. The display will flash "AUTO". Use the Hour and Minute buttons to set the desired time for brewing to start.
- Activate Auto Brew: Press the Auto Set button again to confirm. The "AUTO" indicator light will illuminate, indicating the auto brew function is active. Ensure water and coffee grounds are loaded before setting.
Maintenance and Cleaning
Daily Cleaning
- Always unplug the coffee maker before cleaning.

- Wipe the exterior of the coffee maker with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
- Do not immerse the coffee maker base in water or any other liquid.
Descaling (Clean Cycle)
Mineral deposits from water can build up over time, affecting performance and coffee taste. The coffee maker features a "Clean" cycle to facilitate descaling.
- Empty the water reservoir and remove the water filter.
- Fill the water reservoir with a mixture of 1 part white vinegar and 2 parts water. For example, 4 cups of vinegar and 8 cups of water for a full reservoir.
- Place an empty paper filter in the brew basket and position the empty carafe on the heating plate.
- Press the Clean button. The indicator light will illuminate, and the cleaning cycle will begin.
- Once the cycle is complete, discard the vinegar solution.
- Run two full cycles with fresh, clean water to rinse the coffee maker thoroughly.
Water Filter Replacement
