Important Safeguards
When using electrical appliances, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and/or injury to persons, including the following:
- Read all instructions before using the coffee maker.
- Do not touch hot surfaces. Use handles or knobs.
- To protect against fire, electric shock, and injury to persons, do not immerse cord, plugs, or coffee maker in water or other liquid.
- Close supervision is necessary when any appliance is used by or near children.
- Unplug from outlet when not in use and before cleaning. Allow to cool before putting on or taking off parts, and before cleaning the appliance.
- Do not operate any appliance with a damaged cord or plug or after the appliance malfunctions, or has been damaged in any manner. Return appliance to the nearest authorized service facility for examination, repair, or adjustment.
- The use of accessory attachments not recommended by the appliance manufacturer may result in fire, electric shock, or injury to persons.
- Do not use outdoors.
- Do not let cord hang over edge of table or counter, or touch hot surfaces.
- Do not place on or near a hot gas or electric burner, or in a heated oven.
- Always attach plug to appliance first, then plug cord into the wall outlet. To disconnect, turn any control to "off", then remove plug from wall outlet.
- Do not use appliance for other than intended use.
- The carafe is designed for use with this appliance. It must never be used on a range top.
- Do not place a hot carafe on a wet or cold surface.
- Do not use a cracked carafe or a carafe having a loose or weakened handle.

- Place the carafe on the warming plate.
- Plug the coffee maker into a standard electrical outlet.

Operating Instructions: Brewing Coffee
- Fill Water Reservoir: Open the lid and fill the water reservoir with cold, fresh water to the desired level, using the water window for guidance. Do not exceed the 12-cup MAX line.
- Add Coffee Grounds: Place a standard basket-style paper filter (or the reusable filter, if included) into the removable filter basket. Add the desired amount of ground coffee. A general guideline is one level tablespoon of coffee per cup, but adjust to your taste.
- Position Filter Basket: Close the lid, ensuring the filter basket is properly seated.
- Place Carafe: Place the empty carafe with its lid securely on the warming plate. Ensure it is centered to activate the drip-stop mechanism.
- Start Brewing: Plug the power cord into a standard electrical outlet. Press the power switch to the "ON" position. The indicator light will illuminate, and brewing will begin.
- Pause and Serve: The coffee maker features a pause-and-serve function. You can temporarily remove the carafe during the brewing cycle to pour a cup. The flow of coffee will automatically stop. Replace the carafe within 30 seconds to prevent overflow.
- Keep Warm: Once brewing is complete, the warming plate will keep the coffee hot. The power indicator light will remain on until the unit is manually turned off.
- Turn Off: After serving, press the power switch to the "OFF" position and unplug the coffee maker from the outlet.
Maintenance and Cleaning
Daily Cleaning
- Always unplug the coffee maker and allow it to cool completely before cleaning.
- Remove the filter basket and discard the used coffee grounds and paper filter.
- Wash the carafe, lid, and filter basket in warm, soapy water. These parts are also dishwasher-safe (top rack recommended).
- Wipe the exterior of the coffee maker, warming plate, and water reservoir area with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
- Never immerse the main unit, cord, or plug in water or any other liquid.
Decalcifying (Mineral Deposit Removal)
Mineral deposits (calcium) can build up in your coffee maker over time, affecting its performance. Decalcify your coffee maker every 2-3 months, or more frequently if you have hard water.
- Prepare Solution: Fill the water reservoir with white vinegar up to the 4-cup mark, then fill the rest with cold water up to the 12-cup mark.
- Run Half Cycle: Place an empty paper filter in the filter basket. Place the carafe on the warming plate. Turn the coffee maker on and let half of the solution brew through.
- Soak: Turn the coffee maker off and let it stand for at least 15 minutes to allow the solution to clean the internal components.
- Complete Cycle: Turn the coffee maker back on and allow the remaining solution to brew through.
- Rinse Cycles: Discard the vinegar solution. Fill the water reservoir with fresh, cold water and run two full brewing cycles with only water to rinse out any remaining vinegar taste.
Troubleshooting Guide
