Brewing Coffee

- Add Coffee Grounds: Place a paper filter (basket-style) or the reusable filter into the removable filter basket. Add the desired amount of ground coffee. For best results, use 1 tablespoon of ground coffee per cup.
- Place Carafe: Ensure the carafe lid is securely in place and position the empty carafe on the "Keep Hot" plate.
