Coffee tastes bitter or burnt.

Safety first: Avoid leaving the coffee maker on for extended periods unattended.

• 1. Turn off warming plate sooner: Use the auto-off feature or manually turn off the unit after brewing to prevent overcooking the coffee.
• 2. Adjust coffee grind and amount: Use a medium grind and avoid overfilling the filter with coffee.
• 3. Descale: Scale can affect temperature control. Run a descaling cycle.
• 4. Check thermostat (advanced): If the warming plate runs excessively hot, the thermostat or control board may be faulty and require replacement.
