- Press the 'CARAFE TEMP' button to cycle through temperature settings: 185°F, 195°F, 205°F.
- The coffee maker will keep coffee warm for up to 4 hours.

5.6 Smart Anti-Drip Feature
The coffee maker features a smart anti-drip system that pauses the coffee flow when the carafe is removed from the heating plate. This allows you to pour a cup mid-brew without mess. Ensure the carafe is returned within 20 seconds to prevent overflow from the filter basket.

6. Maintenance and Cleaning
6.1 Daily Cleaning
After each use, unplug the coffee maker. Remove the reusable filter and filter basket, discard used coffee grounds, and rinse them under running water. Wash the carafe with warm, soapy water. All BPA-free plastic parts and the glass coffee pot are dishwasher safe (top rack recommended).
6.2 Reusable Filter Care
Regularly clean the reusable filter to prevent clogs and ensure optimal coffee flow. Rinse thoroughly after each use. For deeper cleaning, use a soft brush to remove any stubborn coffee residue.

6.3 Auto-Clean Function and Reminder
The coffee maker features an auto-clean technology to help maintain its performance. After approximately 60 uses, the 'CLEAN' indicator on the display will flash, reminding you to run a cleaning cycle. To initiate the auto-clean cycle:
- Fill the water reservoir to the 12-cup MAX line with a mixture of water and white vinegar (e.g., 1 part vinegar to 2 parts water).
- Place the empty reusable filter into the filter basket, and ensure the carafe is on the heating plate.
- Press and hold the 'BOLD / CLEAN' button for 3 seconds. The 'CLEAN' indicator will light up steadily, and the cycle will begin.
- Allow the cycle to complete. Discard the cleaning solution.
- Run two full cycles with fresh, cold water only to rinse the system thoroughly.
6.4 Descaling
Even with the auto-clean function, mineral deposits (limescale) can build up over time, especially in hard water areas. Regular descaling is recommended every 2-3 months, or when the 'CLEAN' indicator flashes. Follow the auto-clean procedure using a descaling solution or white vinegar.
7. Troubleshooting
If you encounter issues with your coffee maker, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Coffee maker does not turn on. | Not plugged in; power outage; faulty outlet. | Ensure the power cord is securely plugged into a working electrical outlet. Check your circuit breaker. |
| Coffee does not brew. | Water reservoir empty; carafe not properly seated; brew cycle not initiated. | Fill water reservoir. Ensure carafe is correctly placed on the heating plate. Press the 'BREW / OFF' button. |
| Coffee tastes weak. | Insufficient coffee grounds; 'BOLD' setting not selected; coffee grounds too coarse. | Add more coffee grounds. Select 'BOLD' brew strength. Use a finer grind of coffee. |
| Coffee overflows from filter basket. | Too much coffee grounds; filter clogged; carafe removed for too long. | Reduce coffee grounds. Clean the reusable filter. Return carafe quickly when using anti-drip feature. |
| Warming plate settings not retained. | This model requires manual adjustment of the auto shut-off time for each brew cycle if different from default. | Remember to set the desired auto shut-off time using the 'AUTO OFF' button before each brew. |
