It brews hotter than traditional single-serve options for consistently hot coffee and includes programmable settings for adjustable strength, grind-off for pre-ground coffee, and an over-ice feature.

Setup
Before first use, wash all removable parts (water reservoir, hopper, filter basket, drip tray) in warm, soapy water. Rinse thoroughly and dry. It is recommended to run two or three cycles with just water to clean the internal components.
1. Insert Charcoal Water Filter
Remove the filter holder from the water reservoir. Insert the charcoal filter into the holder and snap it closed. Place the filter holder back into the water reservoir.
2. Fill Water Reservoir
Remove the water reservoir from the back of the unit. Fill it with fresh, cold water up to the MAX fill line. Place the reservoir back into the unit, ensuring it is securely seated. The 'Add Water' indicator light will illuminate if the water level is below the minimum.
3. Add Coffee Beans to Hopper
Open the hopper lid located on top of the unit. Pour whole coffee beans into the hopper. The hopper can hold up to 0.5 lb of beans. Close the lid to maintain freshness. The 'Add Bean' indicator light will illuminate if the bean level is low.

4. Insert Gold-Tone Filter
Press the filter basket door release button to open the door. Open the filter basket cover and insert the reusable gold-tone commercial-style filter. If using pre-ground coffee, you can add it directly to this filter. Close the filter basket cover and door.

Operating Instructions
The Cuisinart DGB-30 offers customizable brewing options for your perfect cup.
1. Select Coffee Strength
Press the STRENGTH button to cycle through Mild, Medium, or Bold options. The corresponding indicator light will illuminate.
2. Select Cup Size
Press the SIZE button to choose your desired cup size: 8oz, 10oz, 12oz, 16oz, 20oz, or 24oz. The corresponding indicator light will illuminate.

4. Choose Whole Bean or Pre-Ground Coffee
If using whole beans, ensure they are in the hopper. The machine will automatically grind them before brewing. If using pre-ground coffee, select the 'GROUND' option (grind-off feature) and add your grounds directly to the filter basket.
5. Place Your Mug
Place your mug or travel cup on the drip tray. The drip tray is removable to accommodate taller travel mugs (up to 7 inches).

Maintenance
Regular cleaning ensures optimal performance and taste. The 'CLEAN' indicator light will illuminate when descaling is recommended.
1. Cleaning the Burr Mill and Hopper
The burr mill and bean hopper are removable for easy cleaning. Twist the burr mill assembly to unlock and lift it out. The hopper can also be detached. Clean these components with a brush (provided) or warm, soapy water. Ensure they are completely dry before reassembling.
2. Cleaning the Filter Basket and Drip Tray
After each brew, open the filter basket door and remove the gold-tone filter. Discard used grounds and rinse the filter under running water. The drip tray can be easily removed and washed with warm, soapy water.
3. Cleaning the Water Reservoir
The 48-ounce water reservoir is removable for easy filling and cleaning. Wash it periodically with warm, soapy water and rinse thoroughly.
4. Descaling
When the 'CLEAN' light illuminates, it's time to descale the unit. Follow the descaling instructions in the full product manual to remove mineral deposits that can affect performance.

Troubleshooting
- Machine Not Brewing: Ensure the water reservoir is filled above the minimum line ('Add Water' light off) and the bean hopper has sufficient beans ('Add Bean' light off). Check that the filter basket and door are securely closed.
- Weak Coffee: If using whole beans, try selecting a 'Bold' strength setting. If using pre-ground coffee, ensure you are using the correct amount for your desired cup size.
- Grinder Not Working: Ensure whole beans are present in the hopper and the 'GROUND' (grind-off) option is not selected. Check that the burr mill is properly seated.
- Flashing Lights (other than brewing): Refer to the full instruction booklet for specific error codes or indicator light patterns. Often, this indicates a need for water, beans, or cleaning.
