Setup
1. Unpacking and Initial Cleaning
- Remove all packaging materials and stickers from the appliance.
- Wash the glass carafe and its lid, and the removable filter holder in warm, soapy water. Rinse thoroughly and dry.
- Wipe the exterior of the coffee maker with a damp cloth.
- Before brewing coffee for the first time, operate the coffee maker with only water (without coffee grounds) for two full cycles to clean the internal components.
2. Placement
- Place the coffee maker on a flat, stable, heat-resistant surface.
- Ensure there is adequate ventilation around the appliance.
- Do not place the appliance directly under wall cabinets as steam may damage them.
Operating Instructions
1. Filling the Water Tank
- Remove the removable water tank from the coffee maker.
- Fill the water tank with fresh, cold water up to the desired level, using the markings on the tank or carafe as a guide. Do not exceed the maximum fill line.
- Place the water tank back into its position on the coffee maker.
2. Inserting the Filter and Adding Coffee
- Pivot the filter holder outwards.
- Insert a standard paper filter (size 1x4 or similar, depending on model specifics) into the filter holder.
- Add the desired amount of ground coffee into the paper filter. A general guideline is one tablespoon of coffee per cup (150ml). Adjust to your taste.
- Pivot the filter holder back into its closed position. Ensure it is securely closed.

3. Starting the Brewing Process

4. Anti-Drip Function
- The coffee maker is equipped with an anti-drip system. You can temporarily remove the carafe during the brewing cycle to pour a cup of coffee without drips.
- Ensure the carafe is returned to the heating plate within 20 seconds to prevent overflow from the filter holder.
5. Keep Warm Function and Automatic Shut-off
- After brewing is complete, the heating plate will keep the coffee warm.
- The appliance features an automatic shut-off function for safety and energy saving. It will turn off automatically after a period of inactivity (typically 30-40 minutes).
Maintenance and Cleaning
Daily Cleaning
- Always unplug the coffee maker and allow it to cool completely before cleaning.
- Discard the used paper filter and coffee grounds.
- Wash the glass carafe, its lid, and the removable filter holder in warm, soapy water. These parts may also be dishwasher safe (check product manual for specific details).
- Wipe the exterior of the coffee maker, including the heating plate, with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
- Never immerse the main unit of the coffee maker in water or any other liquid.
Descaling
- Mineral deposits from water can build up in your coffee maker over time, affecting performance and coffee taste. Descale your appliance regularly, depending on water hardness and frequency of use (e.g., every 1-3 months).
- Use a commercial descaling solution suitable for coffee makers, following the manufacturer's instructions. Alternatively, a solution of white vinegar and water (1 part vinegar to 2 parts water) can be used.
- Run the descaling solution through a full brewing cycle.
- After descaling, run at least two full cycles with fresh water only to rinse out any descaling residue.
