4. Operating Instructions
Brewing Coffee:
- Ensure the coffee maker is unplugged and cool.
- Fill the thermal jug with the desired amount of fresh, cold water (up to 1.25 L or 10 cups). Pour this water into the coffee maker's water tank. The external water level indicator will show the current fill level.
- Open the swing filter holder. Insert a size 1x4 paper coffee filter into the removable filter insert.
- Add the desired amount of ground coffee into the paper filter. A general guideline is one tablespoon of ground coffee per cup (150ml), but adjust to your taste.
- Close the swing filter holder securely.
- Place the thermal jug with its lid firmly on the warming plate. Ensure the lid is correctly positioned to allow coffee to flow into the jug.
- Plug the power cord into a suitable 220V electrical outlet.
- Press the On/Off button. The control lamp will illuminate, indicating that the brewing process has started.
- Once the brewing cycle is complete, the coffee maker will automatically turn off, and the control lamp will extinguish. The drip stop feature prevents dripping when the jug is removed.
- Carefully remove the thermal jug and serve your freshly brewed coffee. The thermal jug will keep the coffee warm for an extended period.
Note: For optimal temperature retention, pre-warm the thermal jug with hot water before brewing.
5. Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the lifespan of your WMF Bueno Pro Coffee Maker Thermo. Always unplug the appliance and allow it to cool completely before cleaning.
Daily Cleaning:
- Thermal Jug and Lid: Wash the thermal jug and its lid with warm, soapy water after each use. Use a soft brush for the interior if needed. Rinse thoroughly and dry.
- Filter Insert: Remove the used paper filter and coffee grounds. Wash the removable filter insert with warm, soapy water. Rinse and dry.
- Exterior: Wipe the exterior surfaces of the coffee maker with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
Descaling (Periodic Cleaning):
Mineral deposits from water can build up over time, affecting performance and taste. Descale your coffee maker regularly, depending on water hardness and frequency of use (e.g., every 2-4 months).
- Prepare a descaling solution according to the descaler manufacturer's instructions (e.g., white vinegar diluted with water, or a commercial descaling agent).
- Pour the descaling solution into the water tank.
- Place the empty thermal jug with its lid on the warming plate.
- Start a brewing cycle without coffee grounds. Allow about half of the solution to brew through, then turn off the coffee maker and let it sit for 15-20 minutes to allow the solution to work.
- Turn the coffee maker back on and allow the remaining solution to brew through.
- Discard the descaling solution from the jug.
- Rinse the coffee maker by running two full cycles with fresh, clean water only to remove any residual descaler.
Caution: Never immerse the main unit of the coffee maker in water or any other liquid.
