6. Operating Instructions
6.1 Brewing Coffee
- Fill Water Tank: Open the lid of the water tank and fill it with fresh, cold water using the glass carafe. Refer to the water level indicator on the side of the machine. Do not exceed the "MAX" line.
- Add Coffee Grounds: Place the permanent filter into the filter basket. Add your desired amount of ground coffee into the filter. A general guideline is one level magnetic spoon (approx. 7g) of coffee grounds per cup (150ml) of water, but adjust to your taste.
- Position Carafe: Ensure the glass carafe is correctly placed on the warming plate.

The programmable timer allows you to set the coffee maker to start brewing at a specific time within a 24-hour period.
- Set Current Time: When the coffee maker is plugged in and in standby mode, press the "PROG" button. Use the "+" and "-" buttons to set the current hour, then press "PROG" again to set the minutes. Press "PROG" once more to confirm.
- Set Auto-Brew Time: After setting the current time, press the "TIMER" button. The display will show "00:00". Use the "+" and "-" buttons to set your desired brew time (e.g., 7:00 AM). Press "TIMER" again to confirm.
- Prepare for Brewing: Follow steps 1 and 2 from "6.1 Brewing Coffee" (fill water, add coffee grounds).
- Activate Timer: Press the "TIMER" button once more. A small clock icon will appear on the LCD screen, indicating that the timer is activated.
- The coffee maker will automatically start brewing at the set time.
6.3 Adjusting Coffee Strength
Some models may offer a strength selection. If available, use the dedicated button (often labeled "Strength" or with coffee bean icons) to choose between regular and strong brew settings before starting the brewing cycle.
7. Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the lifespan of your coffee maker.
7.1 Daily Cleaning
- Always unplug the coffee maker before cleaning and allow it to cool completely.
- Remove the permanent filter and filter basket. Discard used coffee grounds.
- Wash the permanent filter, filter basket, and glass carafe in warm, soapy water. These parts are also top-rack dishwasher safe.
- Wipe the exterior of the coffee maker, warming plate, and water tank lid with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
- Dry all parts thoroughly before reassembling.
7.2 Descaling (Every 2-4 Months or as Needed)
Mineral deposits from water can build up in your coffee maker over time, affecting performance and taste. Descaling is recommended every 2-4 months, or more frequently if you have hard water.
- Prepare a descaling solution: Mix 1 part white vinegar with 2 parts water. For example, 1 cup of vinegar with 2 cups of water.
- Pour the solution into the water tank.
- Place the empty glass carafe on the warming plate.
- Start a brewing cycle without coffee grounds.
- After about half of the solution has brewed through, 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 to complete the brewing cycle.
- Discard the descaling solution from the carafe.
- Run 2-3 full cycles with fresh, clean water to rinse out any remaining vinegar taste or odor.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Coffee maker does not turn on. | Not plugged in; power outage; faulty outlet. | Ensure plug is securely in outlet; check circuit breaker; try a different outlet. |
| Coffee does not brew. | Water tank empty; carafe not properly placed; timer set. | Fill water tank; ensure carafe is centered on warming plate and activates the drip-stop mechanism; check if timer is active and wait for programmed time or deactivate. |
