7. Maintenance and Cleaning
Regular cleaning and maintenance ensure the longevity and optimal performance of your coffee maker.
- Daily Cleaning:
- Always unplug the coffee maker and allow it to cool completely before cleaning.
- Remove and discard used coffee grounds and the paper filter.
- Wash the glass carafes and filter funnel with warm, soapy water. Rinse thoroughly and dry.
- Wipe the exterior of the machine, including the LCD panel, with a damp cloth. The button-free design of the LCD panel facilitates easy cleaning.
- Clean the warming plates with a damp cloth. Do not use abrasive cleaners or scouring pads.
- Descaling:
To maintain the performance of the coffee machine, descaling is recommended regularly, approximately after 2800 uses. Mineral deposits can build up over time and affect brewing efficiency.
- Prepare a descaling solution. This can be a mixture of white vinegar and water (e.g., 1 part vinegar to 2 parts water) or a commercial descaling agent following its specific instructions.
- Pour the descaling solution into the water reservoir.
- Run a brewing cycle without coffee grounds.
- After the cycle, discard the solution from the carafe.
- Run several cycles with fresh, clean water to thoroughly rinse the machine and remove any residual descaling solution.

8. Troubleshooting
Refer to this section for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Coffee maker does not turn on. | No power supply; main switch off. | Ensure the power cord is securely plugged into a grounded outlet. Check if the main power switch on the back of the machine is in the "ON" position. |
| Coffee is not brewing. | Insufficient water; brew cycle not initiated; filter basket not correctly placed. | Check water level in the reservoir or water supply connection. Ensure a brew mode is selected on the LCD panel and the start button is pressed. Verify the filter basket is properly seated. |
| Weak or poor-tasting coffee. | Incorrect coffee-to-water ratio; stale coffee grounds; improper grind size. | Adjust the amount of coffee grounds. Use fresh, quality coffee. Ensure the grind size is appropriate for drip coffee makers. |
| Filter basket overflows. | Too many coffee grounds; filter not properly seated; fine grind. | Reduce the amount of coffee grounds. Ensure the paper filter and funnel are correctly positioned. Use a coarser grind if necessary. |
| Water leaks from the machine. | Loose water pipe connection (if plumbed); carafe not correctly positioned. | If using automatic filling, check and tighten all water pipe connections. Ensure the glass carafe is properly placed on the warming plate to receive brewed coffee. |
| LCD touchscreen unresponsive. | Temporary software glitch; power issue. | Turn off the main power switch, wait a few seconds, then turn it back on. If the issue persists, unplug the machine from the power outlet for 1 minute, then plug it back in. |
