Sage coffee machines are designed for precision and performance, but like any coffee machine, they can develop issues over time, particularly if maintenance is overlooked. Common problems include machines not heating properly, low or no water flow, grinder issues, or inconsistent milk frothing. Many of these faults are linked to limescale build-up, blockages, or incorrect settings rather than major component failure. Sage machines often provide warning lights or alerts to indicate when something is wrong, making it easier to identify the issue early. Regular cleaning, descaling, and correct setup are essential to keeping the machine operating correctly. In many cases, simple checks and maintenance can resolve the problem, but persistent issues may require more detailed troubleshooting or professional support.
