Understanding the Error Lights

Before diving into the specific error lights, it’s essential to understand their meanings. The Delonghi Magnifica S Smart typically has three error light indicators:

  1. Power Light: This light indicates the power status of the machine. A solid green light means the machine is properly powered on, while a red light could indicate a power issue.
  2. Coffee Grounds Bin Light: When this light is on, it suggests a problem with the coffee grounds bin. It may be incorrectly placed or full, requiring attention.
  3. Descaling Light: The descaling light signals when it is time to descale the machine. Descaling helps remove mineral deposits that can affect performance.
