Why Does Descale Light Come on Keurig K-Supreme?

The descale light is part of Keurig’s built-in system to alert you when it’s time to descale, or clean, the brewer. This light essentially indicates that mineral deposits, likely from the water used in brewing, have built up inside the machine. If left unchecked, these deposits can affect the machine’s performance and the taste of your coffee.

Even after descaling your machine, if the light remains on, some common reasons could be:

  • Incorrect descaling process: If the descaling process is not followed correctly, the machine might not be thoroughly cleaned, leaving the descale light on.
  • Wrong descaling solution: Using anything other than the recommended Keurig Descaling Solution could make the process ineffective.
  • High mineral content in your water: Water from certain areas may have a higher mineral content or ‘hardness‘. These minerals might not be completely removed in one descale cycle, and the descale light will remain on. If this is the case, you may need to repeat the descaling process.
