Step 2: Run the Descaling Cycle

  1. Turn on the machine and select the descaling program if available, following the specific instructions for your model.
  2. Allow the machine to run the full cycle, ensuring it dispenses the descaling solution through the system.
  3. Once completed, rinse the water tank thoroughly and refill with clean water.

Step 3: Flush the System

  • Run a few brewing cycles with clean water to flush out any remaining descaling solution.
  • This helps prevent taste contamination and ensures the machine is ready for use.

Step 4: Reset the Descale Light

  1. Press and hold the descaling button or follow your model’s specific reset procedure (check your user manual).
  2. Keep holding until the indicator light turns off or resets.
  3. If the light remains, turn off the machine, unplug it, wait 10 seconds, then plug it back in and try resetting again.

Tips and Warnings

  • Always use demineralized or filtered water to reduce mineral buildup.
  • Use recommended descaling products—avoid harsh chemicals or citric acid not specified for your machine.
  • Regularly replace your water filter to maintain optimal performance.
  • Consult your user manual for model-specific instructions on resetting.
