Step 2: Complete a Descaling Cycle

  1. Fill the water tank with a descaling solution, such as the De’Longhi EcoDecalk Descaler or EcoDecalk Descaler, following the product instructions.
  2. Turn on the machine and initiate the descaling process as per the user manual.
  3. Follow the prompts until the cycle completes, ensuring all limescale deposits are dissolved.

Step 3: Reset the Descale Light

Once descaling is complete, you need to reset the indicator. On the Magnifica Evo:

  • Press and hold the ‘MENU’ button for about 5 seconds until the display shows ‘RESET.’
  • Use the arrow buttons to select ‘Descale’ and confirm with the ‘OK’ button.
  • The descale light should turn off, indicating the reset was successful.

Step 4: Troubleshoot Persistent Issues

If the light remains on after descaling and reset, check for software updates or try unplugging the machine for 10 minutes before restarting. If the problem persists, it could be a sensor issue or software glitch, and contacting customer support may be necessary.

Tips and Warnings

  • Always unplug the machine before maintenance or troubleshooting.
  • Use only recommended descaling products to avoid damage.
  • Perform descaling regularly based on water hardness and usage.
  • If unsure, consult the user manual or customer support for guidance.
