Initial Checks Before Reset

  • Ensure the machine has completed a full descaling cycle.
  • Check for any remaining descaling solution in the water tank or internal components.
  • Make sure the water tank is properly seated and the machine is powered off.

Step-by-Step Reset Procedure

  1. Turn off the machine and unplug it from the power source.
  2. Empty and rinse the water tank thoroughly to remove any residual descaling solution.
  3. Refill the tank with fresh water and plug the machine back in.
  4. Turn on the machine and press the ‘Menu’ or ‘Settings’ button, then navigate to ‘Descale’ or ‘Reset.’
  5. Follow the on-screen instructions or hold the reset button for 5 seconds to clear the warning.
  6. If the light remains on, run a short rinse cycle to flush out any leftover descaling residue.

Deep Cleaning and Descaling

If resetting doesn’t work, perform a thorough descaling using a recommended descaler like the EcoDecalk. Follow the manufacturer’s instructions carefully to ensure all mineral deposits are removed.

Tips and Warnings

  • Always use the recommended descaler to avoid damaging internal parts.
  • Avoid using vinegar or citric acid unless specified, as they can harm your machine.
  • Regularly clean and descale to prevent the light from triggering frequently.
  • Consult the user manual for specific reset instructions for your model.
