Step 2: Reset the Descale Light

  • Turn on your machine and ensure it is ready.
  • Press and hold the ‘Menu’ or ‘Settings’ button (depending on your model) for about 10 seconds until the indicator resets.
  • If your model has a specific reset button or sequence, refer to the user manual.

Step 3: Check Water Hardness Settings

Incorrect water hardness settings can cause false descale alerts. Access the machine’s menu to verify and adjust the water hardness level according to your local water report or test strip.

Step 4: Inspect the Descaling Sensor

If the light remains stuck, the sensor that detects limescale buildup might be dirty or faulty. Carefully clean the sensor with a soft, damp cloth and ensure it is dry before testing again.

Additional Tips & Warnings

  • Always use recommended descaling products to avoid damaging your machine.
  • Do not attempt to bypass or disable the descaling alert, as it is crucial for machine health.
  • Perform descaling at least every 2-3 months, depending on water hardness.
