Identify the Cause of the Stuck Light
First, determine whether the descale light is stuck due to mineral buildup or a sensor malfunction. If your machine hasn’t been descaled recently, limescale may be causing the issue. Alternatively, a faulty water sensor can also trigger the light erroneously.

Perform a Descaling Cycle
- Fill the water reservoir with a mixture of equal parts water and descaling solution (preferably De’Longhi EcoDecalk Descaler for safety and effectiveness).
- Turn on the machine and select the descaling program if available, or follow the manual instructions for descaling.
- Run the cycle completely, ensuring the solution flows through the system.
- Rinse the water reservoir thoroughly and fill it with clean water.
- Run a rinse cycle to clear any residual descaling solution.
Reset the Descale Indicator
After completing descaling, reset the descale indicator. On most De’Longhi models, this involves pressing and holding specific buttons (refer to your user manual). For the Magnifica Evo Next, typically, holding the ‘R’ or ‘Menu’ button while turning the machine on resets the indicator.
Check the Water Sensor
If the light remains after descaling, inspect the water sensor for dirt or damage. Use a soft cloth to clean the sensor area gently. If the sensor appears damaged, contacting customer support or a professional repair service is recommended.
Tips and Warnings
- Always use the recommended descaling solution to prevent damage.
- Never ignore persistent lights; they may indicate deeper issues.
- Unplug the machine before performing any cleaning or sensor checks.
- Regular descaling (every 2-3 months) prolongs your machine’s lifespan.
