Perform a Manual Descaling
- Fill the water reservoir with a descaling solution (e.g., De’Longhi EcoDecalk).
- Place a container under the coffee and steam outlets.
- Follow your machine’s specific descaling cycle instructions—usually, pressing and holding certain buttons to start descaling.
- Run the cycle until the reservoir is empty, then rinse thoroughly with fresh water.
Reset the Descale Light
After descaling, reset the indicator light. Typically, this involves pressing and holding specific buttons (refer to your manual). For many models, holding the descaling button for a few seconds will clear the warning.
Verify and Finalize
Refill the water reservoir with fresh water, turn the machine on, and check if the descale light is off. Run a test brew to ensure proper operation.
Prevent Future Buildup
- Use filtered water to reduce mineral deposits.
- Descale regularly, as recommended (usually every 2-3 months).
- Consider replacing the water filter periodically.
