3. Usage Instructions (Descaling Process)
Always refer to your specific coffee machine's instruction manual for detailed descaling procedures. The following is a general guide for using De'Longhi EcoDecalk:
3.1. Preparation
- Ensure the coffee machine is turned off and cooled down.
- Empty the water tank and remove any coffee filters or pods.
- Pour the recommended amount of De'Longhi EcoDecalk into the water tank. For most De'Longhi machines, this is typically 100 ml of descaler.
- Fill the water tank with fresh water up to the descaling level indicated in your machine's manual, or to the maximum level if no specific descaling level is mentioned.
- Place a large container under the coffee spout and steam wand (if applicable) to collect the descaling solution.
3.2. Descaling Cycle
- Turn on your coffee machine.
- Initiate the descaling cycle according to your machine's specific instructions. This usually involves pressing a dedicated descaling button or following a menu prompt.
- Allow the machine to complete the descaling cycle. The machine will typically dispense the solution in intervals through the coffee spout and/or steam wand.
- Monitor the collection container and empty it as needed to prevent overflow.
3.3. Rinsing Cycle
- Once the descaling cycle is complete, empty and thoroughly rinse the water tank.
- Fill the water tank with fresh, clean water up to the maximum level.
- Place the empty collection container back under the spouts.
- Initiate a rinsing cycle (or several, as recommended by your machine's manual) to flush out any remaining descaling solution.
- Repeat the rinsing cycle with fresh water until the water tank is empty, ensuring all descaler residue is removed.
- Your coffee machine is now descaled and ready for use.

4. Maintenance
Regular descaling is crucial for the optimal performance and lifespan of your coffee machine. The frequency of descaling depends on your water hardness and how often you use the machine. Most manufacturers recommend descaling every 2-3 months, or when your machine indicates it's necessary.
Using De'Longhi EcoDecalk regularly helps prevent the buildup of limescale, which can lead to:
- Reduced water flow.
- Lower coffee temperature.
- Increased energy consumption (up to 30%).
- Impaired coffee flavor.
- Potential damage to internal components.
