Preparation for Descaling
Before starting the descaling process, ensure your coffee machine is turned off and cooled down. Refer to your specific coffee machine's instruction manual for any model-specific preparation steps.
Required Items
- DeLonghi EcoDecalk solution
- Fresh water
- A large container (at least 1 liter capacity) to collect the descaling solution.
- Your coffee machine's instruction manual.
Descaling Procedure
The following steps provide a general guide for descaling. Always consult your coffee machine's specific instruction manual for detailed, model-specific descaling instructions, as procedures can vary significantly between models.
- Empty Water Tank: Empty the water tank completely and remove any water filters or softeners.
- Prepare Solution: Pour one dose (125 ml) of DeLonghi EcoDecalk solution into the water tank.
- Fill with Water: Fill the water tank with fresh water up to the indicated descaling level (usually 1 liter or as specified by your machine's manual).
- Position Container: Place a large container (at least 1 liter capacity) under the coffee spout and steam wand (if applicable) to collect the descaling solution.
- Initiate Descaling Cycle: Turn on your coffee machine and initiate the descaling cycle as per your machine's instructions. This often involves pressing a specific button or navigating a menu.
- Complete Cycle: Allow the machine to complete the descaling cycle. This may involve intermittent dispensing of the solution and can take some time.
- Rinse Water Tank: Once the descaling cycle is complete, empty and thoroughly rinse the water tank with fresh water.
- Perform Rinse Cycles: Fill the water tank with fresh, clean water. Run several rinse cycles (usually 2-3) through the machine to ensure all descaling solution residue is flushed out. Use the large container to collect the rinse water.
- Clean Drip Tray: Empty and clean the drip tray.
- Ready for Use: Your machine is now descaled and ready for use.

Maintenance and Descaling Frequency
Regular descaling is crucial for maintaining the performance and longevity of your coffee machine. The frequency of descaling depends on your water hardness and how often you use the machine.
- For optimal performance, descale your machine every 2-3 months, or as indicated by your machine's descaling alert.
- Using DeLonghi EcoDecalk ensures effective removal of limescale without damaging internal components.
- Always use fresh, clean water for daily operation and rinsing cycles.
Troubleshooting Common Issues
If you encounter issues after descaling, consider the following:
- Machine still indicates descaling needed: Ensure you completed all rinse cycles. Some machines require a specific sequence to reset the descaling indicator. Refer to your machine's manual.
- Poor coffee flow or taste: This could indicate residual descaler. Run additional rinse cycles with fresh water until the water runs clear and taste is normal.
- Machine not starting descaling cycle: Verify that the water tank is filled correctly with the solution and that the collection container is in place. Check your machine's manual for the correct procedure to initiate descaling.
- Error messages: Consult your coffee machine's manual for specific error codes and their solutions.
