- Running the Descaling Cycle:
- Start the descaling cycle according to your machine’s instructions (usually by pressing the brew button). The machine will run the descaling solution through its system.
- Allow the machine to run until the water tank is empty.
- Rinsing the Machine:
- Remove the descaling solution from the collection container and empty the water tank.
- Rinse the water tank thoroughly with fresh water.
- Fill the water tank with fresh water.
- Repeat the descaling cycle process (steps 3 and 4) at least twice with fresh water to thoroughly rinse the machine and remove any remaining descaling solution or vinegar odor.
- Completing the Descaling Process:
- After the final rinse cycle, empty the water tank and refill it with fresh water.
- Reattach the capsule container and drip tray.
- Your Nespresso machine is now descaled and ready to use.
Common Mistakes to Avoid
- Using Incorrect Descaling Solution: Always use DeLonghi’s official descaling solution or a properly diluted white vinegar solution. Avoid other cleaning products that could damage the machine. Never use citric acid.
- Skipping the Rinsing Process: Thorough rinsing is crucial to remove all traces of the descaling solution, which can affect the taste of your coffee.
