The descaling light on my De'Longhi Magnifica stays on

You've just descaled your De'Longhi Magnifica, but the descaling light stays on. In this article, we explain what may cause this. We'll also explain how to solve the problem. You can use this manual for the De'Longhi Magnifica ECAM 20.110.B, ECAM 21.117.B, ECAM 22.110.B, and the ECAM 22.110SB.

Descale the right way

If the descaling light of your De'Longhi Magnifica stays on, the descaling process isn't finished yet. To completely finish the descaling process of your De'Longhi Magnifica, follow the steps below. After you finish these steps, you can enjoy a nice cup of coffee.

  • Step 1. Fill the water tank
  • Step 2. Start the descaling process
  • Step 3. Activate the rinse process
  • Step 4. Refill the water tank
  • Step 5. Repeat the process

Step 3: activate the rinse process

  1. Completely open the steam knob. Turn the knob to the 'i' position in 1 fast movement.
  2. Water now runs from the machine. The machine stops by itself when the water tank is empty. This process takes about 30 minutes.
  3. Because the water tank slowly drains, the light of the water tank lights up. You don't have to do anything.
  4. Close the steam knob again. You do so by turning the knob to the 'o' position in 1 fast movement.

  4. The water runs from the machine. The coffee machine stops by itself when the water tank is empty.
