The lime light on my DeLonghi Magnifica stays on

You have just descaled your Delonghi Magnifica, but the descaling light stays on. Very annoying. In this article, I explain why this might be and, more importantly, how to solve this problem. Use this manual with the De'Longhi Magnifica ECAM 20.110.B, ECAM 22.110.B, and the ECAM 22.110SB.

Why does the descaling light stay on?

If the descaling light of your Delonghi Magnifica remains on, the descaling procedure has not been completed properly. It may be that you've skipped a step, or that you haven't done it correctly. For example, it's possible that you have put too little water into the water reservoir during the descaling process.

How do I correct the problem?

To properly complete the descaling procedure of your Delonghi Magnifica, follow the steps below. After completing these steps, you'll enjoy a good cup of coffee again.

Fill the water tank up to level B

Fill the water tank with tap water up to level B.

Step 1: Switch on the coffee machine by pressing the on button.

Step 2: Remove the filter from the water tank (if present).

Step 3: Fill the water tank with tap water, up to level B. This is indicated with a 'B' on the water tank. Put the water tank back in the machine.

Step 4: Press the descaling button for 5 seconds until the descaling light stops flashing. The light is now on without blinking. This means that the coffee machine is in the descaling mode.

Step 5: Place a large jug or container under the steam pipe and under the coffee spout (from which the coffee normally flows).

Step 6: Open the steam knob all the way. You do this by turning the knob towards the "I" in one smooth motion. Water now flows from the machine. The coffee machine stops automatically when the water tank is completely empty. This takes around 30 minutes, including short intervals.

Step 7: Because the water tank slowly empties itself, the water tank light turns on. You don't have to do anything with this.

Step 8: Fully close the steam knob again. You can do this by turning the knob towards the "O" in one smooth motion.

Fill the water tank up to 'MAX'

Step 10: Open the steam knob all the way. You do this by turning the knob towards the "I" in one smooth motion.
