How To Fix A Delonghi Magnifica That Is Not Frothing Milk?

  1. Regularly clean all parts of the milk frother to prevent residue clogs.
  2. Ensure the ‘steam function’ is on and the steam dial is fully open.
  3. Inspect and replace the O-rings on the milk coupling mechanism if damaged.
  4. Use whole or semi-skimmed cow’s milk for optimal frothing.

The Milk Frother Is Clogged And Needs To Be Cleaned

Over time, the milk container can accumulate old milk residue. If not cleaned, this residue can clog the froth adjustment dial and the milk spout, reducing the machine’s performance and potentially affecting the taste of your beverages.

Proper and regular cleaning not only ensures the longevity of your milk container but also ensures that your milk remains fresh and frothy, ready to be used in your favorite beverages. Therefore, it’s essential to clean your milk container thoroughly after every use.

Here is the step-by-step process I used to clean my Magnifica milk frother:

  1. Take off the lid: Start by removing the lid from the milk container.
  2. Remove the milk spout: Next, take off the part from which the milk is poured, known as the milk spout.
  3. Detach the intake tube: This tube helps draw the milk. Make sure you remove it carefully.
  4. Pull off the froth adjustment dial: Turn the dial, which helps control the froth level, clockwise to the position labeled ‘insert’. After doing that, gently pull it off upwards.
  5. Wash all the parts: Once all components are separated, wash them thoroughly. Use hot water and light detergent. Make sure everything is clean, without any remaining milk.
  6. Dishwasher use: If you have a dishwasher, all these parts are safe to clean in it. Place them in the top section of the dishwasher for best results.
  7. Check the groove and hollow under the dial: Look under the dial for any stuck milk residue. If you find some, use a toothpick to gently scrape it out.
  8. Rinse the froth adjustment dial seat: Rinse the place where the dial attaches (dial seat) with running water.
  9. Replace the dial: Put the froth adjustment dial back into its place. Match it with the word ‘insert’ to ensure correct placement.
  10. Reattach the milk spout and intake tube: Put the milk spout and intake tube back to their original places.
  11. Place the lid back on: Finally, place the lid back on the milk container.

The Right Process

First, take a look at your machine’s control panel. Find the option for the ‘steam function’. This needs to be active for the frother to operate correctly, as it’s responsible for creating the steam necessary for frothing.

Next, locate the steam dial. This control is on the frother and adjusts the steam intensity. Make sure this dial is fully open, allowing maximum steam flow for optimal frothing.

Ensuring these two settings, steam function activation and steam dial position are correct.

An O-ring Might Be Damaged

O-rings are small circular gaskets that are used in appliances to prevent the leakage of fluids, like milk or water. In the Delonghi Magnifica coffee machine, they are primarily located on the spigots of the milk coupling mechanism.

Here’s a step-by-step process to inspect them for damage and replace them if needed:

Locating the O-rings

  1. Find the milk coupling mechanism on your machine. This is the part where the milk jug attaches.
  2. Identify the spigots – these are the small tubes that jut out from the milk coupling mechanism.
  3. You should see three O-rings: one on the top spigot (usually green), a second at the front of the bottom spigot (black), and a third at the rear (red). There should also be a clear groove halfway along the spigot, which should be free from obstructions.

Inspecting the O-rings

  1. Check each of the O-rings for damage. They should be smooth and flexible, not cracked, brittle, or deformed.
  2. If the O-rings are not in their correct locations or seem to be damaged, they will need to be replaced.

Replacing the O-rings

  1. O-rings can be removed by gently pulling them off the spigots. Be careful not to damage the spigots in the process.
  2. Replacement O-rings can usually be found at a hardware store, or you can order them from the manufacturer. Make sure to get the correct size. You might find it helpful to bring the old O-rings with you to ensure a correct match.
  3. To install the new O-rings, simply stretch them over the spigot and roll them down into the groove where the old O-ring sat.

Remember, it’s crucial to regularly check and replace the O-rings on your Delonghi Magnifica coffee machine. If these rings are not sealing properly, it could impact the machine’s ability to froth milk correctly. Regular maintenance and replacement of these small components can help ensure your coffee machine operates at its best.

Alternatively, you could also get an O-ring kit from Amazon:

Using The Right Milk

The milk frothing function on the DeLonghi Magnifica may not perform optimally if you opt for plant-based milk. For the best results, I recommend using whole or semi-skimmed cow’s milk that’s kept at around 40 degrees Fahrenheit (the usual refrigerator temperature).

Plant-based milk tends to be too thin for the frothing system that the DeLonghi Magnifica features.

The Frother Is Still Not Working

If you’re finding that your frother isn’t functioning correctly, or worse, not functioning at all (you don’t hear any sound when you try to turn it on) there’s a good chance it could be broken.

In such cases, the ideal course of action would be to get in touch with DeLonghi’s customer service team. If your machine is still covered under its warranty period, the company will typically offer to either repair the existing machine or send you a replacement unit at no additional cost.


In summary, a DeLonghi Magnifica not frothing milk can usually be solved through some straightforward measures. Regular cleaning, ensuring the correct settings, checking the integrity of O-rings, and using the right kind of milk can restore your machine’s frothing functionality.

However, if these steps don’t rectify the problem, don’t hesitate to reach out to DeLonghi’s customer service.
