Miele Coffee Machine Is Not Frothing Milk (Solved!)


When it comes to enjoying a perfect cup of cappuccino or latte at home, you want the frother to be working and the quality of the froth can also make all the difference.

Miele’s built-in frother usually works great for making cappuccinos and lattes. However, like all appliances, it may encounter issues over time, often due to clogging or improper maintenance.

In this guide, I’ll cover everything you need to get your Miele milk frother back in top shape.

How To Fix A Miele Milk Frother That Is Not Working?

If your Miele milk frother isn’t working, it may be due to clogging in the milk container, the main dispenser unit, or the three-way connector. Clean all these components with water and a light detergent, ensuring any debris or mineral deposits are removed. Be careful to correctly reassemble the parts.

Another potential issue could be the milk hose touching the bottom of the milk container. Modify the hose by shortening it slightly or cutting a “Y” or inverted “V” shape at the end to improve air intake and milk uptake.

Lastly, the frother doesn’t work well with plant-based milk due to its thin consistency. For optimal performance, use whole or semi-skimmed dairy milk at around 40 degrees Fahrenheit. After cleaning and adjusting as necessary, run a milk-cleaning program before using the frother again.

Let’s dive into some more detail below.

The Milk Frother Is Clogged And Needs Cleaning

If you’ve started experiencing milk spitting and splattering despite running the cleaning programs, you may need to clean one or more of the three components: the three-way connector, the main dispenser unit, and the milk container.

Keeping the frothing system clean is crucial to its performance. In my experience, unclogging and cleaning will usually fix the issue.

Cleaning The Milk Container

Start by removing the cap of the milk container. Unplug the center spout, which is a tube that plugs into the center of the cap. You can clean this tube with water and light detergent.

Note that there is a small black colored washer on one end of the tube that can be removed and cleaned separately.

When reassembling, ensure the center of the tube fits directly into the hole in the middle of the cap. Press the washer inside until it’s flush with the inside surface of the cap.

Make sure the pointed end of the tube is facing downwards. If this end ever gets inside the cap, the system will stop working.

Cleaning The Main Dispenser Unit

To access the main dispenser unit, navigate to service maintenance on the machine’s interface and select ‘clean main dispenser’. Follow the prompts and wait until the dispenser descends fully.

After the dispenser stops moving, remove the whole cap. The dispensing unit will be behind this cap. Unplug it by pressing the lever on top and extract the unit from the machine.

Rinse it under cold water to flush out any potential debris. You may also use some light detergent to scrub any mineral deposits out.

Once cleaned, reinsert the dispenser unit and replace the cap, making sure it’s completely flat before pressing it down. Set the machine back into its normal position. The machine will automatically rinse itself to ensure cleanliness.

Cleaning The Three-Way Connector

If issues persist, you may need to clean the three-way connector. This is located at the back of the machine inside an enclosed box. Start by opening the back of the machine and identifying the box where the three-way connector is housed.

Press down and open the back cap, then unplug the connector from its original position. This might be a bit tight, so use caution.

It’s a good idea to take a photo or video before removing this three-way connection, so you know which tube goes into which connector point.

Rinse the connector under running water and light detergent until it’s free of debris and then place it back into the correct position.

If any debris is stuck inside, use the small brush provided to clean it out. Be careful not to pierce any of the tubing as the brush is quite sharp. Once you’re done, replace the cap and cover up the box.

After cleaning all these components, it is recommended to run a milk-cleaning program. This helps ensure that the machine is thoroughly clean. Now, your Miele coffee machine should be back to its best performance. You can try making another coffee and there should no longer be any milk spitting or splattering.

Adjusting The Milk Hose

Another potential solution is modifying the milk hose on your machine.

The hose might be extended too far, touching the bottom of the milk container. This can cause a blockage, preventing it from drawing up milk properly for frothing.

However, approach this solution with caution, as incorrect adjustments could lead to further issues.

Shortening The Milk Hose

You could consider shortening your milk hose. This modification could help if your hose is currently long enough to touch the bottom of your milk container. By shortening the hose, you might increase the air intake, which could lead to more effective frothing.

Bear in mind that this method comes with its own risks. Overly shortening the hose could lead to difficulties in milk suction, particularly when the milk container isn’t fully filled.

Cutting A “Y” Or Inverted “V” Shape

Alternatively, you might cut a “Y” or inverted “V” shape into the end of the milk hose. This method is designed to increase the surface area of the hose end, which may enhance milk uptake and prevent the hose from sealing against the bottom of the milk container.

Not Using The Right Type of Milk

The frothing mechanism of the Miele coffee machine may not function optimally with plant-based milk. To ensure the best performance, I recommended using either whole or semi-skimmed dairy milk at a temperature of approximately 40 degrees Fahrenheit (the typical refrigeration temperature).

Plant-based milk tends to be too thin in consistency for the efficient operation of the machine’s frothing system.


A well-functioning Miele milk frother depends on regular cleaning of key parts, proper adjustment of the milk hose, and the use of suitable milk.

Clean the container, dispenser, and connector regularly. Adjust the milk hose as needed for optimal performance. Use whole or semi-skimmed dairy milk for the best results.

Following these steps will help ensure a consistent, creamy froth for your beverages.
