Insufficient steam pressure in the system automatic cappuccino maker Krups coffee machines often result in the formation of liquid foam instead of a dense milky head. This technical problem can be caused by clogged milk collection tubes, air getting into the line, or scale on the thermoblock, which requires an immediate check of the tightness of the connections and a decalcification procedure.
Users selecting Krups with an integrated milk system, they must take into account that the automatic unit requires more careful maintenance compared to a manual panarello. Unlike semi-automatic models, here the emulsification process occurs inside the housing, which makes the condition of the internal valves and pump critical.
If you notice that cappuccino maker started to “spit” or give out milk in jerks, the first step should be a visual diagnosis of the removable elements. Often the reason lies in the lid of the milk container not being tightly closed or in the use of a product with the wrong fat content, which disrupts the aerodynamics of suction.
How the Krups automatic milk system works
Automatic cappuccino maker in brand coffee machines Krups operates on the Venturi principle, where a jet of steam or hot water creates a vacuum that draws milk from the tank. Mixing takes place in a special chamber, after which the finished drink is served in a cup. The quality of the foam directly depends on the serviceability nozzles and cleanliness of internal channels.
The system design typically includes a removable container, a collection hose, and a mixing unit located inside the machine body. In modern models of the series EA81 or EA89 “One Touch” technology has been implemented, allowing you to prepare cappuccino or latte macchiato at the touch of a button. The electronics automatically regulate the sequence of espresso and frothed milk.
⚠️ Attention: Using expired milk or adding foreign liquids (syrups, water) to the reservoir may cause irreversible damage automatic cappuccino maker and lead to souring of the product inside the tubes.
For stable operation of the mechanism, it is important that the milk temperature is in the range of 4-6 degrees Celsius. Milk that is too warm will not be able to form a stable emulsion, and the foam will quickly settle, turning into a regular liquid. A cold product provides better air saturation when passing through mixing chamber.
Technical nuances of pump operation
A separate mini-pump operates inside the system or the pressure of the main pump is used through a valve group. In some budget models, milk is withdrawn due to steam pressure, which makes the absence of scale on the heating element critical.
Criteria for choosing a model with an integrated cappuccino maker
When purchasing a coffee machine Krups with automatic preparation of milk drinks, you should pay attention to the type of used heating element. The thermoblock allows you to reach operating mode faster, but requires high-quality water treatment, while boiler systems are more inert, but more stable in temperature conditions.
An important parameter is the presence of a function for adjusting the strength of the drink and the serving size. Automatic cappuccino maker should be able to adjust the degree of foam so that the user can choose between dense foam for a cappuccino and thin milk for a latte. Some models have a digital display to make these settings easier.
- 🥛 Container volume: The capacity of the milk tank varies from 0.5 to 1 liter, which is important for large families or offices.

Once a week, it is recommended to deep clean the removable parts of the container. They should be washed with warm water and a mild detergent, rinsing thoroughly to remove the chemical smell. Milk hose should be checked for elasticity and the absence of cracks through which air can be sucked in.
☑️ Daily care of the coffee machine
To remove fatty deposits that are not washed off with water, you can use special tablets for cleaning milk systems. They dissolve in water, and the solution is passed through cappuccino maker in steam or hot water mode. This helps break down protein contaminants inside the node.
⚠️ Attention: Never leave milk in the container overnight or over the weekend. The product quickly sours at room temperature, which will lead to an unpleasant odor and require difficult disassembly automatic node for cleaning.
Diagnosis of cappuccino maker malfunctions
If the coffee machine Krups milk has stopped frothing, the first reason is often a loss of tightness. Air may be sucked in through a loose container or a damaged O-ring. In this case, instead of foam, just hot milk or steam will be blown out of the spout.
Another common problem is a clogged outlet. cappuccino maker curdled protein or scum. To fix the problem, you need to remove the feed spout and soak it in warm water. The use of sharp objects for cleaning is strictly prohibited, as this can damage the calibrated hole.
- 🔇 Noisy operation: A loud sound when milk is drawn may indicate that the tube is touching the bottom or side of the container.
- 💧 Leaks: the appearance of a puddle under the car is often associated with an overflow of the pan or a violation of the tightness of the connections milk block.
- 🌡️ Low temperature: If the milk is served cold, the heating element may need to be decalcified or the temperature sensor replaced.
In cases where simple cleaning methods do not help, professional diagnostics may be required. solenoid valves. They are responsible for switching the flow of water and steam, and their sticking leads to incorrect operation of the entire milk system.
Use only fresh pasteurized milk with a fat content of 2.5-3.5%. Skim milk does not froth well, and milk that is too fatty can produce a heavy, unstable foam.
Decalcification procedure to maintain steam pressure
Scale is the main enemy of any coffee machine, and model Krups with automatic cappuccino maker no exception. Salt deposits narrow the passageways, reducing the steam pressure needed to emulsify the milk. Regular decalcification extends the life of the thermoblock and pump.
The descaling process starts automatically when the corresponding indicator lights up or manually through the service menu. It is necessary to use only special liquid products recommended by the manufacturer. Vinegar or citric acid can damage rubber seals and plastic parts hydraulic system.
During the descaling cycle, the machine will alternately supply solution and clean water. It is important to strictly follow the instructions on the display screen and not interrupt the process, even if it takes 20-30 minutes. Interruption may cause acid residues to remain inside. heating element.
⚠️ Attention: After completing the decalcification program, be sure to rinse the water tank and run 2-3 cycles of hot water without coffee. This ensures complete removal of cleaning agent residues from internal highways.
