Operating the automatic coffee machine Krups is not only the pleasure of aromatic espresso every morning, but also responsibility for the technical condition of the device. The water used to prepare the drink contains calcium and magnesium salts, which, when heated, settle on the walls of the thermoblock and tubes, forming scale. Decalcification is a critical procedure, which, if ignored, will result in reduced pressure, overheating of elements and, ultimately, costly repairs.
Many owners wonder whether it is possible to use special solid products, so-called tablets, instead of liquid solutions. The answer is clear: yes, modern models Krups often support the use of tablet decalcifiers, which are convenient in dosage and storage. However, the process of their application has its own technological nuances, which must be strictly observed to maintain the warranty and operability of the unit.
In this article we will analyze all the stages cleaning the Krups coffee machine, starting from choosing the right product and ending with the final flushing of the system. You'll learn why you shouldn't use regular hardware store descalers and how to correctly interpret the display signals on your device's control panel.
The effect of scale on the operation of a Krups coffee machine
Scale is a hard limescale deposit that forms inside a hydraulic system. When water passes through the heating element, hardness salts crystallize and settle on hot surfaces. Over time, this layer becomes thicker, acting as a thermal insulator, causing thermoblock work with increased load.
The first signs that the system requires decalcification, changes occur during the brewing process. The coffee starts to dispense weaker, the stream becomes intermittent, and the preparation time for one serving increases noticeably. If you do not respond to these signals, the machine can completely block the cooking process, going into emergency mode.
In addition, lime deposits disrupt the extraction temperature regime. The water does not warm up to the required temperature, which directly affects the taste of the drink. Cleaning a Krups coffee machine with a tablet or liquid allows you to dissolve these deposits and restore factory operating parameters.
⚠️ Attention: The use of aggressive acids (pure citric acid, vinegar) is strictly prohibited by the manufacturer. They can damage the rubber seals and plastic parts of the internal line, which will lead to leaks.
Choosing a decalcification agent: tablets or liquid
The market for coffee care products offers two main formats: liquid concentrates and compressed tablets. Liquid products such as the original Krups F054, are considered classics and quickly dissolve in water. They are guaranteed to be safe for the materials used in the construction of coffee machines of this brand.
Cleaning tablets are a compressed powder that provides precise dosing. This eliminates the risk of error when measuring with the cap. However, when choosing a tablet form, it is important to make sure that it is compatible specifically with automatic coffee machines, and not intended for drip or carob models with a different operating principle.
When purchasing, pay attention to the labeling Ca300 or similar codes indicating compatibility with automation Krups. Some generic tablets may contain foaming agents that are difficult to flush out of the system without a special rinse cycle.
Original products often contain corrosion inhibitors that protect the metal parts of the boiler during the scale dissolution process. Using cheaper alternatives may save money in the short term, but there is a risk of damage hydraulic system It's not worth it.
Preparing the coffee machine for cleaning
Before starting any maintenance, the device must be properly prepared. First, make sure there is no old fluid left in the water tank. If the machine is on, turn it off and let it cool for 10-15 minutes.
Remove the water tank and rinse it thoroughly with warm water. Remove any residue from previous dressings to ensure the new descaling mixture works at peak efficiency. Also check the condition of the water softener filter if your model has one.
☑️ Preparation for decalcification
It is important to prepare a container to collect waste fluid. Drop tank volume for models Krups is usually about 1 liter, while a full cleaning cycle may require more space. It is recommended to empty the tray in advance or prepare an additional bowl to avoid dirty water overflowing onto the countertop.
If your model uses a Brita Intenza filter or an equivalent, it must be removed before starting the procedure. Filter elements are not designed for contact with acidic solutions and can be destroyed, clogging the system with crumbs.
Step-by-step instructions: how to start cleaning with a tablet
The process for starting the cleaning program may differ depending on the specific series of your coffee machine (for example, series Essenza, Vivario or EA). However, the general algorithm of actions remains similar for most automatic brand models.
First, dissolve the tablet in water. Unlike liquid products that are simply poured, the tablet must be placed in a tank and filled with water to a certain level, usually 500 ml or 1 liter, depending on the instructions for the specific product. Wait until completely dissolved, if necessary, or immediately replace the tank.
Next, you need to activate the decalcification mode. On many models, this is done by simultaneously pressing two buttons (often the espresso and lungo buttons) for 5 seconds. The indicators begin to blink, signaling the transition to service mode.
| Model Krups | Mode activation | Indication |
|---|---|---|
| Essenza Mini | Hold down the Lungo button (5 sec) | All indicators are flashing |
| Vivario | Menu -> Care -> Decalcification | Cleaning indicator light |
| EA81/EA82 | Care button -> Select program | Display text |
| Opal | Press 2 cups (5 sec) | Light pulsation |
Once activated, the machine will begin pumping solution through the system. This process can take from 15 to 30 minutes and occurs with pauses. Don't interrupt operation of the device during this time, even if it seems that it is idle. This is necessary for the chemical interaction of the product with scale.
Washing cycle and completion of the process
After the tank is empty, the machine usually signals the need for rinsing. This is a critical step as any remaining acid in the system will render the coffee undrinkable. Drain the contents of the tray and rinse it thoroughly.
Fill the tank with clean drinking water to the maximum. Reinstall it. The machine will automatically continue the cycle, passing clean water through the thermoblock and brewing unit. In some models, this stage must be started manually by pressing the cooking button.
It is recommended to repeat the wash cycle twice to ensure complete removal of the chemical. The outlet water should be absolutely clear and odorless. If you notice a sour taste or odor, repeat the rinse again.
