Regular maintenance of your coffee maker is not just a whim, but a necessity, which directly affects the quality of your morning drink. If you notice that the coffee has become less aromatic, the water flow has weakened, or foreign particles have appeared in the cup, then it’s time for spring cleaning. Internal mechanisms such as brewing unit and hydraulic system are constantly in contact with water and coffee oils, which over time oxidize and turn into a dense coating.
Ignoring this process can lead to serious damage to expensive components, in particular the pump or boiler. Saeco is a reliable brand, but even the most advanced equipment requires the attention of the owner. In this article, we will analyze all the stages of cleaning, from simple water rinses to deep decalcification, so that your car will serve for many years without complaints.
The most important thing is not to delay the procedure until obvious signs of a malfunction appear. Preventive cleaning takes much less time than subsequent repairs at a service center. Let's look at how to properly organize this process, using available tools and following the manufacturer's recommendations.
Why is regular system flushing necessary?
The water used to prepare espresso contains dissolved mineral salts. When heated in a boiler or thermoblock, these salts precipitate, forming limescale, or scale. This solid layer has low thermal conductivity, causing the heating element to take more time and energy to heat the water. Over time, this leads to overheating and failure of the heating element.
In addition to mineral deposits, coffee oils accumulate inside the machine. They are not washed off with ordinary water and, oxidizing upon contact with air, acquire a rancid taste. It is these oils that often cause freshly brewed coffee to have an unpleasant aftertaste of the old drink. Hydraulic system Saeco is designed in such a way that water passes through thin tubes, which are easily clogged with small particles of cake and scale.
⚠️ Attention: Using hard tap water without a softener filter accelerates the formation of scale by 3-4 times. This can lead to clogged valves and reduced pump pressure.
Regular flushing helps maintain hydraulic resistance normally, providing a stable pressure of 9-15 bar, necessary for proper extraction. If you do not remove deposits, the machine will become louder and the cooking time per serving will increase. In advanced cases, the automation can block the start, giving an error message about the need for maintenance.
Preparation for the procedure: necessary supplies and instruments
Before you begin, you need to prepare your workplace and purchase the right supplies. For coffee machines Saeco and other brands of the Philips group (which now owns the brand), it is critical to use specialized products. Common household chemicals, such as dishwashing detergent or vinegar, can cause irreparable damage to rubber seals and plastic parts.
You will need to purchase decalcifying liquid or tablets. Liquid is more convenient because it is easier to dose and dissolves faster, but tablets are often more economical and easier to store. You will also need a container for draining waste water with a volume of at least 1.5 liters, since during the flushing process the system will discharge water several times.
- 💧 Specialized descaling agent (liquid or tablets).
- 🧽 Soft sponge and brush for cleaning the brewing unit.
- 🧤 Disposable gloves to protect the skin of your hands from chemicals.
- 💧 Distilled or filtered water for final rinse.
Don't forget to prepare dry rags or paper towels. The process may be a little "wet", and it is better to protect the tabletop from splashes in advance. If your model has a removable water tank, make sure the inside is clean and there is no slimy residue on the sides.
If you don’t have a special decalcification agent on hand, you can use citric acid at the rate of 20-30 grams per 1 liter of water, but only in emergency cases. Specialty chemicals contain corrosion inhibitors that protect metal parts.
Removing and manually cleaning the brewing unit
The heart of any automatic coffee machine is the brew group. This is where the coffee tablet is formed and water flows through it. In cars Saeco This unit is usually removable, which greatly simplifies maintenance. Before starting work, be sure to unplug the device and wait until it cools down completely.
Open the service door, usually located on the side or front of the chassis. To remove the block, you need to press the latches (often they are red) and pull the module towards you. The movement should be smooth, without jerking. If the unit cannot be removed, check that the locking lever is lowered and that the service door is closed until it clicks.
After removal, you will see the remains of coffee grounds. They need to be carefully shaken into the trash bin. Then rinse the block under running warm (not hot!) water. Use a soft brush to remove dirt from hard-to-reach areas, but avoid using soap or detergents as the smell is very difficult to remove and will ruin the taste of the coffee.
| element | How to clean | Frequency |
|---|---|---|
| Brewing unit | Warm water, brush | Once a week |
| Cooking chamber | Wet wipe | After each block removal |
| Spout strainer | Brush, warm water | Once a month |
| Drip receiver | Detergent | As it fills up |
Inspect the rubber seals for cracks or wear. If they look OK, lubricate them with a food-grade silicone lubricant (such as Food Grade). This will extend their life and ensure the tightness of the system. After drying, install the block back until you hear a characteristic click.
☑️ Cleaning the brewing unit
Automatic descaling program
Modern models Saeco equipped with a built-in descaling program. It is recommended to start it when the corresponding indicator lights up or every 2-3 months, depending on the hardness of the water. Before starting, make sure the water tank is empty and the waste container and drip tray are clean.
Pour the decalcifying agent into the tank and add water to the maximum mark, observing the proportions indicated on the product packaging. Turn on the car. To enter the maintenance menu, you usually need to hold down a combination of buttons or press certain keys in sequence. The sequence may vary for different models, so refer to the instructions, but often it is a long press of the steam or menu button.
Typical sequence of entering the service menu:1. Turn off the machine.
2. Press the "Steam" button (or the button with the image of a kettle).
3. Without releasing the button, turn on the machine.
4. Release the button when the indicator flashes.
Once the mode is activated, the machine will begin the process. It will periodically supply water, then pause so that the chemistry has time to dissolve the deposits. The entire process can take from 15 to 30 minutes. During this time, do not turn off the device and make sure that there is room in the pan for the drained liquid.
⚠️ Attention: During the decalcification cycle, there is an aggressive chemical solution in the tank. Do not attempt to interrupt the process or open the reservoir lid to avoid getting burned or causing caustic liquid to spill.
After completing the main phase, the machine will ask you to rinse the system. You will need to empty the tray, rinse the reservoir with clean water, refill it and run the rinse phase. This is a critical step to remove any remaining acid from the inner tubes.
Rinsing the milk system (for cappuccino makers)
If your model Saeco equipped with an automatic cappuccino maker or milk jug (LatteGo), it requires daily care. Milk is an ideal breeding ground for bacteria, and even the slightest traces of it can lead to mold and unpleasant odors.
Remove the milk jug or tube immediately after use. Disassemble the structure into its component parts according to the instructions. Rinse all parts under warm running water. For deep cleaning, use a special liquid for dairy systems that removes fatty films.
- 🥛 Disassemble the cappuccino maker into all accessible parts.
- 🚿 Rinse the parts with warm water (up to 40°C).
- 🧼 Use a brush to clean internal channels.
- 💨 Blow the system with air or run an auto-cleaning program.
Many models have an automatic milk circuit rinsing function. After preparing the cappuccino, the machine will prompt you to start this cycle. Do not ignore this suggestion, as it is almost impossible to manually clean the thin silicone tubes inside the case.
What happens if you don't clean the milk system?
The remaining milk solidifies and sours inside the tubes. This causes bits of old curdled milk to end up in your coffee the next time you turn it on. In addition, bacteria can cause damage to the milk pump due to changes in the viscosity of the medium.
Cleaning the brew group and spout
Even after removing the brewing unit, the brewing chamber remains inside the housing. There may be coffee crumbs and drops of water left in it. Wipe the walls with a damp, well-wrung cloth. Pay special attention to the coffee spouts - through them the espresso pours into the cup.
Over time, the holes in the spout can become clogged with coffee oils, causing the stream to become uneven or split. For cleaning, use a special brush, which often comes with the machine. Carefully run it over the holes.
If the plaque is old, you can soak the removable spout (if the design allows) in warm water with a coffee machine cleaning tablet. This will help dissolve fat deposits without mechanical damage to the plastic. After the procedure, be sure to rinse the part thoroughly with clean water.
The cleanliness of the feed spout directly affects the formation of cream (foam) on the surface of the espresso. Clogged holes disrupt the pressure and turbulence of the flow, degrading the quality of the drink.
Common mistakes when servicing coffee machines
Many users, trying to clean their equipment as best as possible, make mistakes that nullify their efforts or damage the device. One of the most common is the use of aggressive chemicals not intended for coffee machines. High concentrations of citric acid or vinegar can corrode rubber gaskets, causing leaks.
Another mistake is lubricating the brewing unit with regular vegetable oil. This is absolutely not allowed! The oil quickly oxidizes, thickens and turns into a sticky mass that permanently blocks the mechanisms. You can only use food-grade silicone grease, and then in minimal quantities.
Also, do not wash the brewing unit in the dishwasher. High temperatures and aggressive dishwasher tablets deform plastic parts and destroy the special lubricant of the guides. Hand washing with warm water is the only safe option.
Can I use vinegar to descale my Saeco?
It is not recommended to use regular table vinegar. It has a pungent odor that takes a very long time to wash out of the system, and can damage rubber seals with frequent use. It is better to use special products designed taking into account the materials of coffee machines.
How often should you change your water filter?
The water filter jug (if compatible with your model) should be changed every 2 months or after preparing 50 liters of coffee. It depends on which comes first. Regular filter replacement significantly reduces the frequency of necessary decalcifications.
What should I do if my coffee turns sour after cleaning?
Most likely, there are residual decalcification agents left in the system. An additional rinse cycle with clean water is necessary. Also check if your coffee is ground too coarsely, as this can also give off a sour taste.
Do I need to lubricate the brewing unit after every cleaning?
No, no lubrication is required after each weekly flush. You only need to lubricate the guides if you notice that the block has become difficult to move, or after deep cleaning and complete drying. This is usually done once every 3-6 months.
