Any automatic coffee machine Philips sooner or later faces the problem of accumulation of coffee oils. This is an inevitable process that directly affects the quality of your morning espresso. Over time, a sticky coating forms on the internal parts, which makes the drink bitter and can cause an unpleasant odor. Regular equipment hygiene - this is not just a recommendation, but a necessity to extend the life of the device.
Many owners ignore the first signs of contamination, relying on automatic washing programs. However, a standard rinse cycle is not able to dissolve old fat deposits. You'll need a more in-depth approach that includes manual cleaning of key components. Only comprehensive service guarantees that your Saeco or Philips will delight you with the perfect taste for years.
In this article we will look at all the stages of removing coffee oils, from simple steps to deep cleaning of the brewing unit. You will learn which products are truly effective and which ones can damage the plastic or seals. Proper care requires knowledge of the design nuances of your particular model.
Why coffee oils are formed and why they are dangerous
Coffee beans contain natural fats that are released during the grinding and brewing process. At high temperatures and pressure, these substances oxidize and polymerize, forming a viscous substance. It settles on the walls of the brewing unit, in the brewing chamber and in the outlet spout. Over time, this layer hardens, turning into a crust that is difficult to remove.
The danger of such plaque is not only the deterioration of taste. Hardened oils can block the movement of mechanical parts, increasing the load on the engine. Brewing unit stops closing tightly, which leads to water leaking past the coffee. As a result, you get a weak drink and a puddle on the tray.
In addition, oxidized fats are an ideal breeding ground for bacteria and mold. Even if you use fresh beans, old residue will spoil the flavor. Regular disinfection Helps avoid the appearance of off-flavors.
⚠️ Attention: If you notice that the coffee stream has become sluggish, and the drink itself has acquired a sour or rancid hue, this is a sure sign that the system requires immediate cleaning of oils.
Ignoring the problem can lead to costly repairs. Mechanical parts, such as the brewing unit drive gears, may simply jam. Therefore, prevention is always cheaper than replacing components.
Oxidized coffee oils are the main cause of 80% of brewing mechanism failures in automatic coffee machines.
Necessary tools and tools for maintenance
For quality cleaning, you will need the right set of tools and chemicals. You should not use household dishwashing detergents, as they create a lot of foam that is difficult to wash out of the internal channels. Specialized cleaning tablets designed specifically to dissolve coffee fats without harming food plastics.
You will need soft brushes, sponges and a container of warm water. Harsh abrasives can scratch the Teflon coating of the infuser, causing plaque to form even faster. Taking good care of surfaces is the key to durability.
- 🧼 Special cleaning tablets for coffee machines (remove oils and disinfect).
- 💧 Liquid for decalcification (removing scale, which is often paired with oils).
- 🖌️ Soft brush or brush for cleaning hard-to-reach places.
- 🧽 Microfiber for wiping external and internal surfaces.
Using original chemistry Philips or certified analogues guarantees the safety of seals. Cheap products may contain aggressive alkalis, which will make the rubber bands brittle.
Always use warm water (around 40°C) to dissolve cleaning tablets - this speeds up the chemical reaction and improves the result.
Preparing the coffee machine for cleaning
Before starting any work, the device must be properly prepared. First, unplug the coffee machine. This is a critical safety step as you will have to remove the internal mechanisms and accidentally starting the motor could cause injury.
Let the machine cool down if it has just been running. Hot elements can cause burns, and temperature changes upon contact with water sometimes lead to microcracks in the plastic. Once cooled, remove the drip tray and pulp container.
Wash the tray and grid thoroughly under warm water and regular detergent. This is where water and coffee residue accumulate, which turns into sticky mud when it dries. A clean tray is the basis for the hygiene of the entire system.
☑️ Preparing for cleaning
Make sure your work area is well lit. You will have to carefully inspect the parts for residue. Prepare all cleaning supplies in advance so you don't have to worry about the process.
Manual cleaning of the brewing unit from oils
The heart of your coffee machine is the brew group. This is where the magic of turning ground grain into drink happens, and where most of the oils settle. In cars Philips and Saeco this unit is usually removable, making maintenance much easier.
To remove the unit, open the service door. On some models, you must first turn the adjustment lever to the unlock position. Gently pull the block towards you, holding it by the side handles. Do not use excessive force; the mechanism should come out smoothly.
Rinse the block under running warm water. Do not use hot water as it may warp the plastic parts. Thoroughly rinse away any visible coffee residue. To remove oils, use cleaning tablets: dissolve the tablet in water and soak the block for 15-20 minutes, or wipe with a concentrated solution.
| Block element | Type of pollution | Cleaning method | Frequency |
|---|---|---|---|
| Filter mesh | Fine dust, oils | Soaking, soft brush | Once a week |
| Pistons | Old cake, fat | Wiping with a sponge | Once a week |
| Side walls | Scale, plaque | Washing with water | Daily |
| Seals | Sticky coating | Wet wipe | Once a month |
Pay special attention to the mesh filter. Its cells are often clogged with fine coffee dust mixed with oils. Use a soft brush to gently clean out the holes without damaging the mesh.
After cleaning, be sure to lubricate moving parts and seals with silicone grease, if recommended by the manufacturer in the instructions for your specific model. This will ensure silent operation and tightness.
Cleaning the brew chamber and outlet spout
After removing the brewing unit, a niche remains inside the case - the brewing chamber. This is a hidden place where forgotten coffee particles and mold often accumulate. Wipe the walls with a damp, well-wrung cloth. Water should not get in inside the machine body, onto electronic components.
The outlet spout (dispenser) from which the coffee flows also requires attention. The finished drink passes through it, and the remaining oils oxidize here most quickly due to contact with air. Remove the removable part of the spout if your design Philips it allows, and rinse it.
To clean the internal channels of the spout, run the rinsing program without coffee. If the plaque is heavy, you can use a long brush, carefully moving along the inner walls. Do not use metal objects that could scratch the plastic.
⚠️ Attention: Never pour water directly into the hole where the infuser was placed. This may cause a short circuit and damage the electronics.
Check the condition of the rubber seals in the niche of the brewing unit. If they show cracks or severe wear, it is best to replace them. The tightness of the system directly affects the brewing pressure.
Automatic cleaning and decalcification of the system
In addition to manual cleaning, the coffee machine Philips equipped with automatic programs. The decalcification program removes scale but also helps to flush out remaining oils from the internal pipes and boiler. Run this procedure regularly using a special liquid.
There is also a deep cleaning mode using tablets. Unlike manual washing, this method affects the entire hydraulic system. The solution with the tablet passes through all channels, dissolving fatty deposits where the brush cannot reach.
Startup sequence (approximate):
Menu → Settings → Care → Cleaning tablets
Follow the instructions on the machine display. The process may take from 15 to 30 minutes. It is important to use full containers of clean water for rinsing after cleaning to avoid any residual cleaning product getting into the cup.
Is it possible to use citric acid instead of special products?
The use of citric acid or vinegar is not recommended by manufacturers. Acid can attack rubber seals and aluminum boiler components, causing corrosion and leaks. Special products have a buffer pH that is safe for coffee machine materials.
Once the cycle is complete, the machine typically goes into ready mode. Run 2-3 pours of hot water without coffee to make sure there is no chemical aftertaste.
Common mistakes when servicing coffee machines
Many users make common mistakes that ruin all care efforts. One of the most common is to use a dishwasher to wash the brewing unit. High temperatures and aggressive detergents in the dishwasher destroy the special lubricant and can deform the plastic.
Another mistake is ignoring the schedule for replacing water filters. If you are using pitcher filters or cartridges AquaClean, their untimely replacement leads to hard water entering the system. The scale binds to the coffee oils, forming a hard stone that is almost impossible to remove without disassembling the machine.
- 🚫 Washing the brewing unit in the dishwasher.
- 🚫 Using abrasive sponges and scrapers.
- 🚫 Use of household chemicals (dishes, glass detergents).
- 🚫 Trying to lubricate the block with edible oil (it will go rancid).
Also, do not try to lubricate rubbing parts with edible sunflower or olive oil. It quickly oxidizes, becomes sticky and only makes the problem worse. Use only food grade silicone grease.
The most expensive mistake is skimping on cleaning products, leading to replacement of the brewing unit, the cost of which is up to 40% of the price of a new coffee machine.
Regularity is the key to success. It is better to spend 5 minutes weekly on prevention than several hours dealing with the consequences of neglect.
FAQ: Frequently asked questions
How often should I do a complete oil cleanse?
It is recommended to deep clean the brewing unit once a week if you drink a lot of coffee (3-5 cups per day). For moderate use, once every two weeks is sufficient. Automatic cleaning with tablets should be started once a month or after every 200-300 drinks prepared.
Is it possible to wash the brewing unit under the tap?
Yes, it is possible and necessary. However, the water should be warm, not hot. The main rule is not to use detergents for daily rinsing, only for routine cleaning with tablets. After washing, the unit must be completely dry before reinstalling.
What should I do if my machine makes a strange sound after cleaning?
Check whether the brewing unit is installed correctly. If it is not inserted completely or is skewed, the mechanism will work with interference. Also make sure that all removable parts (spout, grill) are in place. If the sound persists, run a rinse cycle.
Is it harmful to leave the brewing unit wet?
Short term - no. But for long-term storage (for example, if you go on vacation), the unit must be thoroughly washed, dried and left outside the car. A humid environment encourages the growth of mold, which will then end up in the coffee.
