Regular maintenance of your coffee maker is not just a whim of the manufacturer, but a necessity to maintain the quality of your favorite espresso. If you notice that the drink has become less aromatic, a foreign taste has appeared, or the machine makes unusual sounds when operating, then it’s time to do some spring cleaning. Ignoring these signals can lead to serious damage, the repair of which will cost much more than timely prevention.
Modern models Philips equipped with smart warning systems that signal the need for descaling or lubrication. However, you should not rely only on indicators, since visual inspection and manual cleaning of internal mechanisms are often required more than once every six months. In this material we will analyze all the stages of caring for your coffee machine, from simple daily procedures to deep descaling.
Before you begin, make sure that the device is turned off and unplugged. This is a basic safety rule that cannot be ignored. Preparation of the work area is also important: you will need a soft cloth, warm water and possibly special products recommended by the manufacturer for your type of equipment.
Daily care and basic hygiene
Keeping your coffee machine clean starts with simple steps that need to be done after each use or at least once a day. The main enemy of high-quality coffee is the old remnants of coffee oils and dry cakes that remain in the waste tray and on the cappuccino maker. If you do not remove them in a timely manner, they begin to oxidize and impart bitterness to the freshly brewed drink.
Particular attention should be paid to the drip tray. It must be washed under running water using a mild detergent. Don't forget to wipe the platform where the cup sits, as spilled coffee quickly turns into a sticky substance that attracts insects and creates an unpleasant odor. To wipe external surfaces, use only a damp, well-wrung cloth.
Cappuccino maker or system LatteGo require immediate rinsing after preparing milk drinks. Milk is an ideal breeding ground for bacteria, and even a short stay of product residue inside the tubes can lead to mold. Flush the system with hot water immediately, without delaying the procedure.
Scratches on plastic will become a place for bacteria to accumulate, which will be almost impossible to wash.
Removing and cleaning the brewing unit
The heart of any automatic coffee machine Philips is the brewing unit (brew group). This is where the extraction process takes place and where coffee oils and fine bean particles most often accumulate. Regular washing of this unit is the key to long service life of the mechanism and excellent taste of coffee.
To remove the unit, open the service door on the front of the device. On some models, you may need to remove the waste tray and water tray first. Gently press the locking elements and pull the block towards you. Do not use excessive force; the mechanism is designed to be removed with a gentle movement.
Rinse the brewing unit under running warm water. Carefully rinse off any visible coffee residue from the strainers and moving parts. Strictly prohibited use detergents, soap or any household chemicals when cleaning the brewing mechanism itself, since its surface has a special food coating that is easily damaged.
☑️ Checklist for cleaning the brewing unit
After water procedures, leave the brewing unit to dry at room temperature. Do not use a hair dryer or other heating devices, as sudden changes in temperature may deform plastic parts. While the unit is drying, wipe the inside of the coffee machine with a damp cloth to remove any spilled coffee.
⚠️ Attention: Never lubricate the brewing unit with edible oil or fat! To lubricate the guides, use only special silicone grease intended for food production.
Descaling procedure (Decalcification)
Scale is hard deposits of calcium and magnesium salts that form when water is heated. Even if you use filtered water, it is impossible to completely avoid this process. Scale narrows the ducts, impairs heat transfer and causes the heating element to work with overload, which can lead to its burnout.
Coffee machines Philips have a built-in decalcification program. When the indicator lights up CALC CLEAN or a corresponding message on the display, you need to prepare a solution. Use only liquid descaling agent recommended by the manufacturer, or citric acid in the correct proportion if permitted by the instructions for your model.
Fill the water tank with solution to the maximum level. Start the cleaning program through the menu or button combination described in the user manual. The machine will alternately pump solution and clean water through the system. The entire process takes about 20-30 minutes and requires your presence to top up the water tank as needed.
| Parameter | Recommendation | Frequency |
|---|---|---|
| Water hardness | Use filtered water | Constantly |
| Descaling agent | Liquid decalcifier | By indicator |
| Solution temperature | Room | Every time you clean |
| Flushing the system | 2 full cycles with clean water | After decalcification |
After the program is completed, the machine will automatically switch to rinsing mode. Be sure to complete this step to ensure that any remaining acid is completely flushed out of the inner tubes. If you ignore rinsing, the first coffee you brew will have a sour taste.
What happens if you ignore descaling?
Scale can completely block thin water supply pipes, leading to overheating of the boiler and costly repairs. In addition, the coffee will be prepared at a lower temperature than necessary, and the taste of the drink will deteriorate significantly.
Maintenance of the LatteGo system and cappuccino maker
Owners of models with an automatic milk preparation system LatteGo have the advantage of no complicated tubes that need to be cleaned with a brush. The LatteGo design consists of two parts that are easy to disassemble and wash. However, there are some nuances here that you need to be aware of.
Disassemble the milk container into its component parts. Rinse each element thoroughly under hot water. Pay special attention to the mesh and the joints where milk clots can get stuck. You can use a soft brush to wash, but avoid sharp objects.
If you have a classic cappuccino maker with a tube, the maintenance process is more complicated. After each use, it is necessary to lower the tube into a container of clean water and turn on the steam supply to blow out the insides. Once a week, it is recommended to soak the removable part of the cappuccino maker in a special solution to remove milk fat.
To deep clean the cappuccino maker tube, use special tablets for dairy systems. Dissolve the tablet in warm water and run the solution through the system, then rinse thoroughly with clean water.
Don't forget to check the condition of the rubber seals on the milk block. Over time, they may lose elasticity or become covered with plaque that is difficult to wash off. Timely replacement of these small parts will prevent air leaks and ensure perfect foam.
Replacing the filter and adjusting water hardness
Using a softening water filter (AquaClean or equivalent) can significantly increase the intervals between descaling procedures. The filter not only purifies the water from impurities, but also reduces its hardness, which has a positive effect on the taste of coffee and the condition of the heating element.
Before installing a new cartridge, it must be activated. To do this, immerse the filter in a container of cold water and wait until all air bubbles come out. This usually takes about 5 minutes. If you skip this step, the filter may not work correctly or may even be damaged.
After installing the filter, be sure to inform the coffee machine about this through the settings menu. In models Philips this is done by selecting the number of the installed filter in the menu. The machine will reset the cup counter and begin counting the filter life again.
If you do not use a filter, it is important to correctly set the water hardness level in the device settings. To do this, use the test strip that comes with the kit, or find out the water hardness from your service provider. Incorrect setting will result in the machine requiring cleaning too often or, conversely, too rarely.
⚠️ Attention: The filter has a limited service life even when not used. Do not install a filter that has been stored unpacked for more than a few months, as its activated carbon may have lost its properties.
Frequent maintenance errors
Even experienced users sometimes make mistakes that can shorten the life of the coffee machine. One of the most common is using vinegar to remove scale. Acetic acid is aggressive to rubber seals and plastic parts inside the car, and also leaves a persistent odor that is very difficult to remove.
Another mistake is trying to lubricate the brewing unit with regular vegetable oil. Over time, this oil oxidizes, thickens and turns into a sticky mass that permanently blocks the mechanisms. Use only special food grade silicone based lubricants.
Some users try to wash the removable parts in the dishwasher at high temperature. Although some parts are labeled as dishwasher safe, prolonged heat treatment can cause micro-deformation of the plastic, which will compromise the seal of the joints.
Following proper maintenance increases the life of your Philips coffee machine by up to 10 years and guarantees consistently delicious coffee every day.
You should also avoid using distilled water. Despite the absence of salts, it is devoid of minerals that water hardness sensors need to work correctly. This may lead to erroneous readings and failures in the cleaning program.
Is it possible to use citric acid instead of a special product?
The use of citric acid is permissible only in extreme cases and in strict concentrations (usually 20-30 grams per liter of water). However, manufacturers recommend special products because they contain corrosion inhibitors and are better able to deal with specific types of deposits in coffee machines.
How often should the brewing unit be lubricated?
It is recommended to lubricate the guides of the brewing unit once every 6 months or after every 500th cup. The frequency depends on the intensity of use of the machine and the hardness of the water. If the block begins to move with difficulty or creaks, lubrication is required immediately.
What should I do if the scale indicator lights up after cleaning?
If the indicator does not go off after the end of the program, you may have interrupted the process or used an insufficiently concentrated solution. Try running the descaling program again, strictly following the instructions. Also make sure the tank is filled completely.
