Regular maintenance of coffee equipment is the key to the stable taste of your espresso and the long life of the equipment. Over time, limescale accumulates inside the boiler and pipes, and coffee oils get stuck in the holder and begin to taste bitter. If you notice that the drink has become less aromatic and the cooking process has slowed down, it’s time to act.
Many owners carob coffee makers They mistakenly believe that simply rinsing the parts with water is enough. However, deep cleaning requires the use of special means and adherence to a certain sequence of actions. Ignoring this process may result in damage to the heating element or deterioration in steam quality.
In this article we will look at how to clean a carob coffee maker effectively and safely. You will learn about the differences between descaling and backflash, and also get answers to frequently asked questions about caring for your model.
Why you need to clean your coffee maker regularly
The water used to make coffee contains mineral salts. When heated, they precipitate, forming hard deposits known as scale. This layer has low thermal conductivity, which is why heating element (heating element) is forced to work with increased load, which leads to overheating and eventual breakdown.
In addition, microparticles of ground coffee remain in the holder and brewing group. Over time, the fats contained in the grains oxidize and become rancid. Coffee oils can overpower the subtle notes of fresh grain, making the drink flat and unpleasant.
⚠️ Attention: Using hard water accelerates the formation of scale by 3-4 times. If you do not use jug filters, decalcify more often than the time recommended by the manufacturer.
Regular flushing allows you to maintain the pressure in the system at an optimal level. Valves and tubes clogged with salt deposits cannot provide the necessary 9 bar for proper extraction. The result is not a dense espresso with creamy foam, but a watery liquid.
Preparing for the cleaning procedure
Before starting work, it is necessary to prepare the workplace and the necessary accessories. You will need a decalcifying agent (special liquid or powder), a container to collect water and a soft cloth. Also remember to unplug the device and let it cool completely.
There are two main types of cleaning: descaling the internal system (decalcification) and cleaning the brew group of coffee oils (backflush). For the first type, acidic solutions are used, for the second - alkaline tablets. Don't get confused these products, since their chemical composition is different.
Prepare clean drinking water in advance. After chemical treatment, you will have to run clean water through the system several times to flush out any remaining chemicals. If you have a model with a built-in tank, make sure it is completely empty before adding the cleaning solution.
Stages of decalcification of the internal system
The descaling process requires care. First, dilute the decalcifying agent in water according to the instructions on the package. Usually the proportion is 1 part product to 10-20 parts water, but for specific models DeLonghi or Breville dosage may vary.
Pour the prepared solution into the water tank. Turn on the coffee maker and wait until it returns to operating mode. Open the steam supply tap (cappuccino maker) and release a little liquid so that the solution enters the steam-forming path. Then close the tap.
☑️ Checklist before starting decalcification
Allow the solution to sit inside the system for about 15-20 minutes so that the acid begins to dissolve the deposits. After this, turn on the flow of water through the holder (without coffee) and the steam tap alternately until the tank is empty. This will help clean all internal channels.
The most important step is rinsing with clean water. Rinse the tank thoroughly, add fresh water and run it through the system twice. This is necessary so that there is no acidic taste left in the drink. If you smell a sour steam, repeat the procedure again.
Cleaning the holder and brewing group
The holder (horn) requires special attention, since it is in it that the brewing takes place. Remove the coffee basket and soak the metal parts in hot water and detergent. Use a soft brush to remove stuck coffee particles from the filter mesh.
For deep cleaning of oils, the backflash method is used. If your coffee maker supports this function, insert a blind basket (without holes) or a special disk into the holder. Place a coffee machine cleaning tablet in there.
| Type of pollution | Cleaning agent | Treatment frequency | Risk of being ignored |
|---|---|---|---|
| Scale (lime) | Acidic solution | Once every 2-4 months | Broken heating element, noise during operation |
| Coffee oils | Alkaline tablets | Once every 1-2 weeks | Rancid taste of coffee |
| Mechanical dust | Water and brush | Daily | Clogged mesh, poor drainage |
| Fatty deposits on the steamer | Damp cloth | After each use | Milk solidification, bacterial growth |
Turn on the water flow for 10 seconds, then turn off for 10 seconds. Repeat the cycle 5-7 times. The pressure of water with dissolved chemicals will break through old oil deposits that cannot be removed by regular washing. After the procedure, be sure to rinse the holder with clean water.
Caring for the cappuccino maker and external elements
The steam wand (cappuccinatore) often becomes clogged with curdled milk. Immediately after frothing the milk, wipe the tube with a damp cloth and blow through it with steam. If the milk has already dried, remove the removable cap (if there is one) and soak it in warm water.
Wipe the outer parts of the case with a soft, slightly damp cloth. Do not use abrasive sponges or aggressive household chemicals, as they may damage the stainless steel or plastic coating. For polishing, use special sprays for household appliances.
Can I use citric acid?
Citric acid is a popular folk remedy, but professionals treat it with caution. Acid crystals may not completely dissolve and damage rubber seals or plastic valves. It is better to use specialized products with corrosion inhibitors that are guaranteed to be safe for the coffee maker’s foodways.
Pay attention to the rubber seals around the brewing group. Over time, they may crack or lose elasticity. Wipe them with a damp cloth after each cleaning to remove coffee dust, which acts as an abrasive.
Typical maintenance errors
One of the most common mistakes is using vinegar. Acetic acid has a pungent odor that is very difficult to remove from porous materials and rubber bands. In addition, it may be too aggressive for some metal alloys used in boilers.
Another mistake is ignoring the drip tray. Water with coffee residues accumulates in it, which creates an ideal environment for the growth of mold and bacteria. Wash the tray and grate with hot water and detergent at least once a week.
⚠️ Attention: Never turn on the coffee maker without water in the tank, even for a short time. This can instantly damage the heating element and pump.
Do not attempt to disassemble the device yourself if it is under warranty. Internal components are under tension and pressure. For complex repairs, it is better to contact an authorized service center.
Treatment Frequency and Maintenance Chart
The maintenance schedule depends on the hardness of the water and the intensity of use of the coffee maker. If you're making 5-10 cups a day, the intervals between cleanings should be shorter. In offices where the workload is higher, preventive maintenance is carried out monthly.
Set a reminder on your phone immediately after cleaning. This will help you remember about the next procedure after the required period of time.
Keep a maintenance log. Record decalcification and filter replacement dates. This will help you track the status of your device and plan expenses for consumables. Regularity is the key to the long life of your coffee maker.
How do you know when it’s time to descale your coffee maker?
Main signs: the device has become louder, the heating process has increased, a weak stream of steam comes from the spout of the cappuccino maker, and the taste of the coffee has become less intense. A white sediment may also appear at the bottom of the cup.
Can the holder be washed in the dishwasher?
Most manufacturers do not recommend washing the holder in the dishwasher. Aggressive detergents and high temperatures can damage the non-stick coating of the basket and deform the handle. It is better to wash by hand with warm water.
What should I do if my coffee still tastes bitter after cleaning?
If decalcifying and backflushing don't help, the problem may be the grind size (too fine) or the water temperature. It is also worth checking the freshness of the beans - old beans often give off bitterness, regardless of the cleanliness of the machine.
Do I need to change the filter in the jug when cleaning?
Yes, the carbon filter jug has a limited resource. If you carry out decalcification, it means that the filter can no longer cope with hardness salts. Replace the cartridge immediately after finishing the rinsing procedure with clean water.
Is it dangerous to leave the solution inside the coffee maker overnight?
Strongly not recommended. Prolonged exposure of metal and rubber parts to acid can lead to corrosion and destruction of seals. Follow the exposure time specified in the cleaning product instructions (usually 15-30 minutes).
