Coffee brewing machines are not cheap and, in addition, require constant attention. Before you start using the device, you need to take the time and read the instructions in order to know in advance how the machine will behave if it is not taken care of.
In case of any problems, you can call a repair specialist to your home or immediately take the device to the service center if you do not have the means at home to wash the coffee machine. It is the contamination of the system by scale and congealed coffee oils that most often leads to the fact that the coffee machine does not pump water. This applies to both carob and capsule units.
Reasons why water does not flow in the coffee machine
Many users of coffee makers are surprised how often the system needs to be flushed; for example, the same brewer needs to once a week , and the filter is changed once every 2 months.
There are especially many problems with scale in units that consist of many moving parts, such as Delonghi. The more complex the mechanism, the faster it fails. To avoid the accumulation of calcium deposits, the system should be cleaned as described in the instructions. If the tap liquid contains a lot of salts, then cleaning is carried out more often, and it is better to use bottled water.
Other reasons why the Delonghi coffee maker does not supply water or it does not work well, what to do:
- The float sensor is stuck - take it to service.
- Clogged water purification filter - needs to be changed.
- Fluid leaks due to blockages, cracks in parts - buy new ones and replace them.
- The control panel does not work - take it to service, as the contacts are most likely oxidized.
If water does not flow into the Delonghi coffee machine, the cause may be a malfunction in the electronic unit. You can't do this without a board specialist.

Cleaning the coffee machine from coffee deposits
Modern automatic control equipment is equipped with special programs that monitor the condition of the device. The machine itself gives a signal about serious contamination. You shouldn't ignore him. It should be noted here that means for removing residues of coffee grounds and coffee oils are different from descaling agents.
Proper cleaning is done as follows:
- Place a cleaning tablet in the coffee loading compartment or in the brewing unit (look as indicated in the instructions).
- We turn on the unit.
- We launch the cleaning program.
- Pour the solution from the container (it should be foamy and whitish in color).
- Rinse the tank with clean water.
If you understand that you cannot cope with the care of the coffee machine on your own, call Remontano by phone. Our specialists will quickly put your equipment in order.
Features of repair of capsule coffee makers
The Dolce Gusto capsule coffee machine does not supply water - most likely the outlet hole needs to be cleaned. All models of this company - Nescafe, Nespresso, Krups - have a very thin needle from which water pours onto the capsule and which pierces it.
Limescale can cement the needle when the coffee maker has not been turned on for a while. Some models have a special wire at the back that cleans the hole in the needle. After cleaning, you need to turn on the coffee maker again and check how the coffee machine pumps water. If over time the coffee starts to flow out more slowly, the system is clogged again.
If water does not flow thickly in your Krups, Nescafe or Nespresso Dolce coffee maker, you can do a general cleaning with citric acid - dilute 2 teaspoons in a glass of water and pour into a container. There is no need to insert a capsule. Wait until the cloudy liquid comes out.
Pressure gauge failure
Modern coffee machines are equipped with two pressure gauges - a pump and a boiler . They can be placed in one block or separately. The boiler pressure gauge controls temperature and pressure, it notifies that the device has reached operating condition - the same 1.1-1.5 atm. If the car has one pressure gauge, this thing works for the boiler.
The pump pressure gauge controls the pressure in the brew group. The operating parameters in this case correspond to 9 atm . Deviations from the norm indicate a breakdown.
Causes:
- tubes are clogged with scale (solution: cleaning or replacing with a new one);
- clogging the channels leading to the pressure gauge;
- pressure gauge failure.
Solution : replacement of the unit or tubes at a service center, decalcification.
Requirements for water and filters
It is generally not advisable to use tap liquid for brewing coffee, as it greatly changes its taste and contaminates the parts.
To do this, coffee makers have filters that need to be changed periodically. If the pores are already clogged with lime or other trace elements, this can become an obstacle to the passage of water.
Each filter has its own lifespan; you can find out which one it is from the instructions and replace it - yourself or at a service center. To disassemble the Dolce Gusto coffee machine, you may need special tools.
Bottled water that has gone through several stages of purification is most suitable for filling into a container. If, after replacing the filter, no water comes out of your Dolce Gusto coffee machine, then the problem is not with the filter. It is removed again and the internal parts are completely cleaned of scale. After the final rinsing, the filter can be installed again.
Breakdown of the electronic filling of the coffee machine
Any modern coffee equipment is a clever device that performs a wide range of functions. The more a device can do, the more advanced its control board is. This is one of the most expensive components, the repair of which will cost a pretty penny.
Breakdown of the button board
This thing is responsible for correct operation and switching of functions. A malfunction can directly affect the temperature of the finished drink. The board consists of a huge number of microcircuits and wiring that can burn out, become clogged, or fail. The solution is to completely replace the part.
Thermal sensor failure
The temperature sensor monitors the temperature of the liquid in the boiler, brewing unit, etc. Without this little thing, you won’t be able to make a good, proper drink. The second point is that operating the coffee machine becomes unsafe. This is why timely repair is so important. After diagnostics, the sensor is replaced with a new one.
Temperature controller failure
A controller, or PID controller as it is commonly called, is a unit that provides a high level of temperature stability. Essentially, this is a more modern temperature sensor. This thing evaluates changes in temperature parameters in a constant mode and controls the heaters depending on the evaluation results. If a breakdown occurs, the coffee machine may lose its ability to heat. Repairs are carried out at the service center.
User errors
Trying to save on replacing parts, users buy used spare parts that do not last long. After this, the device can no longer be repaired under warranty, since the operating conditions have been violated.
Not every part is suitable for a coffee maker of this type - they can only be selected at a service center, where they are delivered directly from the manufacturer. Experimenting with expensive equipment can lead to final breakdown and loss of warranty rights.
It is recommended to immediately come to terms with the fact that you will have to maintain the coffee machine and spend money on it, otherwise it will work intermittently.

It is better to carry out a complete cleaning with disassembly. If that doesn't help, it's probably the pump.
Problems with coffee capsules
Well, the last thing I would like to tell you about is why coffee machines do not puncture capsules, or tablets as they are also called. The piercing mechanism is quite simple, so most likely you do not need coffee machine repair, but recommendations that will allow you to correctly pierce the capsule. It all depends on how you direct the tablet into the piercing receiver. You must carefully drop the tablet so that it lands evenly on the piercing surface, then gently press the lever. The slightest misalignment can cause the mechanism to not compress the tablet or throw it back. If pierced correctly, the result should be the same as in the picture.

What to do if the water supply to the coffee machine does not work?
Perform manufacturer's recommended maintenance. Next, inspect all connections. If the equipment is connected to the water supply, make sure that the lines are not blocked; there is water in other appliances and plumbing in the house.
If you cannot fix the problem yourself when the device does not pump water, use. You can call an engineer at your home or office by phone from 7 a.m. to 11 p.m. on a day of the week convenient for you. If necessary, place an order for a call back. We work with famous brands, including Nespresso, Delonghi, Krups, Dolce Gusto. An official guarantee is issued for the services. You are personally present during the repair, you can verify the malfunction of specific components and parts.
Filters for Delonghi, Jura, Saeco, Bosch coffee machines
The main task of the filter is trivial - water purification. However, the quality of the prepared drink and the long-term maintenance-free operation of the equipment directly depend on this. Modern consumables work using ion exchange technology and have a microporous structure, which prevents the device from clogging.
Filtering allows you to:
- retain large impurities such as hair, rust, sand;
- clean the liquid from chemicals, in particular from chlorine, calcium, magnesium, etc. If we talk about calcium, this is the main enemy of the internal filling of a coffee machine. It builds up on heating elements, forming scale. If you do not delay it and neglect regular decalcification, the device will break down.
There was noise from inside, the pressure from the horn decreased
If you notice that the water from the coffee machine is flowing poorly and at the same time there is an extraneous whistle or noise, it means that the mesh or the filter itself in the horn is most likely clogged. It won’t be difficult to wash it, not to mention that such repairs won’t take much time. Special products are sold for cleaning coffee machines or coffee makers from grease. You can also carefully remove debris with a toothpick. The main thing is that when repairing a coffee machine on your own, do not scratch the internal containers, as even small scratches will retain the ground coffee, which contributes to the rapid clogging of the equipment.
If the coffee machine is noisy and does not pour coffee well, it may even be because the filter is clogged due to the coffee beans being ground too strongly. Start the repair by opening the container with coffee beans and checking the grind size. If you see coffee dust, adjust the grind size manually (many coffee machines have this function). Well, the last reason for extraneous noise is wear of the internal pump mechanism, as a result of which the coffee machine makes noise, hums and does not pour water well. In this case, the weak pressure can only be repaired by replacing the pump.

Which coffee shops can you take away more from?
Coffee shops are different, so the approach should be different. The higher the revenue of the coffee shop, the greater the amount that can be taken out. Management of successful coffee shops tend to relax. But if things are bad and the point is working in the negative, then checks begin that are designed to identify the cause of the current situation.
Chain coffee shops have inventory control and video surveillance. However, more often than not, several coffee shops have one manager who is unable to fully monitor employees. This allows baristas to cooperate and take quite a lot.
In off-chain coffee shops, where the owner has only one outlet, they often save on accounting systems and video surveillance. At the same time, the owner knows his establishment better and can detect theft in non-standard ways.
Coffee shops operating at events are usually a real mess. There is freedom here for the dishonest barista.
You are using low-quality coffee beans
If you use an automatic coffee machine, you cannot control the temperature and brew time yourself. The only thing you can control is the grain you use. Try not to save money and buy high-quality, fresh grain. It is best to purchase it in a specialty store rather than in a regular grocery supermarket. Choose packaging that indicates the roasting date, and try to find the freshest possible product. Buy the quantity you need for the week.

Safety precautions
There are a few simple safety rules when using a drip coffee maker:
- Do not use the device with a faulty power cord or connect it to an emergency outlet.
- To avoid electric shock if water leaks, turn off the power to the coffee maker immediately.
- A device that is flooded with water must be dried before use.
After self-repair, before operation, it is recommended to connect the coffee maker through a residual current device - RCD. If it works, it is better to entrust the troubleshooting to a qualified technician.
Main varieties
There are several types of models that differ in cooking method, cost and design.
Carob
The horn coffee maker prepares 1 serving of espresso and Americano. It uses compressed raw materials. The device uses pressure to force hot liquid through the coffee. After each use, a person needs to wash the horn.
The carob coffee maker is the most popular and in demand device.
pods
A pod is compressed powder in a paper bag that is enough for 1 standard cup of espresso. Before purchasing a model, you need to find out which filter is suitable for it (ESE or Senseo). The first option is more common in Russia. Pods are sold in 20-40 pcs., and to prepare it, just place the coffee in the hole and press the button.
Pod coffee machines are a new product on the coffee maker market.
Automatic
Automatic devices are recognized as the simplest and most convenient to use, since to brew an invigorating drink, the owner needs to pour coffee beans into a special container and set the desired mode with the press of a button.
Drip
Drip-type electrical appliances have a simplified design, are inexpensive and are capable of preparing high-quality black coffee. A special feature of drip coffee makers is the presence of a filter, which is made from paper, nylon or metal.
Drip coffee makers have a simplified design.
Espresso combine
The combine consists of 2 components:
- Coffee grinders.
- Carob coffee maker.
The device is not very different from standard carob models, but thanks to the presence of grinding knives, the owner does not need to look for ground powder. The only drawback is the complex design of the holder, which makes it quite difficult to remove dirt.
Geyser
Geyser models are divided into 2 parts (upper and lower). The finished drink rises to the top under pressure. Unlike a classic coffee maker, this one has its own heating element. A person can brew up to 6 cups of espresso at one time.
Geyser coffee makers are divided into 2 parts.
Portioned
Single-serve coffee machines use bags containing 7 g of coffee. To brew it, you need to put the filter in the compartment, adjust the temperature, the amount of liquid used and other functions.
Basic selection rules
- Metal case - only a device made of a special metal alloy with heat-resistant properties, has a long service life, and retains its attractive appearance for a long time, regardless of the intensity of use.
- Holder - give preference to a device made of stainless steel, it is easy to maintain, wear-resistant and durable.
- Boiler – maintains the smooth operation of professional equipment, simultaneously prepares espresso, boils water, froths milk, the volume of the boiler is selected based on the number of visitors. The range includes single-boiler, double-boiler and multi-boiler machines.
- Pump – the most practical, easy-to-use remote vortex pump.
- Indicators and sensors - their main function is to protect the device from overheating and breakdowns.
- Electric heating option – treats are served only in hot containers, otherwise they will quickly cool down.
