DIY coffee maker repair

Any electrical device may fail over time. Repairing coffee makers from Delonghi, Saeco or Krups is easy to do. This kitchen appliance is considered one of the easiest to repair and operate.

Design and Diagnostics

Before you start repairing the device, you need to determine what exactly broke in it. This will greatly speed up and simplify the repair process. There are two types of coffee machines:

1. Espresso (with pump);
2. Capsule;
3. Drip.

Their main difference is the working pressure. For drip coffee makers (Bosch - Bosch, Zelmer - Zelmer, Vitek - Vitek), hot water drips through the coffee filter, through which it passes into the cup when it is already a fragrant drink. In an espresso, a stream of boiling water is poured into the cup, passing through a coffee tablet (pressed ground natural coffee). The advantage of using coffee machines - Espresso Electrolux, Binatone, Braun, Philips (Philips) and many others is that they can work without a filter.

Capsule coffee brewing machines have a special container in which ground natural powder is poured. This allows you to brew a drink with or without pressure. The key difference between these functions is that with professional carob coffee makers, you can make foam coffee.

Main problems coffee machines and coffee makers, domestic and professional type:

1. The water stopped flowing. Most likely, just one of the pipes supplying water was clogged;
2. Coffee began to give a strange smell or taste. Not always in this case, an independent repair of coffee makers is required, perhaps you just changed the coffee tablets (they are Dolce Gusto - Dolce Gusto, Nestle, Jacobs, etc.). Another reason may be a clogged filter or cheap material for the device. If the optimum water temperature for brewing coffee is 95 degrees, then the internal parts are heated to 125 and above. As a result, cheap plastic can begin to melt, conveying its taste to the drink;
3. Iced coffee. The heater stopped working;
4. Incorrect dosage of water (found in capsule coffee makers). Damage can be covered both in the engine and in the timer operation scheme;
5. The horn coffee maker does not turn on. There may be several reasons: engine failure, pumps, problems with the power cord;
6. You cannot set the brewing time or cup filling time. Depending on the type of coffee maker, this can be a breakdown of a time relay, control circuit, engine (or one of its compartments).

It is worth noting that after the intervention, warranty repairs will no longer be provided, so if you are not confident in your abilities, it is better to contact a company service center.

How to disassemble a coffee maker

In order to repair any coffee machines (Nespresso - Nespresso, Delongi), you will need to disassemble them first. Step-by-step instructions on how to do this:

1. There are set screws on the back of the coffee machine. They need to unwind and put aside. They can be of several types: hidden, cross and cone-shaped (often found in Indesit). They are removed with a screwdriver, pliers or other suitable tools;
2. If the case is not removed after removing the screws, then it is secured with hidden locks. The latches are located at the bottom of the rear panel. They can not be opened from the outside, so you have to pry it with a knife or a screwdriver;
3. After removing the case, you can start repair work.

If the pipe is clogged up at Delonji, Bork - Bork, Ariete - Ariete or other coffee makers, then for repair you need to use a long thin rubber hose. It runs along the duct and breaks through a blockage. Sometimes for such purposes special brushes on a flexible leg are used, they allow you to clean the tube and remove not only coffee, but also mineral deposits.

Filter cleaning is a little more complicated. With frequent use, various debris accumulates on it: salt plugs, coffee dust, scale. You need to clean it only according to the instructions, because otherwise, you can violate the integrity of the spare part. In most cases, it is allowed to wipe it with a swab dipped in alcohol or another degreaser. Rinse the part thoroughly after washing.

There may also be problems with the filter if water leaks from the coffee maker. This is often found in machines manufactured by Mulinex, Krups, Rowenta, Saeko. A special valve is installed near the filter, which, after turning off the timer, turns off the water supply. If after a certain time the drink did not stop flowing, then the cause is a malfunction of this element. The valve may wear out after frequent use or simply not withstand the accumulated amount of coffee. To check and eliminate the breakdown, you need to disassemble the coffee machine, pour coffee from it and inspect the valve. Please note that it cannot be repaired, so the part changes immediately.

If the coffee machine Redmond, Spidem, Tefal, Siemens and others does not turn on, then urgent repair is required:

1. The first step is to check the power cord. It needs to be examined for an open circuit, and also an additional grounding check. It connects to the terminal clamp, so be careful when diagnosing;
2. Sometimes, domestic coffee machines made in China simply lose contact. It is also found in professional models (zauber, melitta, trevi). In this case, you need to check all the places for connecting the wires to the control circuit;
3. Many modern machines (Senseo¸Siemens, Ufesa) sin with a poor-quality thermostat. For its diagnosis, you need to remove one wire from its end and check the contacts with a tester. With a working element, the circuit must be closed;
4. Also, the coffee maker may not turn on if the heater needs repair. They call him like a thermostat. For many models (Jura Impressa, Miele, Gaggia, Butler) it is made in the form of a disk, so it will be rather difficult to change it, it is easier to try to repair a part or buy a new car;
5. There are also certain secrets to cleaning the engine. In the departments of the care products, special brushes are sold to help clean different parts of the motor without damaging the fragile material. It should be noted that in coffee machines such as AEG, Solis or Unit, the motor has several compartments, each of which is cleaned separately.
