The main types of errors

Self-service troubleshooting is a great way to save money on your own budget. If someone tells you that the washing machine is very complicated and you cannot repair it yourself, run away from this person urgently, he is incompetent in repair matters. In most cases, you can fix a broken washing machine with your own hands, since the most difficult part here is the control module. Everything else is not difficult.

The error code H1 that appears on the display indicates that there is some kind of error in the water heating system. But this would be too vague an interpretation of the malfunction, so several separate codes were provided:

  • H1 on a Samsung washing machine means the temperature rises too quickly or exceeds its limit values. If in two minutes the water warms up by more than 40 degrees or the temperature approaches the boiling point, the display shows the code H1 (or He1);
  • An H2 error in a Samsung washing machine (or He2) indicates too long heating. If within 10 minutes from the time the heating element was turned on, the water warmed up by less than 2 degrees, this indicates a breakdown of the heating element.

The He2 error of a Samsung washing machine most often indicates a break in the heating element or a lack of its power supply. You will have to figure it out yourself, since you will not receive more accurate information from the diagnostic system. As for the He1 (or h1) code, it appears during intense heating. This happens when the heating element breaks down, when its internal resistance drops and there is a clear overheating.

Samsung H1 Error

The appearance of scale on the heating element is due to the presence of many impurities in the water, which are deposited on the heating element. To avoid this, you can install a filter on the water entering the house.

How to diagnose a breakdown and fix it

Let’s see what to do if the Samsung washing machine gives an error He1 or He2 (as well as H1 or H2). First, let’s figure out the codes with the number 1. If the temperature rises too quickly, it means that the heating element is operating in overload mode. An electrical breakdown to the case is also possible, due to which the water begins to heat up as a result of the reaction from the flow of alternating current. In any case, you need to disassemble the Samsung washing machine and look for a malfunction.

The H2 error in the Samsung washing machine program means no heating. This code appears after the start of washing, when voltage is applied to the heating element. Temperature control is carried out at the same time. If the temperature does not change much in 10 minutes, the above error is shown on the display. In most cases, this means a breakdown of the heating element, or rather, a break. Let’s see how to diagnose and repair a Samsung washing machine.


First, we need to remove and diagnose the heating element. We warn you right away that it will not be easy to get to it. Often you need to remove the front panel for this, since in many models its contacts are located in the front. If you need to remove the front panel, you need to loosen the control panel and remove the rubber seal, unscrew the screws and carefully remove the front part. Not an easy task, especially when you have to put the seal back on.

Next, we proceed to check the heating element, using for this a multimeter operating in ohmmeter mode. We remove the wires from the contacts of the heating element and the temperature sensor, proceed to measurements. We have already said that the H2 error in the Samsung washing machine indicates an open circuit. In this case, the multimeter will show infinite resistance. The normal resistance of a serviceable heating element is 25-30 Ohm, depending on its power.

If the resistance is normal, then this may indicate that there is no voltage on the contacts when the program is started. The electronics of the Samsung washing machine should issue 220 Volts to the heating element. In the absence of voltage, one should suspect the on-board electronics, which for some reason does not supply power. Also, the appearance of the H2 error in Samsung washing machines may be due to a malfunction of the thermal sensor, which incorrectly estimates the water temperature.

No special knowledge or skills are required to work with the multimeter. The main thing is to find from whom you can borrow it for the duration of the check.

The H1 error in Samsung washing machines indicates too much heat. This can happen with a faulty heating element, when it shows less than normal resistance. The same thing happens when there is an electrical breakdown to the case. Testing is carried out as follows. We measure the resistance between the contacts, after which we carry out measurements between the contacts and the case. If the internal insulation is faulty, there will be a low resistance between the case and the contacts, indicating a breakdown.

In total, if the washing machine gives an error (Error) H1, He1, H2 or He2, you should diagnose the heating element and the temperature sensor, and also determine the presence of the heating element power supply. Based on the results of measurements, the following may be faulty:

  • Ten. Overheats or does not heat the water at all;
  • Thermal sensor. Gives the wrong commands to the controller (to carry out the test, control readings of a known good sensor at a particular temperature are needed in order to have something to compare with);
  • Controller. Does not supply power to the heating element.

It would not hurt to check the connecting wires and clean the contact groups. The latter could oxidize to the point of disrupting normal contact.

Error codes H1, He1, H2 and He2 in Samsung washing machines

Thanks to the diagnostic systems in Samsung automatic washing machines, we can diagnose many malfunctions without the help of specialists. To do this, you need to clarify the error code, and then find the decryption. For example, an H1 error on a Samsung washing machine means that something is wrong with the water heating system. If you are familiar with the device of modern household appliances, it means that you can easily eliminate the problem.

Renovation work

If your Samsung washing machine gives an error, and you have already identified the cause of the breakdown, it’s time to start repairing. If a malfunction of the heating element was detected, it must be replaced. Unscrew the fixing screws, carefully remove the heating element from its regular place with shaking movements. Using any auxiliary tools, remove deposits and install a new heating element. Connect it and check the operation of the unit.

Errors in Samsung washing machines can also appear due to breaks in the connecting conductors. In this case, they must be replaced. Find insulated wires of a suitable cross-section and start repair work. Worst of all, if the control board is out of order, it may need to be completely replaced.

Samsung washing machine error H1

H1 error in Samsung washing machine occurs relatively often and confuses even experienced housewives. Every year, technology is acquiring more and more functions, and the dashboard of home gadgets is more like an aircraft control panel. The number of possible errors in the operation of home appliances is also growing, therefore they are indicated using special codes, a list of which is often indicated in the instructions. Today we will tell you what the above error means and what you need to do, what to fix it.

What the error can lead to

The occurrence of an H1 malfunction always causes the system to fail to start or continue the washing process, since the temperature regime will not be observed. If the cause is a malfunction of the inlet valve, the heater will operate in the absence of water. An incandescent heater can burn out, as can the temperature sensor placed on it.

Water heating problem. Error H1

If a similar error is found on the display of your Samsung washing machine, it means that there is a problem with the water heating process. Since the water temperature is important for most washing modes, the further operation of the machine will be suspended if this problem occurs. In this case, the code, depending on the year of manufacture of the device, can be designated both H1 and H0, therefore the exact designation and decoding should be found in the instructions for using the washing machine.


All problems with the water supply valve and the tubular electric heater arise from two reasons: unstable voltage and dirty water. Over time, the inner surface of the heater pipes becomes covered with scale, the walls become thinner. To avoid these problems, the following methods are used:

  • Installation of a ceramic fuse in the heater;
  • Periodic cleaning of the heating element from scale, the use of special agents for the prevention of scale when using hard water (for example, Calgon);
  • Installation of a filter in the water supply system.

The main reasons for the error

The main causes of the H1 error can be:

Malfunctions, short circuit of the tubular electric heater is the main reason for the breakdown of the heating system. Oxidation and wear of wires, combustion from a voltage surge. All this can lead to the loss of contact and the impossibility of the heating process. To check it, open the front cover of the device and remove the protective strip from the heater. Check the heater for rust and damage. Also check if the wire is disconnected. Call the master: he will check the resistance on the element and its wires. A reading below 20 ohms indicates damage or complete combustion of the part. If such faults are found, the master can quickly replace the element.

  • Temperature sensor malfunction. This malfunction occurs much less frequently than the previous one and is detected after checking the heating element. The sensors built into Samsung washing machines are called thermistors and are located directly on the heating coil. You can also check its serviceability by measuring the resistance indicator, in case of low results, the sensor is replaced.
  • Turning on the automatic overheating protection system is another reason for the H1 error. A malfunction occurs most often due to erroneous readings of a thermistor or water quantity sensor, as well as a broken heating element. The problem is solved by replacing the electric heater together with the temperature sensor.
  • Sometimes an unopened intake valve can cause a breakdown. The reason for its malfunction is determined by the wizard, after which the system is debugged and the defective parts are replaced.
  • Output

    Any breakdown of a washing machine is a nuisance that requires a quick solution, since one failed element contributes to the breakdown of the rest. Use preventive measures and call the technician in case of breakdowns, in which case your washing machine will serve you for a long time.

    Samsung washing machine error H1: why it appeared and how to fix it?

    Korean-made Samsung washing machines enjoy well-deserved popularity among consumers. These household appliances are reliable and economical in operation, and the longest washing cycle for this brand does not exceed 1.5 hours.

    Such self-diagnostics, which is performed by the machine software, is able to identify almost any emergency situations, the accuracy of which is 99%.

    How it stands?

    Each manufacturer of washing household appliances denotes a fault code differently. In Samsung machines, the coding of a breakdown or program failure looks like a Latin letter and a digital symbol. Such designations began to appear on some models already in 2006, and now code designations are available on all machines of this brand.

    If, during the execution of the operating cycle, a Samsung washing machine of the last years of production displays an H1 error on the electronic display, this means that there are malfunctions related to water heating. Earlier models of the release could indicate this malfunction with the HO code, but this code also indicated the same problem.

    Samsung machines have a whole series of codes that start with the Latin letter H and look like H1, H2, and there are also double letter designations that look like HE, HE1 or HE2. The whole series of such designations refers to problems associated with water heating, which may not only be absent, but also be excessively high.

    Reasons for the appearance

    At the moment of a breakdown, the H1 symbol appears on the electronic display of the washing machine, and at the same time, the washing process stops. Therefore, even if you did not notice the appearance of an emergency code in a timely manner, you can find out about a malfunction even by the fact that the machine stopped working and emit the usual sounds accompanying the washing process.

    Possible reasons for the breakdown of the washing machine, indicated by the H1 code, are the following.

    The heating of water in the washing machine occurs with the help of special elements called heating elements. Tubular heating elements. After about 8-10 years of operation, this important part fails in some washing machines, since its service life is limited. For this reason, such a breakdown is in the first place among other possible malfunctions.

  • Slightly less common is another problem, which also stops the process of heating water in the washing machine. A breakdown in the contact in the electrical circuit of the heating element or failure of the temperature sensor.
  • Often, power surges occur in the electrical network to which our household appliances are connected, as a result of which a fuse located inside the tubular system of the heating element is triggered, which protects the device from excessive overheating.
  • How to fix?

    When the washing machine displays an H1 error on the control panel, the fault is sought, first of all, in the operation of the heating element. You can do diagnostics on your own if you have a special device called a multimeter that measures the value of the resistance of the current at the electrical contacts of this part.

    To diagnose the heating element in Samsung washing machines, remove the front wall of the case, and then the procedure depends on the diagnostic result.

    • Tubular heating element burned out. Sometimes the cause of the breakdown may even be that the electric wire has moved away from the heating element. Therefore, after removing the machine body panel, the first step is to inspect the two wires that fit the heating element. If any wire has come off, it must be put in place and tightened, and in the case when everything is in order with the wires, you can proceed to the measuring diagnostics of the heating element. You can check the heating element without removing it from the machine body. To do this, check the resistance indicators of the electric current on the wires and contacts of the heating element with a multimeter.
    • The temperature sensor has burned out. A temperature sensor is installed in the upper part of the tubular heating element, which looks like a small black piece. To see it, the heating element does not have to be disconnected and taken out of the washing machine in this case. They also check the performance of the temperature sensor using a multimeter device. To do this, disconnect the wiring and measure the resistance. In a working temperature sensor, the device readings will be 28-30 ohms.
    • Inside the heating element, the overheating protection system has worked. This situation is quite common when a heating element breaks down. The heating element is a closed system of tubes, inside of which there is a special inert substance that surrounds the heating coil on all sides. When the electric coil overheats, the substance surrounding it melts and blocks the process of further heating. In this case, the heating element becomes unusable for further use and must be replaced.

    Modern models of Samsung washing machines have heating elements with a reusable fuse system, which are made of ceramic components. In conditions of overheating of the spiral, part of the ceramic fuse breaks off, but its performance can be restored if the burnt parts are removed and the remaining parts are glued together with high-temperature glue. The final stage of work will be to check the performance of the heating element with a multimeter.

    The operating time of the heating element is influenced by the hardness of the water. When the heating element comes into contact with water during heating, the salt impurities contained in it are deposited in the form of scale. If this plaque is not removed in a timely manner, it will accumulate every year the washing machine is in operation. When the thickness of such mineral deposits reaches a critical value, the heating element ceases to fully perform its functions of heating water.

    In addition, limescale contributes to the rapid destruction of the heating element tubes, since corrosion forms on them under the scale layer, which over time can lead to a violation of the integrity of the entire element. Such a turn of events is dangerous in that the electric spiral, which is under voltage, may come into contact with water, and then a serious short circuit will occur, which may not be eliminated by replacing the heating element alone. Often, such situations lead to the fact that the entire electronics unit in the washing machine fails.

    For the options for eliminating error H1, see below.

    Samsung washing machine error HE1

    The HE1 error in the Samsung washing machine is quite common and can appear at any stage of the work of the “home assistant”. There are not very many reasons for it, but they all pose a great danger, and if the control module stops the washing machine, giving a similar error, it actually saves your property from serious damage. How this error is deciphered, what kind of malfunction is capable of generating it and how to fix this malfunction, read about all this in this article.

    First, let’s decipher

    If we are talking about the self-diagnosis system of Samsung washing machines, then we can say with confidence that any code starting with the English letter “H” indicates problems with the heating element, and subsequent letters and numbers specify the type of problem. In our case, HE1 literally means that the water in the tank heats up by more than 40 0 ​​С in 2 minutes. What is it about? The heating element heats up too quickly, and it does this regardless of the algorithms that are laid down by the washing program.

    The HE1 error prompts the master to think that the heating element is working, there is no open circuit, but something makes it work incorrectly. In this, plus the three-digit codes of the self-diagnosis system of Samsung washing machines, they transmit information about the breakdown more accurately than two-digit ones, allowing the master to save time on troubleshooting.

    You don’t have to go far for an example. Samsung washing machines with a two-digit self-diagnosis code have error H2, which means a breakdown of the heating system. What kind of breakdown is this, what is its nature, go and guess. Until you open the washing machine, you will not understand. The three-digit code allows you to search for a breakdown purposefully, by the way, about breakdowns.

    Possible reasons for the appearance

    If you see an error code HE1 on the display of your washing machine, get ready to troubleshoot, since this is definitely not a power surge or a short-term electronics failure. What breakdowns cause the HE1 error? There are two such breakdowns: when the temperature sensor fails and when the control board breaks.

    The temperature sensor sends information about the heating of the heating element. Through this sensor, the control module can regulate the temperature of the heating element according to the washing program. If the temperature sensor breaks down, then the control module loses the ability to control the operation of the heating element and by default, after turning on the Samsung washing machine, it begins to warm up to the maximum. At the same time, the control module, without receiving information from the temperature sensor for several minutes, urgently turns off the heating element and issues an HE1 error, stopping the operation of the washing machine.

    Breakdowns of the temperature sensors of the Samsung washing machine are quite common, but sometimes such a sensor has nothing to do with it. What then is the reason for the error? In such a situation, the cause of the error lies in the control module itself. If the track or the triac that controls the heating element burns out, this also leads to the HE1 error, however, the repair is an order of magnitude more difficult and expensive.

    We eliminate the reasons

    The thermal sensor, as a rule, cannot be repaired. It needs to be changed, but in order to make sure that the part is faulty, it must be checked with a multimeter, and only then replaced. To check and replace the temperature sensor, you will have to remove the front wall of the Samsung washing machine. How the front of the washing machine of this brand is disassembled is described in detail in the article How to repair a Samsung washing machine, we will not repeat ourselves. So, having reached the heating element, we do the following.

    • Disconnect the wire from the thermal sensor, and then take out the part from the niche.
    • We measure the resistance of the sensor using a special device called a multimeter. If the device shows zero or one, safely throw out the thermal sensor and put a new one in its place.
    • Then we collect and check the repaired washing machine.

    If the thermal sensor turns out to be intact, there will be no problems with the wires and contacts that supply it, then the matter is in the control module. It is not worth repairing the control module of the Samsung washing machine on your own, since this is a rather complicated matter, the slightest mistake can aggravate the problem and result in significant expenses. Entrust the repair of the electronic part of the washing machine to a professional.

    To summarize, we note that the HE1 error in the Samsung washing machine is deciphered quite simply, but fixing the breakdowns that caused this error can be, oh, how difficult it is. But we are optimists by nature and we believe that you will succeed, the main thing is to read our instructions carefully. Good luck!

    Causes of error H1

    • Short circuit or break of heating element;
    • Breakdown of the thermal sensor;
    • Overheating protection activation.

    Samsung washing machine shows error h1. What to do?

    Modern washing machines only vaguely resemble their ancestors from the past century. If in the past they were mainly analog and could perform only mechanical functions, now each such electrical device is equipped with a minicomputer that controls the process, akin to how the on-board computer of a car monitors everything that happens.

    Thanks to this, a washing machine with a malfunction simply displays an error code on the LED or LCD panel or display on the front of the machine, which allows you to understand what is wrong with it.
    As a rule, each manufacturer has different codes and ways of indicating errors. Samsung washing machines use alphanumeric characters. These are probably the most common fault indications or error codes used for Samsung washing machines. After all, most of them use the same ways to demonstrate that the washing machine has a problem or needs a replacement part. These codes are used on later models from about 2006 onwards.

    Error code H1. Problem with water heating

    For example, if the display shows an H1 error, then there are problems with water heating and you need to fix this in order to continue the normal operation of the device.
    Depending on the region and year of manufacture of the “washing machine”, this code can be designated as H1 or NO, which, in fact, is the same. Problems with the heating element.

    Before starting any investigation of the problem or even removing the cover of your Samsung washing machine, please read and understand this article carefully, paying particular attention to the safety instructions and information on this page, as it is extremely important.

    So, as mentioned above, according to the Samsung washing machine error classifier, the H1 code indicates a malfunction or failure of the water heating system with a heating element. What to do in this case?

    Short circuit or break of heating element

    The first thing to check in the Samsung washing machine, which gives an H1 error, is the operation of the heating element itself. Perhaps, the wires simply oxidized, and the contact disappeared, it could also burn out due to a voltage surge or some other factors.

    To gain access to the heating element of Samsung washing products, you need to remove the front cover, since, unlike other washing machines, the Koreans have them in front, also dismantle the protective cover from the heating element.

    Visually inspect the element for damage and oxidation of the contacts. Make sure they are held securely and not loose. Then use a multimeter to diagnose:

    • Disconnect the wires from the heating element;
    • Measure resistance. If the display of the multimeter shows 1, further searches can be stopped, since it burned out. The reading at the level of 28-30 Ohm indicates the health of the heating element;
    • Also measure the resistance level on the wires that come out of the washing machine, the readings should be approximately the same, if everything is fine with the power supply. Large deviations will signal that the wire is broken. Also on our website you can read an article on how to check the heating element of a washing machine with a multimeter.

    Obviously, if problems arise with wires or heating elements, repairs need to be carried out. Replacing the wire is quite simple, so it makes no sense to describe the list of actions in detail.

    • Unscrew the nuts that hold it against the washing machine tank;
    • With forward movements from side to side, carefully remove the heating element from the seat;
    • We clean the contacts on the tank and the landing site from scale and other contaminants. A contact cleaner is best suited for these purposes;
    • Carefully unpack the new part and place it in its seat. At the same time, make sure that during installation do not shift or break the gum;
    • Tighten the fixing nuts and connect the power wires.

    After all these manipulations, assemble the washing machine and turn on the test wash mode to make sure that the appliance is in good working order.

    Broken temperature sensor

    The appearance of the H1 error in a Samsung washing machine, as a rule, is associated with problems with the heating element, its failure or contact closure. However, there are situations when the heating and its power supply are normal, but the error, nevertheless, still does not disappear.

    In this case, it is worth checking the thermal sensor, or rather its type used for Samsung washing machines, a thermistor. It is located directly on the heating element.

    • Remove the front cover and protective strip, as described above;
    • In front of us there will be a black or gray plastic element located directly on the heating element;
    • It is necessary to check the resistance with a multimeter, if the readings deviate from the norm, a replacement is needed. Working resistance is about 35 kOhm;
    • Disconnect the contacts from it and carefully remove from the seat, then in the reverse order, install a new thermistor.

    Overheating protection tripped

    The final cause of the H1 error in the Samsung washing machine is the overheating protection. Such a nuisance may occur due to the fact that the sensor does not see the water level or is mistaken in the readings of the water temperature, considering that it is above 100 degrees Celsius. As a result, the built-in overheating protection function is activated.

    Basically, such problems can arise due to a blown fuse on the heating element. To solve it, you need to install a new fuse. Not very good news. As a rule, they are inseparable from the heating element itself, so you will have to change the entire assembly part. The replacement mechanics are described above, so there shouldn’t be any difficulties with this.

    So, the reasons for the appearance and how to eliminate the H1 error are clear. Note that its appearance is due, first of all, to poor-quality tap water with many impurities that settle on the heating element, forming scale. It follows from this that as a preventive measure, you can simply install a filter on the water entering the house and forget about this problem for a long time.
