Thanks to diagnostic systems in Samsung automatic washing machines, we can diagnose many faults without the help of specialists. To do this, you need to clarify the error code, and then find the decoding. For example, error H1 on a Samsung washing machine means that something has happened to the water heating system. If you understand the structure of modern household appliances, then you can easily fix the problem that has arisen.
Main types of errors
Troubleshooting yourself is a great opportunity to save money in your own budget. If someone tells you that the washing machine is very complicated and you can’t repair it yourself, immediately run away from this person, he is incompetent in matters of repair. In most cases, you can fix a broken washing machine yourself, since the most complex component here is the control module. Everything else is nothing complicated.
The H1 error code that appears on the display indicates that some kind of error has occurred 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 limits. If in two minutes the water has heated up by more than 40 degrees or the temperature has approached the boiling point, the display shows the code H1 (or He1);
- Error H2 in a Samsung washing machine (or He2) indicates heating for too long. 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.
Error He2 on a Samsung washing machine most often indicates a break in the heating element or a lack of power supply - you will have to figure this 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 obvious overheating is observed.
The appearance of scale on heating elements is due to the presence of many impurities in the water that settle on the heating element. To avoid this, you can install a filter on the water entering the house.
How to fix the breakdown?
It is believed that the temperature sensor cannot be repaired - it is simply replaced with a new analogue. But you should first verify that the device is faulty by checking it with a multimeter. If the device proves a complete failure, then you can go to the store.
To perform such work, you should remove the front panel of the machine by unscrewing several screws. Having gained access to the heating element, you must perform certain actions:
- disconnect the wiring from the temperature controller, remove the part from its niche,
- measure the resistance indicator. If the device shows “zero” or “one”, then the sensor can be dismantled and thrown away,
- Having installed the new sensor, we assemble the machine in reverse order and conduct a test run.
In the case when the functionality of the temperature sensor is fully confirmed, and the wiring with the contact group is beyond doubt, we look for the problem in the machine control module. It is not recommended to repair this element yourself, since the work involves certain difficulties, and even a small mistake will only aggravate the failure and create additional financial costs. In this case, you should contact the service center for help.
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 look at the codes with the number 1. If the temperature rises too quickly, this means that the heating element is operating in overload mode. An electrical breakdown on the body is also possible, due to which the water begins to heat up as a result of a reaction from the flow of alternating current. In any case, you need to disassemble the Samsung washing machine and look for the problem.
Error H2 in the Samsung washing machine program means no heating. This code appears after starting the wash, when voltage is applied to the heating element. At the same time, temperature control is carried out. If the temperature remains virtually unchanged within 10 minutes, the display shows the above error. In most cases, this means a breakdown of the heating element, or rather, a break. Let's figure out how to diagnose and repair a Samsung washing machine.
Calling a specialist: the price of the issue
To repair a Samsung washing machine, you need to contact a service center that provides support for equipment from this manufacturer. Companies specializing in repairs must have permission to carry out their activities and a staff of qualified specialists.
For machines that are under warranty, independent repairs should be excluded. All damage must be repaired by specialists.
The buyer receives information about the location of service centers and their contact numbers at the time of making a purchase in the store.
For machines that are not under warranty, servicing can be entrusted to specialized service centers for repairing household appliances. Information about them can be found on the Internet, where you can also read customer reviews.
The called technician comes at a convenient time and conducts diagnostics, determining the cause of the breakdown. Most of the renovation work is carried out on site. Upon completion of the repair, the master conducts testing and issues a guarantee for the work performed.
The cost of work depends on the company's policy. may vary by region and company. For the capital, prices are within the following limits:
- replacement of heating elements - about 2,000 rubles;
- replacement of the cable - around 2,000 rubles;
- replacing the control module – about 2,500 rubles, etc.
If a part needs to be replaced during the repair process, its cost will be paid separately. Contacting a home appliance repair company gives you confidence in quality service and a guarantee.
If you contact an untrusted technician privately, you may end up being scammed - poor-quality repairs, paying an inflated tariff, or installing used parts instead of new ones.
Troubleshooting
First, we need to remove and diagnose the heating element. We warn you right away that getting to it will not be easy - often you need to remove the front panel to do this, since in many models its contacts are located on 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.
If the heater contacts are on the back, then you are incredibly lucky - here you just need to remove the back cover, which is held on by screws.
Next, we proceed to check the heating element, using a multimeter operating in ohmmeter mode. We remove the wires from the contacts of the heating element and temperature sensor, and begin measurements. We have already said that the H2 error in a Samsung washing machine indicates a break - in this case, the multimeter will show infinite resistance. The normal resistance of a working heating element is 25-30 Ohms, depending on its power.
If the resistance is normal, then this may indicate a lack of voltage at the contacts when starting the program - the electronics of the Samsung washing machine should output 220 Volts to the heating element. If there is no voltage, you should suspect the on-board electronics, which for some reason are not supplying power. Also, the appearance of error H2 in Samsung washing machines may be due to a malfunction of the temperature sensor, which incorrectly estimates the water temperature.
To work with a multimeter you do not need any special knowledge or skills. The main thing is to find someone you can borrow it from during the check.
Error H1 in Samsung washing machines indicates too intense heating. This can happen with a faulty heating element, when it shows a resistance less than normal. The same thing happens when there is an electrical breakdown to the housing. Testing is carried out as follows - we measure the resistance between the contacts, after which we take measurements between the contacts and the body. If the internal insulation is faulty, there will be low resistance between the housing and the contacts, indicating a breakdown.
In total, if the washing machine displays an error (Error) H1, He1, H2 or He2, you should diagnose the heating element and temperature sensor, and also determine the presence of power to the heating element. Based on the measurement results, the following may be faulty:
- Heating element - overheats or does not heat the water at all;
- Thermal sensor – gives incorrect commands to the controller (to carry out the test, control readings of a known-good sensor at a given temperature are needed, so that there is something to compare with);
- The controller does not provide 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 breaking normal contact.
HE, HC, HC1, HC2, E5, E6, HE1, H1 - no water heating
E5, E6 - these codes are typical for older car models. Let's look at the reasons that lead to this situation:
- The heating element burned out. It is open or short-circuited.
- Damaged contacts or wiring.
- The NTC sensor is faulty.
- If there is no water in the tank or the temperature exceeds 100°.
Diagnostic work
Let's consider the procedure for self-repair. It is important to note that in most Samsung AGRs, the heating element is located at the back of the tank. And in order to access it, you just need to remove the back cover.
Expert opinion
I work in the household appliance repair industry. Extensive experience in restoring washing machines and dishwashers.
Ask a Question
Important! But, on some old-style machines, the heating element is located at the front. And to work with it, you need to perform partial disassembly - remove the top cover, pull out the panel with control buttons, dismantle the front part of the case.
That's it in a nutshell. This is described in more detail in the disassembly lesson. For BOSCH and Siemens machines it is carried out in a similar way.
Repair work
If your Samsung washing machine gives an error and you have already identified the cause of the problem, it’s time to start repair work. If a malfunction of the heating element is detected, it must be replaced - unscrew the fixing screws, carefully, using a rocking motion, remove the heating element from its normal place. 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 begin repair work. Worst of all, if the control board is faulty, it may need to be completely replaced.
Why does it occur
The appearance of codes indicating a breakdown of the heater occurs due to the burnout of the heating element or the activation of protection against its overheating. A fuse or thermal relay can be installed in the power supply circuit to the heating element. Both devices operate when overheated, thereby protecting the heating element from failure.
This situation occurs due to a decrease in the water level in the tank. The cause may be an incorrect connection of the drain hose to the sewer. If it is not secured to the back wall of the unit, and the drainage device is located below the water level in the machine, then it will drain by gravity, because... There is no locking device on the system.
In this case, the heating element periodically remains without cooling and overheats. During the operation of the SMA and poor maintenance, scale forms on the surface of the heater, which will reduce heat removal and contribute to an increase in the surface temperature of the heating element.
Error HE2 in a washing machine may occur due to a faulty control module.
This is often caused by power surges in the network or water (moisture) entering the electronic unit if the SMA is located in a damp room.
An error in Samsung may occur due to a broken temperature sensor or broken connecting lines. Due to the fact that the sensor cannot be repaired, it must be replaced. In some models, the sensor is located on the sealing plate of the heating element, then the replacement should be carried out complete with the heater.
