All modern automatic washing machines are equipped with a self-diagnosis function. This was done to identify all malfunctions that arise during operation of the device. This trend has also captured the Korean washing machine manufacturer Samsung.
Malfunctions appear for various reasons. May be due to temporary wear and tear of mechanical and electrical parts. Or maybe it depends on the conditions in which they are used. If any malfunction occurs, “intelligent” machines stop the washing processes you have set. On the display they display a combination of letters and numbers.
This is the error code of the malfunction that has occurred. An ordinary housewife can handle many breakdowns of her car. For example, when she cannot open a closed hatch, the filter becomes clogged, the water supply tap is not open, etc.
These code options can be found in decrypted form in the product operating instructions.
Most breakdowns can only be dealt with by a specialist. You shouldn’t start repairs on your own without the skills. Now we will look at some errors of Samsung washing machines, and in more detail we will find out what the h1 error on a Samsung washing machine wants to tell us, as well as ways to troubleshoot problems in which it appears.
Error interpretation
One of the common errors found in washing machines of the Korean manufacturer is code H2, indicating a malfunction of the water heating system. The combinations of symbols H2 and 2H should not be confused: if the first value is an error, then the second indicates the time remaining until the end of the wash. The letter H here stands for hours, i.e. 2H lights up on the screen indicate that there are 2 hours left before the end of the program.
Error 2h (not to be confused with error h2)
As a rule, error H2 on a Samsung washing machine is displayed if, ten minutes after starting the program, the water temperature in the device’s tank has increased by less than two degrees.
If your device does not have a digital display, it will also be able to report a problem. In this case, all indicators will start flashing, except one of two pairs: temperature 40 C and 60 C or 60 C and cold water. These pairs will glow continuously.
In the event of a breakdown and error code H2, the device may stop working. However, some machine models can continue to be washed, but in cold water. It is very easy to determine this; you just need to touch the glass on the loading hatch door with your hand: it will be warm if the water heats up.
Online diagnostics of a washing machine
If your machine stops washing or rinsing clothes normally, then some kind of malfunction or breakdown has occurred. You can try to find the problem yourself.
Let's look at diagnosing and solving problems:
- After gaining access to the heater, be sure to remove the terminals from the contacts and check with a tester. The resistance of a working heating element is 30-35 Ohms. And it should be constant, not “jumping”. That is, do not change the values at the time of measurement. If there are inappropriate parameters, set a new one.
- We check the integrity of the contacts and the absence of oxidation. We use a multimeter to test the wires from the heater to the control module. It happens that they break at a bend. Koreans are very economical with the length of wires - there is no excess.
- The resistance of the NTC sensor for Samsung washing machines at room temperature is 12 kOhm. When heated, it should decrease. If the characteristics do not correspond, then replacement is necessary.
- The temperature in the tank can exceed 100°C if the NTC sensor is faulty or the wires coming from it are damaged. In this case, faulty elements are also changed. If there is no water in the tank during washing, then you need to check the filling system for blockages.
Important point! There are treacherous situations with a tubular heater. It shows normal resistance, but there is a leak to the housing. This can lead to error H1 or strange malfunctions in the operation of different wash cycles.
Causes of error H2
If an error appears on the device screen indicating that the water is not heating, you need to know what problems it indicates and what to do to correct them. Typically, the H2 code indicates problems with one of the following components:
- A heating element,
- Temperature sensor,
Temperature sensor location
- Wires connecting the control module and heating element,
- Electronic module.
The first thing you need to do is try to “reset” the washing machine, from time to time this helps. To do this, you need to unplug the device from the socket and return it back no earlier than thirty minutes later. If the problem is not resolved, you should move on to other actions.
Choosing a new electric water heating device
You can purchase a heating element for a Samsung washing machine from specialized trading companies. When going to the store, you need to know exactly the model of your device (on the case or in the technical passport), as well as its power indicator and geometric shape, which must correspond to the failed heater.
If this information is missing, then it is necessary to select a heater if there is a worn-out electrical device. Spare parts for Samsung washing machines, as a rule, can also be ordered at most service centers or via the Internet. In this case, information about the device model is required.
Replacing the heating element and temperature sensor
The heating element is the most vulnerable part of washing machines from a Korean manufacturer. Its replacement is carried out through the front wall; the device has to be disassembled almost completely, this significantly complicates repair work. To work, the owner of the device will need screwdrivers and a multimeter.
Now you need to do the following:
- pull out the powder tray and disconnect the drain filter,
- remove the top cover,
- Unscrew the screws, carefully remove and place the front panel of the washing machine on top,
- remove the lower decorative panel using a slotted screwdriver,
- remove the metal clamp attached to the cuff and carefully tuck it inside the drum,
- remove the screws holding the front of the machine around the perimeter, disconnect it and move it to the side,
Removing the front panel
- in the lower part of the tank, near the counterweight, there are contacts for the heating element. You need to check the resistance using a multimeter. If the heating element is working properly, the value will be 25-30 Ohms; in case of a breakdown, the numbers 0 or 1 will appear on the display,
- if the heating element is really damaged, you should disconnect the wires from it and unscrew the bolt holding it,
- Shaking slightly, you need to pull out the element. If all else fails, apply WD-40 lubricant to the base and let it sit for five to seven minutes.
- remove the heater,
- install a working heating element,
- Assemble the car.
To change the temperature sensor, the same difficult work must be done. This element is located next to the heating element or at its base. It should be replaced and then the car should be reassembled.
Why can a heating element fail?
The reasons for heating element failure are as follows:
- Formation of scale deposited on the pipes. Scale is an obstacle to the transfer of heat generated by an electrical component to cold water. Formed as a result of hard water and the use of detergents, solid deposits have poor thermal conductivity. Due to the slow heating of water in the tank, the heating element overheats, and ultimately the part fails. Scale also causes the formation of a corrosion process, which leads to the destruction of the metal base of the tubes.
- Manufacturing defect. If this fact is established by the examination, the consumer has the right to free repair or replacement of the washing machine.
- Exceeding the established norm of detergent. It is necessary to follow the proportions recommended by the manufacturer.
Important! To extend the service life of the heating element, experts recommend using “Calgon” for washing machines when washing to soften the water, or once every 1-3 months (depending on the frequency of use and water hardness) running it “idle” on the “Cotton 60 C” mode °" with the addition of a special descaling agent or regular citric acid.
Replacement of wires and repair of electronic module
In order to find the faulty wire, you need to use a multimeter. With its help, you need to ring all the wires connecting the heating element and the control module, and then replace the faulty one if it is found.
Repairing the control board is a more complex process. To fix it, you need to know how to do this kind of work. Otherwise, you can completely damage the electronic module. In some cases, to repair it, it is enough to solder the burnt out contacts, but to do this you need to detect them. It is very difficult to do this yourself, so it is better to contact a service center and call an experienced specialist. You should also be aware that when repairing the central board, a software update may be required, which is extremely difficult to do on your own.
Who to entrust repairs to?
If the washing machine is under warranty service at the time of the breakdown, it is advisable to contact Samsung service. The current list of the nearest branded, field and partner centers is available on the manufacturer’s website.
Malfunctions that are not related to violation of operating rules or mechanical damage are eliminated free of charge within the validity period of the warranty card.
If necessary, the washing machine is replaced. After the warranty period expires, there will be a charge for professional repairs.
Finding a repair shop
If you can’t contact Samsung service, you’ll have to choose from a variety of workshops yourself. A corresponding query in any search engine will help you find them.
It is necessary to study the websites of services that must contain:
- Company contacts.
- Documents that confirm the legality of the provision of services.
- Prices for main types of work.
It would be a good idea to study customer reviews on reputable third-party resources.
The unit will last longer if, when replacing, you use only original parts or analogues recommended by the manufacturer. Their availability must be clarified immediately.
Choosing a private master
If it is not possible to contact the manufacturer’s service or a well-known network of repair shops, owners are forced to look for a private specialist. It is better if he is recommended by friends and colleagues who have used his services.
It is worth refusing to cooperate if the master:
- Gives you a price for repairs on the first call. It is impossible to assess the condition of the washing machine over the phone, so the final cost of the work can only be announced during the visit.
- Asks for advance payment. Professionals carry out diagnostics free of charge, and are asked to receive remuneration for services rendered after the repair.
- He persuades me to sell the unit for next to nothing, since it cannot be repaired.
Another disadvantage of private specialists is the lack of a warranty period after repairs.
Approximate price
How much you will have to pay to resuscitate a smart assistant depends on the model and complexity of the breakdown. The most expensive problem is the need to replace the software.
According to statistics, in 85% of cases the software fails in the first year of operation of the unit and is associated with a manufacturing defect. In this case, the warranty card will save you. The washing machine will be repaired or replaced free of charge.
If the service life significantly exceeds the warranty period, and the technician insists on reinstalling the software, it is possible that he is a fraudster.
Repair work that does not require disassembling the machine:
- cleaning the drain filter;
- removal of foreign objects, blockages;
- replacing the cord, buttons, door or parts thereof.
The cost of repairs is from 900 to 1700 rubles.
With partial disassembly:
- repair of wiring, control module;
- cleaning the drain system pipe;
- replacement of motor, sensors, belt, valves, pump, electronic module.
The price of work is from 1500 to 3000 rubles.
A technician’s visit to your home and diagnostics are usually free. If repairs are not required, payment will range from 400 to 1000 rubles.
The cost of spare parts and consumables is not included in the price list. The location of the washing machine in a hard-to-reach place can change the price upward.
Bottom line
If code H2 is displayed on the digital screen of a Samsung washing machine, this indicates a malfunction of the water heating system. Most often, the heating element, the weakest and most vulnerable point on devices from a Korean manufacturer, fails, as well as the temperature sensor. Less often, error code H2 notifies about a break in the wires connecting the heating element and the electronic module, and very rarely about a breakdown of the control board.
You can replace the heating element, temperature sensor and wires yourself, the main thing is to know how to fix the breakdown and be confident in the successful outcome of the repair work. To repair the control board, you should call a qualified specialist from the service center to prevent the situation from worsening.
The most common cause of heating element failure is scale formed on it as a result of the presence of a large amount of foreign impurities in the water. To avoid such malfunctions, it is recommended to install a special filter on the water entering the house.
Problems with draining water (E2, 5E or 5C)
It happens that incorrect operation of the washing machine is manifested by the fact that the water drainage does not work. In this case, the following designations appear on the display: E2, 5E or 5C.
If it is difficult to drain water from the washing machine, then you need to check the outlet of the drain pump: it may be clogged with debris and foreign objects
This encoding draws our attention to the possible presence of the following problems:
- there is some physical obstacle preventing water from draining from the hose: it is clogged or pinched;
- the hose is connected to the machine incorrectly;
- the unit pump has failed;
- internal electrical wiring is broken somewhere;
- the blockage could have occurred not in the machine itself, but in the sewer, as a result of which draining became impossible;
- plumbing fixtures were operated in violation of the temperature regime, and the water in them could simply freeze.
In order for the drain to continue to work properly, the possible causes of problems should be eliminated one by one.
You need to check the permeability of the sewer, sniff to see if there is a smell of burnt wiring, check the hoses and change the pump if it is not working.
The final stage
After completing the full cycle of repair work, we proceed to connecting the machine to all systems:
- installation of the unit in its original place;
- connection to the sewer system;
- setting the water tap to the “open” position;
- connecting the machine to electricity;
- starting the machine in “wash” mode.
If within 10 minutes from the start the code he2 does not appear on the display, then the error has been resolved.
If necessary, spare parts for Samsung washing machines are not difficult to find. But it is better to prevent premature failure of components by following simple rules for operating the device.
To extend the service life, it is not necessary to use Calgon for washing machines every time, as advertising recommends. It is much more economical to install a special water filter on the inlet hose or periodically clean the device using citric acid or special products containing it.
What does error E1 (E7) mean?
The appearance of code E1 or E7 on the electronic display means that the sensor that monitors the water level in the drum - the pressure switch - is not working properly. It generates an incorrect frequency that does not coincide with the normal wash cycle. Because of this, the machine reacts to the process incorrectly, and in order to avoid problems, it starts the pump to drain the liquid and stops washing, displaying a message about the problem.
Note! The E7 code appears on older Samsung models released before 2007. The error is processed in the same way as in new machines - if the pressure switch frequency is less than 15 kHz (indicating a full drum) or more than 30 kHz (empty drum) for more than 5 seconds.
The code may appear on the display at any time during the wash cycle. But more often this happens in situations:
- During preparation - while the machine pours water into the drum and washes out the washing powder from the tray.
- When the machine begins to refill water to rinse the washed laundry.
In new models there are also other codes, for example, 4E, 4C and 4E. This is especially true for units produced after 2013.
