For many years, washing machines of the Korean company Samsung have been popular and in demand in the consumer market. Such demand for them arose due to the quality characteristics and the duration of the operational period. But, despite the high performance, washing appliances can fail for various reasons and at any time.
Today, many models of washing units are equipped with displays that display various information that notifies both the execution of the washing mode and errors in their work. If there is a problem with the machine, a specific code will appear on the display. He points to the "culprit" of the breakdown. The error he2 of the Samsung washing machine, according to user reviews, most often appears on the display. Consider what it means and what are the options for eliminating it.
What does it mean?
Error HE2 Samsung washing machine notifies you of a problem with heating water from the water supply to the tank. With the quality functioning of the device in the “washing” mode, the water heating indicator should increase within 10 minutes after starting the program. If this does not happen, then the control system will report a malfunction in operability by highlighting the code HE2 on the display. In this case, the "culprit" of the breakdown is the heating element of the Samsung washing machine, which performs the function of heating cold water.
Reasons for the HE2 error on the display
The error code in question may appear on the washing machine display if:
- failure of the heating element;
- malfunctions of the temperature sensor built into the inside of the tubular heater;
- chip malfunctions;
- disconnecting the wires connecting the heating device to the control module.
Samsung washing machine HE2 error: how to fix without replacing the heater?
Based on the fact that when replacing the heating element, it is necessary to dismantle some body panels, as well as to exclude other "culprits" of the breakdown, the following parts should be diagnosed:
- Checking the performance of the elements for connecting the machine to the electrical network. Exclude the use of additional connections, a tee and an extension cord when plugged into an outlet. Check the connection of the conductors of the cable of the equipment with the plug terminals.
- Fault in the operation of the control module. Disconnect the machine from the power supply, and then reconnect it to electricity. Restart the machine by setting the "wash" mode.
If performing these steps did not remove the HE2 error from the display of the Samsung washing machine, then in this case you need to start dismantling the panels that are the basis of the appliance case.
Why can a heating element fail?
The causes of failure of the heating element are as follows:
- Formation of scale deposited on the tubes. Scale is an obstacle to the transfer of heat generated by an electrical part to cold water. Formed as a result of hard water and the use of detergents, hard deposits have poor thermal conductivity. Due to the slow heating of the water in the tank, the heating element overheats, and eventually the part fails. Scale is also the cause of the formation of a corrosive 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 rate of detergent. It is necessary to follow the proportions recommended by the manufacturer.
Important! To prolong the 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 operation and water hardness) drive it to “idle” in the “Cotton 60 C” mode ° with the additiona special descaler or regular citric acid.
Preparatory process for dismantling the washing machine
Before direct repair, it is necessary to perform preliminary work, which are as follows:
- Preparing the place for dismantling: free access to equipment, as well as enough free space for the location of the removed parts.
- Disconnecting the appliance from the mains.
- Stopping the water supply to the machine by setting the tap to the “closed” position.
- Performing disconnection from other communications.
- Remove the remaining water using the drain filter located in the lower plane of the front panel.
- Installing the unit on the prepared space.
Required tools
To carry out repair work to replace the heating element in the Samsung washing machine, the following tools are needed:
- wiring pliers or pliers;
- set of keys;
- screwdriver with several nozzles that differ in geometric shape;
- electrical multimeter;
- lubricant.
How to disassemble a Samsung washing machine?
The process consists of several stages:
1. Removing the upper frame base:
- using a screwdriver, unscrew the screws (2 pcs.) on the back of the case;
- remove the panel by slightly moving it back.
2. Control panel removal:
- remove the container intended for detergents. To do this, pull it out to the stop and press the latch installed between the sectors of the container;
- unscrew two fasteners installed on the internal base of the dispenser and one fastener located on the right side of the control panel;
- slide the panel and then detach it from the case;
- lay the control panel on the top plane of the frame.
3. Removing the front:
- removing the rubber seal installed between the round bases of the drum and the hatch. To do this, slightly unscrew the edge of the round cuff, pick up the metal clamp and remove it using a flat head screwdriver;
- disconnecting the door lock system with electrical connector;
- unscrew the fasteners located in the upper and lower plane of the front cover;
- remove the cover from the frame of the machine.
Diagnostic heating element
After dismantling the front cover of the case, a small insulating insert will be visible, with conductive terminals placed at the edges. A fastening element is installed in the middle part of the insert. You should not immediately start replacing the heating device, as the cause of the HE2 error in the Samsung washing machine may be the disconnection of the conductor from the terminal. To do this, you need to test it:
- set the multimeter to the "resistance check" mode, choosing the minimum value;
- carefully shift the conductors from the conductive terminals and the thermal sensor;
- leaningone probe of the device to two contacts of the part;
- determine the performance of the heater: an indicator in the range from 25 to 30 ohms indicates the working condition of the part, and in case of failure, the value will be 0 or 1.
If the heater is suitable for further operation, we perform high-quality connection of conductors with its contacts. If, as a result of diagnostics, it turns out that the heating element is out of order, it will have to be replaced.
Choosing a new electric water heater
You can buy a heating element for a Samsung washing machine in specialized trading companies. Going to the store, you need to find out exactly the model of your device (on the case or in the technical data sheet), as well as its power indicator and geometric shape, which must correspond to the failed heater.
In the event that this information is not available, then it is necessary to select a heater in the presence of a worn 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.
The process of replacing the heating element
To remove a worn part, you need to perform several steps:
- using a socket wrench, remove the nut located on the insulating insert;
- loosen the device slightly by holding its contacts with your hands;
- apply a light blow to the stud on which the fastener was installed. You can use a small hammer or socket wrench for this;
- to remove the worn part from the seat, use a screwdriver, which needs to pry the part a little;
- remove the device from the inside of the tank.
The seat is free, proceed to the installation of the unused heater:
- checking the resistance of a new device with a multimeter;
- clean the place from accumulated dirt and scale;
- we process the sealant with a special substance WD 40;
- installing a new heating element for Samsung washing machine;
- insert temperature sensor;
- we connect the conductors to the heater contacts.
Repair work to replace the electric heater has been completed and the panels can be installed.
Final stage
After completing the full cycle of repair work, we proceed to connect the machine to all systems:
- installing the unit in its original place;
- connection to the sewer system;
- setting the faucet to the "open" position;
- connecting the machine to electricity;
- starting the machine in the "wash" mode.
If within 10 minutes from the start of the launch does not appear onThe display code is he2, which means 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 carry out periodic cleaning of the device using citric acid or special products containing it.
