What does error h2 mean on a Samsung washing machine, how can I fix the problem?

During operation of the Samsung washing machine, malfunctions may occur. The device signals them by displaying a specific error code in the form of letters and numbers.

One of them is h2. You can try to fix the problem yourself, or if you have a complex problem with your Samsung washing machine that displays error code h2, you can seek the help of specialists.

What does the code mean?

An error coded “h2”, as a rule, appears at the beginning of work, when things are placed in the drum, water is drawn in and its heating should begin. The code may appear on the display either a few minutes after the start, or after a few seconds. This depends on the type of damage and the selected washing program.

For machines without a display, the following condition may indicate a failure:

• blinking mode indicators;
• backlighting of temperature indicators at 40°C and 60°C or “Cold water” and 60°C.

On some programs that do not require heating the water, the washing machine may still operate normally.

Decoding

Error “h2” and its analogues are interpreted as a malfunction associated with the heating element (heating element).

In this case, the water is not heated or, on the contrary, occurs very intensively. At the same time, the breakdown of the heating element does not affect washing with the “cold water” setting, allowing it to be carried out as usual.

H2 is issued in a situation where the heating in 10 minutes is less than 2°C.

“h2” and “2h” on the display: what is the difference?

When a code of numbers and letters appears on the display, you must carefully consider the sequence of symbols. So, “h2” and “2h” are different messages indicating certain conditions in the operation of the washing machine:

• 2h – amount of time until the end of the cycle;
• h2 – problem with the heating element.

Reasons for appearance

Throwing error h2 caused by the following failures:

1. Heating element malfunction. It can be eliminated by replacing it with a working element.
2. Thermal sensor malfunction. It needs to be replaced. Since in most models the temperature sensor is built into the heating element, the entire heating element is often changed.
3. Control board malfunction. Replacement and re-soldering of burnt elements (tracks, relays) is required. If the reason is in the processor, they change it. Less often, the entire board is changed.
4. Damage to the wiring connecting the control module and the heating element. It is necessary to replace damaged wires or the entire cable.
5. Incorrect machine connection.

DIY repair

Fixing a broken heating element is most often a task that requires skills and the necessary minimum of tools.

It's better to start with the simplest steps:

1. Check the device's connection to the network. If an extension cord or tee was used for this, then the connection should be made directly.
2. Turn off and after a few minutes turn on the machine again, starting the same mode in which the failure occurred before.In this case, you don’t have to add washing powder.
3. If operation has started normally, you can continue using the machine. The failure was probably accidental.

Attention will need to be paid to:

• heating element;
• temperature sensor;
• control module;
• wiring/loop.

If you do not have the skills to repair equipment, you must call a specialist.

Replacing the heating element and temperature sensor

The location of the heating element in Samsung machines depends on the model. The temperature sensor is an element built into it.

The heating element can be accessed as follows:

1. Disconnect the washing machine from the power supply and water supply.
2. Pull out the cuvette for filling the washing powder.
3. Pull out the washing machine so that it is easily accessible from all sides.
4. On the back of the device at the top, unscrew the screws holding the top panel.
5. Pull slightly towards you and remove the cover to gain access to the elements of the washing machine.
6. Unscrew the screws located near the hole for the powder receptacle.
7. Remove the seal around the hatch. To do this, find the wire with the spring under the elastic band and first remove it. Separate the seal and remove it towards the drum, inward.
8. Remove the front panel of the machine.
9. The heating element in most models is located at the bottom. Disconnect all contacts that go to the heating element. Unscrew the retaining screw.
10. Pull the heating element towards you, shaking it.
11. Check the heating element separately and the temperature sensor separately using a multimeter. This can be done even without removing the heating element.
12. If the “ringing” of one of them does not give a positive result, the part is replaced with a new one.
13. Clean the seat of the heating element from debris.
14. Insert a new heating element in place of the damaged one, secure it, connect all the wiring in the same order as it was.
15. Reinstall the seal and all removed panels and secure with screws.
16. Connect the washing machine to the communications.
17. Test the operation of the machine.

All work must be carried out in good general and local lighting.

Thermal sensor is a device located at the base of the heating element.. To replace it, you need to remove the heating device itself. After replacing the part, all electrical connections are made.

The following video will help you visually and in great detail familiarize yourself with the process of replacing the heating element:

Replacing wiring and control module

In order to get to the control module, it is necessary, as in the case described above, to remove the top cover from the washing machine. After this, remove the board by disconnecting the wires.

The control board itself is secured with screws. You can replace it completely - with an identical one, installing it in its original place. But in some cases, the module is subject to repair - re-soldering the tracks and replacing burnt out elements.

When completely replacing the control module, a new complication may arise - the need to reprogram the unit, which is very difficult to do on your own. In order to identify all the problems and make a high-quality diagnosis, it is advisable to contact a specialist.

To clarify the breakdown of a specific element in the diagram, in order to carry out selective repairs rather than replacing the entire module, a “ringing” is carried out using a multimeter.If the problem is in a specific board element, it is replaced. Broken cable wires require complete replacement. Using a soldering iron, the cable is removed and replaced with a new one.

Prevention measures

In order for the washing machine to serve for a long time, without failures and the “h2” error, It is necessary to take a number of preventive measures:

1. Poor water quality is one of the main problems leading to heating element failure. Hard water causes scale to form on the heating element. Therefore, it is advisable to have a filter to purify the tap water entering the washing machine.
2. Periodically cleaning (running) the washing machine at high temperature with citric acid or another descaling agent will help prevent serious breakdowns in the future.
3. Preventing voltage surges will help keep your equipment in working order. Sudden surges can cause devices to burn out. All necessary parameters are indicated in the passport.
4. You should not place containers of water on top of the machine, as this increases the likelihood of moisture getting into the control module located at the top of the device.

Recommendations

How to care for your Samsung washing machine The following expert advice will help:

1. It is advisable to buy a washing machine at an official point of sale, with warranty service provided.
2. If it is necessary to replace parts, it is advisable to use original spare parts. This will guarantee their perfect combination with all components of the device.
3. The washing machine should not be constantly in a damp room, as this will cause moisture to get on the electronics and other parts, causing oxidation of the elements, including the control module.
4. Care must be taken when transporting/moving the washing machine, as excessive shaking can lead to broken contacts, damage to wiring and other malfunctions.
