What does error 3e indicate in a Samsung washing machine?

Malfunctions during operation of the Samsung washing machine are displayed on the display. When error code “3E” appears on a Samsung washing machine, the washing cycle stops.

You can try to cope with the situation and restore normal operation on your own; in difficult cases, you will have to call a specialist.

We will talk about malfunctions and ways to eliminate them in the article.

What is this, what does it mean?

The appearance of “3E” on the display indicates a malfunction associated with the tachometer. This is a device that controls engine speed.

Other names for this small device are tachogenerator and Hall sensor. It is used to measure engine rotation speed. 3E can also signal problems with the engine itself that interfere with its rotation.

For machines that do not have a light screen, malfunctions can be indicated by the blinking of all washing mode lamps.The topmost and second from bottom temperature indicator lights should light up at the same time.

An error related to the operation of the tachometer is quite rare., when compared with the frequency of other failures.

Possible reasons

An error on the display of the “3E” washing machine may be caused by circumstances that can be eliminated independently or by serious breakdowns that require the participation of a specialist.

The most common causes of the error include:

1. Finding a foreign object between the drum and the tank. In new machines, this situation can arise even through the fault of the manufacturer.
2. Drum overload.
3. The machine's drive belt tension is loose.
4. Malfunctions in the operation of the control module, tachometer.
5. A drop in the power level of the engine itself. The cause may be a broken winding or worn brushes.

When changing program

This situation is characterized by stable operation of the device, but when changing the program, “3E” or one of the variants of the failure signal is displayed on the display.

A similar problem can arise as a result of oxidative processesthat affected the shaft surface or the tachogenerator. During repairs, the technician will replace the damaged surfaces.

Stopping work after water has been collected and a number of drum revolutions have been made

A problem with the tachometer can be indicated by a situation in which water fills into the car, the drum makes a series of revolutions and stops. Error “3E” appears on the display.

This situation occurs under the following circumstances:

• the tachometer sends too weak or incorrect signals;
• The Hall sensor does not send signals at all.

Drum rotation at unusual speed

When spinning or washing, the drum rotates at a different speed than usual. After several such revolutions, the error “3E” is displayed.

This may indicate that the connection between the tachometer and the engine has become loose.. This results in incorrect signal generation. The problem is eliminated by tightening the fastening.

Machine refuses to spin

The washing machine operation can proceed as usual until the spin cycle. The cause of 3E may be a loose fastening. If this is the problem, the technician will fix the problem without replacing parts. Another possible reason is oxidation. The technician will analyze and repair.

The drum doesn't spin at all

If, after selecting the washing mode, water filled the machine, but then it stopped working, the code “3E” may appear on the display.

The reason for this may be a malfunction in the engine:

• short circuit;
• winding breakage, etc.

In case of serious damage, the engine will need to be replaced. In any case, the repair will be expensive.

Another possible reason is brush wear. They are no longer able to create the necessary electromagnetic field to gain sufficient speed. If the brushes are worn out, the technician replaces them.

Frequent stops, jerky work

In cases where the problem lies in damage to the drive belt, the washing machine may show unstable operation:

• work in jerks;
• stops at the stage of acceleration, etc.

Also, malfunction may indicate physical wear of the electric motor brushes. Due to their defect, speed gain does not occur.The solution to the problem is to replace damaged brushes.

Code appeared at any stage of work

Failure information and cycle stop can occur at any stage:

• wash;
• spin;
• rinsing.

The problem may lie in a broken tachometer circuit:

• broken contacts;
• short circuit;
• violation of the integrity of the wire.

In this case, if possible, the wiring is repaired (cleaning contacts, re-soldering, etc.) or the cable is replaced with a new one.

Stopping work after spinning, rinsing or starting

If there is a malfunction in the control module, error 3E can occur at almost any stage of operation. The signal may disappear due to burnout of system elements (diode, relay, etc.) responsible for engine rotation and communication with the tachogenerator, or tracks on the electrical board.

Or the problem may be caused by the sensor itself (for example, a weak signal, its absence, etc.). After diagnostics, the technician replaces the damaged element.

How to fix it yourself?

If you see an error signal on the display, you can try to solve the problem yourself.

Drum overload

If the drum is filled very tightly, you should lay out some of the things. This must be done even if the total weight of the items does not exceed the maximum allowed according to the passport for the machine.

Random control failure

A one-time appearance of error “3E” on the display may be due to a random failure, when there is no serious reason for this. If the car, as they say, “freezes” and displays “3E”, necessary:

1. Disconnect the device from the network, even remove the plug from the socket.
2. Leave for a few minutes.
3. Insert the plug into the socket.
4. Turn on the washing machine.
5. Start the job.

What to do if the simplest measures do not help? You need to call a technician to fix the problem.

Calling a specialist: when, how, how much does it cost?

For Samsung devices that are under warranty, if any kind of malfunction occurs, you must contact a service center. Information about their location is provided to the buyer at the time of purchase.

You can also clarify this point on the Internet by adding the name of your locality to the search query.

A technician from a company that provides repair services for washing household appliances diagnoses the equipment and offers to carry out work to eliminate the causes of the failure. The warranty period usually takes into account the type of fault repaired and the complexity of the work.

Average cost of work in the capital:

• replacement of the tachogenerator – from 2,400 rubles;
• cleaning of oxidized surfaces – about 2,500 rubles;
• tightening of fastenings – from 2,300 rubles;
• replacement of the drive belt – from 1,000 rubles;
• replacement of brushes – from 1,700 rubles;
• cable replacement/repair – from 1,800 rubles;
• replacement of the control module – from 2,400 rubles, etc.

Calling a specialist privately, not from a company, poses a risk. The work may not be performed efficiently, in violation of technology, and the cost of repairs and spare parts used may be too high.

Also, private craftsmen often replace items that have become unusable not with new ones, but with used ones taken from disassembled devices. Fraud in the service industry also occurs.Requirements for advance payment, receipt of cash for the purchase of an expensive part, etc. should cause caution.

Prevention of malfunction

In order to avoid equipment breakdowns as much as possible and prevent the occurrence of error 3E, It is necessary to adhere to preventive measures:

1. Avoid overloading the drum.
2. Do not force oversized items into the drum.
3. Do not allow the washing machine to remain in a damp area at all times. This can lead to malfunction, oxidation of elements, and their rapid wear.

Recommendations

Modern reliable Samsung washing equipment will last longer if adhere to the following expert advice:

1. For washing, it is better to use special products (suitable powders, capsules, gels).
2. You should purchase a washing machine from certified sales points.
3. Correctly identifying the cause of the appearance of 3E will allow you to quickly resolve the problem. Samsung washing machine service specialists can do this.
