Samsung washing machine does not switch modes

Sometimes housewives, having launched the “home assistant”, discover after a while that the Samsung washing machine does not switch modes. Turning the selector does nothing, and it becomes impossible to adjust the program. This is a fairly common problem, and the reasons for its occurrence vary. Let's figure out what to do in such a situation.

Problems not related to machine breakdown

The inability to adjust the washing program is not always due to some kind of malfunction. Sometimes the reason is trivial, and you can fix it yourself. Let's tell you what can provoke such a problem.

Incorrect installation of the washing machine. It is important to position the SMA drain hose at a certain height, bending it. Otherwise, the water from the machine will “run away” into the sewer by gravity. In this situation, the equipment will be refilled, the cycle will become endless and the control panel may stop responding to user commands. To solve the problem, place the drainage sleeve according to the instructions.
Dust filter clogged. Because of this, the washing machine will not be able to drain the water down the drain and will freeze at one of the washing stages without proceeding to the next step. The solution is to clean the filter element. After this, the “home assistant” will again respond to the user’s commands.
Kink in the drain hose. Another reason why draining water from the washing machine is difficult. The machine also freezes and does not respond to switching buttons and the programmer. Inspect the corrugation and straighten it to resume the flow of liquid.
Garbage plug in the siphon or riser. The machine may freeze during operation for this reason.You can clean the elements yourself or by inviting a plumber.
SMA overload. Each machine is designed for a certain amount of laundry per load. If you exceed the permissible weight, the washing machine will not be able to “scatter” things in the drum and reach the required speed for spinning. So it will hang in the middle of the loop. The solution to the problem is simple - take out a piece of clothing and start the program again.
Imbalance. It happens that things in the drum collect in a lump, which causes the system to become unbalanced. With this problem, the machine cannot continue the cycle and freezes. You need to pause the program and manually distribute the laundry in the washer.
Random failure of the control unit. Sometimes the SMA electronic module Samsung freezes, which causes various problems in the operation of the equipment. Including the inability to switch modes. Rebooting the system will help get things working.

To restart your Samsung automatic machine, unplug it for 15-20 minutes, then restart it.

If it really is a one-time failure of the electronic module, then after a reboot the washing machine will work. These are typical problems that are not associated with any failures in the system. We will also describe situations when automatic machine repair may be required.

Heating element failed

The inability to switch programs on Samsung washing machines is caused by a failed heating element. It would seem, how is this connected? In fact, the explanation is quite simple.

Hard tap water has a negative effect on the heater. The heating element becomes covered with scale. Also, a coating of residues of low-quality powders, lint, threads, hair and other debris appears on the element. The heating element is overgrown with scale

Due to the formed plaque, the power of the heating element is lost.Trying to bring the water to a given degree, the heater works at maximum, and eventually burns out. A corresponding burning smell will indicate the problem. A short circuit in the system causes the machine to refuse to switch modes.

A burnt-out heating element cannot be repaired; the tubular heater will need to be replaced.

When purchasing a new heater, be sure to focus on the model of your Samsung SMA. You can replace the heating element yourself without resorting to the help of specialists. It is located at the back of the device, under the tank.

The breakdown is hidden in the control module

The electronic module “manages” the work of the SMA. Often a Samsung machine stops switching modes precisely because the unit breaks down. Typically, semiconductor elements are damaged or contacts are oxidized: The control module of a Samsung washing machine may break

in the heating circuit (from practice, the heating element relay burns out more often);
in the motor circuit (usually the control triac is the culprit);
in the pump circuit.

Voltage surges in the network and high humidity at the installation site of the SMA lead to breakdown of the control board. It is recommended to entrust the inspection and repair of the electronic module to specialists. This is a difficult job, which will be problematic to perform without experience and knowledge.
