Test service mode of a Samsung washing machine

Samsung test mode During the operation of the automatic machine, you may encounter malfunctions or any breakdowns. The test mode of the Samsung washing machine, provided by the manufacturer of household appliances, allows you to launch the self-diagnosis system of the unit. This feature will help the user check the functionality of all elements of the device, identify existing failures and shortcomings without opening the machine body. We'll tell you how to start a service test below.

Starting the testing process

Testing the Samsung automatic machine from the popular Eco Bubble line will help you understand how to carry out self-diagnosis of the unit. The principle of the described actions will be similar for most other models of the brand. Before starting the procedure, you need to check that the washing machine is connected to utilities. Then you should turn on the device to the mains. Entering the test mode is carried out by simultaneously pressing a simple combination of keys: “Spin”, “Options” plus the network key.

By holding down the buttons, you will hear a characteristic sound and watch the indicators on the operating panel light up. After you release the buttons, the washing machine will go into standby mode for testing. Close the hatch cover tightly; now we can assume that the device is finally prepared for self-diagnosis.

Testing Linear Components

The service test of a Samsung machine is conventionally divided into two stages, and the first of them is checking the linear components of the machine.It allows you to clearly verify the sufficient performance of linear components, such as:

fill valve (filling the drum with water to the required level);
heating element (responsible for heating water);
drain hose (to check for blockages and other things);
Eco Bubble pump (module generating air bubbles).

The button responsible for selecting the water temperature turns on the valve testing mode. By pressing it, you can watch the tank begin to fill with water through the first section of the detergent dispenser. When you press the “Temperature” key again, water will begin to flow through the second section of the tray. This will check both sections of the fill valve. A third press will turn off the liquid filling into the drum.

One press of the “Spin” button will allow you to test the serviceability of the drain hose. The second is to turn on the Eco Bubble pump. A third press will turn off the pump. If you are sure that there are no problems with draining water from the drum, proceed directly to checking the Eco Bubble pump; to do this, quickly press the spin button twice in a row. Now look through the hatch door. Bubbles should begin to appear in the water with which the drum is filled, this indicates that the bubble wash function is functioning properly.

The “Options” button will help you check how the heating element works. Pressing the key will turn on the heating element for a few seconds. If no changes occur on the control panel of the machine, then the heater is working. If there are any problems with the heating element, the device will display an error on the heating element.

Checking sensors and motor

Testing the performance of various sensors and the SMA motor is carried out by rotating the knob for switching washing programs. By setting the selector to a certain mode, you can diagnose a separate part of the device. We'll tell you where to point the pen to test the motor, temperature sensor, level sensor, and main power board. test mode Samsung_2

Setting the selector to the “Spin” mode will display the current frequency of the signal from the water level sensor in the tank on the digital display of the machine. For example, flashing 24.16 symbols on the screen will indicate that the frequency signal of the sensor is 24.16 kHz. You can check how this value changes at the drain; the frequency should increase by about 2 kHz.
Directing the knob to the “Rinse + Spin” position will show the current temperature of the water in the drum. This checks the serviceability of the temperature sensor.
Setting the “Quick Wash” program will display the status of the main power board SMA on the screen. If the OT signal, or Okey Test, means the test passed well, the appearance of the NT (Not Test) icon indicates a board malfunction.
Moving the selector to the “Hand Wash” position allows you to check the motor rotation speed. By selecting this position and pressing the “Start/Pause” button, you will see that the drum will begin to spin, this confirms that the motor is working. If an element is defective, the display will display information about a motor rotation failure.
Directing the mode switch knob to the “Synthetics” program will allow you to visually check the drum rotation speed from zero speed to the maximum possible. Adjust the knob and press the Start/Pause button, speed information will be displayed on the option LEDs.After the test is completed, you should turn off the rotation of the reel using the “Start/Pause” key.

Test diagnostics of a washing machine will help the user in a short time to check the operation of the device’s systems, as well as to identify possible malfunctions. The service test will tell you where to look for the main cause of the washer failure, be it problems with the inlet or drain hose, problems with the SMA motor, water level sensor or main board.
